fixes for WiFiClient::write(Stream) (#7987)
fixes for WiFiClient::write(Stream) and Stream transfers
- remove deprecated WiFiClient::write(Stream,size)
- fix and deprecate WiFiClient::write(Stream) to use Stream::sendAll instead of ::sendAvailable
- update ESP8266WebServer::streamFile to use file.sendAll(client) instead of client.write(file)
- remove stream dependence in ClientContext
- Stream::send(): honor timeout in all case, avoid short transfer when output is temporarily full
- example WiFiEcho: show sendAll and sendAvailable

rename ClientContext::wait_until_sent() to wait_until_acked() (#7896)
* rename ClientContext::wait_until_sent() to wait_until_acked()

While looking at #6348 and #6369, and after checking into lwIP sources, it
appears that the tests in ClientContext::wait_until_sent() effectively wait
for all acks on current output buffer. Comments are added.

* host tests counterpart

more lwIP physical interfaces (#6680)
This commit adds W5500 W5100 and ENC28j60 drivers from @njh with credits
They are available in libraries/
An example is added in W5500 examples directory

plus:
* Extract dhcp server from lwip2 and add it to the core as a class.
  It must always be present, it is linked and can be called by fw on boot.
  So it cannot be stored in a library.
* ethernet: static or dhcp works
* PPPServer: example
* bring WiFi.config() to the lwIP generic interface (argument reorder common function)
* move hostname() from WiFI-STA to generic interface
* remove non readable characters from dhcp-server comments
* dhcp-server: magic_cookie is part of bootp rfc
* fixes from https://github.com/d-a-v/W5500lwIP/issues/17
* enable lwip_hook_dhcp_parse_option()
* +ethernet tcp client example in w5500 library examples

PoC cache configuration control (#7060)
* PoC cache configuration control

Expaned boards.txt.py to allow new MMU options and create revised .ld's
Updated eboot to pass 48K IRAM segments.
Added Cache_Read_Enable intercept to modify call for 16K ICACHE
Update platform.txt to pass new mmu options through to compiler and linker preprocessor.
Added quick example: esp8266/MMU48K

* Style corrections
Added MMU_ qualifier to new defines.
Moved changes into their own file.
Don't know how to fix platformio issue.

* Added detailed description for Cache_Read_Enable.
Updated tools/sizes.py to report correct IRAM size and indicate ICACHE size.
Merged in earlephilhower's work on unaligned exception. Refactored and added
support for store operations and changed the name to be more closely aligned
with its function. Improved crash reporting path.

* Style and MMU_SEC_HEAP corrections.

* Improved asm register usage.
Added some inline functions to aid in byte and short access to iRAM.
 * only byte read has been tested
Updated .ld file to work better with platform.io; however, I am still
missing some steps, so platformio will still fail.

* Interesting glitch in boards.txt after github merge. A new board in
master was missing new additions added by boards.txt.py in the PR.
Which the CI flags when it rebuilds boards.txt.

* Support for 2nd Heap, excess IRAM, through umm_malloc.

Adapted changes to umm_malloc, Esp.cpp, StackThunk.cpp,
WiFiClientSecureBearSSL.cpp, and virtualmem.ino to irammem.ino from
@earlephilhower PR #6994.

Reworked umm_malloc to use context pointers instead of copy context.
umm_malloc now supports allocations from IRAM. Added class
HeapSelectIram, ... to aid in selecting alternate heaps,
modeled after class InterruptLock.
Restrict alloc request from ISRs to DRAM.

Never ending improvements to debug printing.

Sec Heap option now pulls in free IRAM left over in the 1st 32K block.
Managed through umm_malloc with HeapSelectIram.

Updated examples.

* Post push CI cleanup.

* Cleanup part II

* Cleanup part III

* Updates to support platformio, maybe.

* Added exception C wrapper replacement.

* CI Cleanup

* CI Cleanup II

Don't know what to do with platformio it doesn't like my .S file.
ifdef out USE_ISR_SAFE_EXC_WRAPPER to block the new assemlby module
from building on platformio only.

* Changes to exc-c-wrapper-handler.S to assemble under platformio.

* For platformio, Correction to toolchain-xtensa include path.
@mcspr, Thankyou!

* Temporarily added --print-memory-usage to ld parameters for cross-checking IRAM size.

* undo change to platform.txt

* correct merge conflict. take 1

* Fixed #if... for building umm_get_oom_count. It was not building when UMM_STATS_FULL was used.

* Commented out XMC support. Compatibility issues with PoC when using 16K ICACHE.

* Corrected size.py, DRAM bracketing changed to not include ICACHE with DRAM total.

* Added additional _context for support of use of UMM_INLINE_METRICS.
Corrected some UMM_POSION missed edits.

* Changes to clear errors and warnings from toolchain 10.1

Several fixes and improvements to example MMU48K.

With the improved optimization in toolchain 10.1 The example divide by 0
exception was failing with a HWDT event instead of its exception handler.
The compiler saw the obscured divide by 0 and replaced it with a break point.

* Isolated incompatable definitions related to _xtos_set_exception_handler.
GDBSTUB definitions are different from the BootROM's.

* Update tools/platformio-build.py

Co-authored-by: Max Prokhorov <prokhorov.max@outlook.com>

* Requested changes

Changed mmu related usages of ETS_... defines to DBG_MMU_...

Cleanup in example MMU48K.ino. Removed stale memory reference macro
and mmu_status print statement. Cleanup printf '\n' to be '\r\n'.

Improved issolation of development debug prints from the rest of the debug prints.

Improved function name uniqueness for is_iram, is_dram, and is_icache by
adding prefix mmu_. Also, made them available outside of a debug build.
Made pointer precision width more specific.

Made some of the static inline functions in mmu_irm.h safe for ISRs by
setting then for always inline.

* Add a default MMU_IRAM_SIZE value for a new CI test to pass.

Extended use 'umm_heap_context_t *_context' argument in ..._core functions
and expanded its usage to reduce unnecessary repeated calls to
umm_info(NULL, false), also removed recursion from umm_info(NULL, true).

Fixed stack buffer length in umm_info_safe_printf_P and heap.cpp.

Added example for creating an IRAM reserve section.

Updated mmu.rst. Grammar and spelling corrections.

* CI appeasement

* CI appeasement with comment correction.

* Ensure SYS always runs with DRAM Heap selected.

* Add/move heap stack overflow/underflow check to Esp.cpp where the event was discarded.

* Improved comment clarity of purpose for IramReserve.ino. Clean up MMU48K.ino

* Added missing #include

* Corrected usage of warning

* CI appeasement and use #message not #pragma message

* Updated git version of eboot.elf to match build version.

Use the replacement wrapper on non32xfer_exception_handler install.

Added comments to code describing some exception handling issues.

* Updated mmu.rst

* Expanded and clarified comments.

Limited access to some detailed typdefs/prototypes to .cpp
modules, to avoid future build conflicts.

Completed TODO for verifing that the "C" structure struct __exception_frame
matches the ASM version.

Fixed some typo's, code rot, and added some more cases in examaple irammem.ino.
Refactored a little and reordered printing to ease comparison between methods.

Corrected `#ifdef __cplusplus` coverage area. Cleaned up `extern "C" ...` usage.
Fixes issues with including mmu_iram.h or esp8266_undocumented.h in .c files.

* Style fixes and more cleanup

* Style fix

* Remove unnessasary IRAM_ATTR from install_non32xfer_exception_handler

Some comment tuning.

In the context of _xtos_set_exception_handler and the functions it registers,
changed to type int for exception cause type. This is also the type used by gdbstub
and some other Xtensa files I found.

Add valgrind mocked test to CI (#7501)
Run valgrind on host mock example runs to catch more bugs in CI.  These
tests would have caught the problem in #7464 before users did.

Add a list of some randomly picked examples to run, and add an option to
run the loop exactly once in the host mock routine, so the test will
actually exit under valgrind.

Deprecate SPIFFS, move examples to LittleFS (#7263)
* Deprecate SPIFFS, move examples to LittleFS

SPIFFS has been a great filesystem, but it has significant problems in
many cases (and it's also pretty slow).  Development seems to have
slowed/stopped on the upstream version, and we're not able to provide
support or fix the known issues with it as-is.

Deprecate SPIFFS variable.

Update all examples to use LittleFS instead of SPIFFS.

Also, minor cleanup on very old examples which has obsolete delays
waiting for the Serial port to come up, or which were stuck at 9600 baud
because of their ancient AVR heritage.

Fixes #7095

* Remove leftover debug code

* Clean up comments in some examples

* Update documentation on SPIFFS deprecation

* Fix host tests to avoid deprecation warnings

* Fix cut-n-paste error

* Restore SpeedTest.ino, adjust to allow custom FSes

Use F_CPU if (?) CPU frequency switch is compile-time only (#6833)
* At least the F_CPU define in host mock.h is needed by host Arduino.h - need to include Arduino.h further down in mock.h for this to work.

* Geting the include order right

* Prepare for runtime CPU clock rate selection

* Fix compile for not defined F_CPU

If defined F_CPU, make getCpuFreqMHz() a constexpr

* Use defines for register CPU2X instead of hex value

* Fix build for host - getCpuFreqMHz there was also in conflict with getCycleCount, using F_CPU:

tests/host/common/mock.h:#define F_CPU 80000000 (!)

* Asymmetrical includes and defines on host

* Support restart switch from 160MHz to 80MHz, e.g for OTA. Fixes #579

Fix Updater potential overflow, add host tests (#6954)
* Fix Updater potential overflow, add host tests

Fixes #4674

The Updater class could, when exactly 4K bytes were in the buffer but
not yet written to flash, allow overwriting data written to it beyond
the passed-in size parameter.

Fix per @jason-but's suggestion, and add a host test (plus minor changes
to Updater code to support host testing).

* Add missed mock file

* Remove most testing ifdefs fro updater

Per @mcspr's suggestion, we can pass in fake link symbols allowing
Updater to take the address of `_FS_start`/etc. even when building on
the host for testing.

There is still a single remaining wifi_set_power_mode ifdef'd and a
duplication of the digitalWrite/pinMode for testing vs. host building.

7036297920 Convert ESP8266WebServer* into templatized model (#5982)
* Convert ESP8266WebServer* into templatized model

Supercedes #4912

Refactor the three versions of ESP8266WebServer and *WebServerSecure to a
single templated class. Use "using" to enable old, non-templated names to b
used (so no user changes required to compile or run).

Fixes #4908 and clean up the code base a lot.

Basic tests run (the ones in the example code).

No code changes are required in userland except for setting the SSL
certificates which now use a cleaner "getServer()" accessor and lets the
app use the native BearSSL calls on the WiFiClientSecure object.

@devyte should be proud, it removes virtuals and even has template specialization...

* Fix HTTPUpdate templates and examples

* Fix HTTPUpdateServer library build

Need to remove dot-a linkage since there are no .cpp files in the
directory anymore due to templates.

* Provide backward-compat names for updt template

Allow existing code to use the same well known names for
HTTPUpdateSecure.

* Remove ClientType from all templates, auto-infer

Remove the ClientType template parameter from all objects.  Simplifies
the code and makes it more foolproof.

Add a "using" in each server to define the type of connection returned
by all servers, which is then used in the above templates automatically.

* Can safely include FS.h now that SD/SPIFFS unified

* Move the templates/objects to their own namespaces

* Fix merge issues with untemplated methods

* Address review comments

* Fix mock test, remove warnings inside test dir

Make the simple mock test CI job pass and clean up
any spurious warnings in the test directory.

There still are warnings in the libraries and core, but they
should be addressed in a separate PR.

a389a995fb Add LittleFS as an optional filesystem, API compatible w/SPIFFS (but not on-flash-format compatible) (#5511)
* Add LittleFS as internal flash filesystem

Adds a LittleFS object which uses the ARMmbed littlefs embedded filesystem,
https://github.com/ARMmbed/littlefs, to enable a new filesystem for onboard
flash utilizing the exact same API as the existing SPIFFS filesystem.

LittleFS is built for low memory systems that are subject to random power
losses, is actively supported by the ARMmbed community, supports directories,
and seems to be much faster in the large-ish read-mostly applications I use.

LittleFS, however, has a larger minimum file allocation unit and does not do
static wear levelling.  This means that for systems that need many little
files (<4K), have small SPIFFS areas (64K), or which have a large static
set of files covering the majority of flash coupled with a frequently
updated set of other files, it may not perform as well.

Simply replace SPIFFS.begin() with LittleFS.begin() in your sketch,
use LittleFS.open in place of SPIFFS.open to open files, and everything
else just works thanks to the magic of @igrr's File base class.

**LITTLEFS FLASH LAYOUT IS INCOMPATIBLE WITH SPIFFS**
Since it is a completely different filesystem, you will need to reformat
your flash (and lose any data therein) to use it. Tools to build the
flash filesystem and upload are at
https://github.com/earlephilhower/arduino-esp8266littlefs-plugin and
https://github.com/earlephilhower/mklittlefs/ .  The mklittlefs tool
is installed as part of the Arduino platform installation, automatically.

The included example shows a contrived read-mostly example and
demonstrates how the same calls work on either SPIFFS.* or LittleFS.*
Host tests are also included as part of CI.

Directories are fully supported in LittleFS. This means that LittleFS
will have a slight difference vs. SPIFFS when you use
LittleFS.openDir()/Dir.next().  On SPIFFS dir.next()
will return all filesystem entries, including ones in "subdirs"
(because in SPIFFS there are no subdirs and "/" is the same as any
other character in a filename).

On LittleFS, dir.next() will only return entries in the directory
specified, not subdirs.  So to list files in "/subdir/..." you need
to actually openDir("/subdir") and use Dir.next() to parse through
just those elements.  The returned filenames also only have the
filename returned, not full paths.  So on a FS with "/a/1", "/a/2"
when you do openDir("/a"); dir.next().getName(); you get "1" and "2"
and not "/a/1" and "/a/2" like in SPIFFS.  This is consistent with
POSIX ideas about reading directories and more natural for a FS.

Most code will not be affected by this, but if you depend on
openDir/Dir.next() you need to be aware of it.

Corresponding ::mkdir, ::rmdir, ::isDirectory, ::isFile,
::openNextFile, and ::rewind methods added to Filesystem objects.
Documentation has been updated with this and other LittleFS information.

Subdirectories are made silently when they do not exist when you
try and create a file in a subdir.  They are silently removed when
the last file in them is deleted.  This is consistent with what
SPIFFS does but is obviously not normal POSIX behavior.  Since there
has never been a "FS.mkdir()" method this is the only way to be
compatible with legacy SPIFFS code.

SPIFFS code has been refactored to pull out common flash_hal_* ops
and placed in its own namespace, like LittleFS.

* Fix up merge blank line issue

* Merge in the FSConfig changs from SDFS PR

Enable setConfig for LittleFS as well plys merge the SPIFFS changes
done in the SDFS PR.

* Fix merge errors

* Update to use v2-alpha branch

The V2-alpha branch supports small file optimizations which can help
increase the utilization of flash when small files are prevalent.
It also adds support for metadata, which means we can start adding
things like file creation times, if desired (not yet).

* V2 of littlefs is now in upstream/master

* Update test to support non-creation-ordered files

In a directory, the order in which "readNextFile()" will return a name
is undefined.  SPIFFS may return it in order, but LittleFS does not as
of V2.  Update the test to look for files by name when doing
readNextFile() testing.

* Fix LittleFS.truncate implementation

* Fix SDFS tests

SDFS, SPIFFS, and LittleFS now all share the same common set of tests,
greatly increasing the SDFS test coverage.

* Update to point to mklittlefs v2

Upgrade mklittlefs to V2 format support

* Remove extra FS::write(const char *s) method

This was removed in #5861 and erroneously re-introduced here.

* Minimize spurious differences from master

* Dramatically reduce memory usage

Reduce the program and read chunk sizes which impacts performance
minimally but reduces per-file RAM usage of 16KB to <1KB.

* Add @d-a-v's host emulation for LittleFS

* Fix SW Serial library version

* Fix free space reporting

Thanks to @TD-er for discovering the issue

* Update littlefs to latest upstream

* Remove sdfat version included by accident

* Update SDFAT to include MOCK changes required

* Update to include SD.h test of file append

add regular scheduled functions, now also callable on yield() (#6039)
* add regular scheduled functions, now also callable on `yield()`

added bool schedule_function_us(std::function<bool(void)> fn, uint32_t repeat_us)
lambda must return true to be not removed from the schedule function list
if repeat_us is 0, then the function is called only once.

Legacy schedule_function() is preserved

This addition allows network drivers like ethernet chips on lwIP to be regularly called
- even if some user code loops on receiving data without getting out from main loop
  (callable from yield())
- without the need to call the driver handling function
  (transparent)

This may be also applicable with common libraries (mDNS, Webserver, )

* polledTimeout: add option to use CPU count instead of millis()

* use more "using" alias

* more c++/clear code, using typename (thanks @devyte)

* rename class name to include unit, introduce timeMax() and check it with assert()

* remove useless defines

* improve api readability, add micro-second unit

* update example

* mock: emulate getCycleCount, add/fix polledTimeout CI test

* + nano-seconds, assert -> message, comments, host test

* allow 0 for timeout (enables immediate timeout, fix division by 0)

* typo, set member instead of local variable

* unify error message

* slight change on checkExpired() allows "never expired"
also removed printed message, add YieldAndDelay, simplify calculations

* remove traces of debug.h/cpp in this PR

* include missing <limits> header

* back to original expired test, introduce boolean _neverExpires, fix reset(), getTimeout() is invalid

* fix expiredOneShot with _timeout==0 check

* reenable getTimeout()

* expose checkExpired with unit conversion

* fix timing comments, move critical code to iram

* add member ::neverExpires and use it where relevant

* improve clarity

* remove exposed checkExpired(), adapt LEAmDNS with equivalent

* add API ::resetToNeverExpires(), use it in LEAmDNS

* remove offending constness from ::flagged() LEAmDNS (due do API fix in PolledTimeout)

* simplify "Fast" base classes

* minor variable rename

* Fix examples

* compliance with good c++ manners

* minor changes for consistency

* add missing const

* expired() and bool() moved to iram

* constexpr compensation computing
