Clean up uploader.py, use implied paths (#5805)
No need to explicitly send in full paths for esptool and pyserial Python
libs because they're in well known locations relative to upload.py.

Make upload.py calculate these on-the-fly and clean up platform.txt.

Use Pythonic way of calling esptool, avoid fork(#5797)
Simply import the pyserial and esptool modules directly into upload.py
instead of trying to fake things with os.fork()s.  Reduces code and is
more Pythonic.

Revert to nonos-sdk 2.2.1, new sdk-switching option in IDE menu for generic board only (#5763)
This commit allows switching SDK firmware:

nonos-sdk-pre-v3 shipped with release 2.5.0 has issues:

    * Some boards show erratic behavior (radio connection is quickly lost), with an unknown cause.
      These boards work well with previous nonos-sdk-2.2.1 firmware (#5736)

    * Overall performances seem to have decreased (#5513)

This PR restores sdk2.2.1 (as in core-2.4.2).

SDK-pre-3.0 - which has brought long awaited fixes (WiFi sleep modes) - is still available through a menu option available only with generic board.

BREAKING

    * new define `-DNONOSDK221=1` or `-DNONOSDK3V0=1`

    * for external build systems: new library directory: `tools/sdk/lib/<version>/lib`

    * PIO: variable `PIO_FRAMEWORK_ARDUINO_ESPRESSIF_SDK3` is needed for sdk-pre-v3.


Fix #5736

9790e1cb7c Use esptool.py to handle sketch upload, make python available on Windows, too (#5635)
* Add esptool.py, pyserial, and python to JSON

Add installation of python on Win32/Win64, and on all systems install
esptool.py and pyserial.

* Initial esptool.py upload test

* First successfull esptool.py upload

* Patch in verbose flag operation

* Replace esptool-ck.exe with Python equivalent

Remove need for binary esptool-ck.exe by implementing the same logic as
esptool-ck uses in Python.  Only image creation is supported, and only
in the Arduino standard mode (with its custom bootloader and ROM
layout).

* Remove all esptool-ck.exe, hook Windows Python

Remove all references to esptool-ck and use Python on Windows and Linux
for all recipes where possible.

* Use python to make core_version as well

Avoid ugly bash and CMD.exe tricks in platform.txt by using python to
make the core_version header.

* Rename conflicting script, clean up packager

* Windows test passes

Need to make sure Python2 and Python3 compatible and paths are munged
properly to avoid eaccidentally escaping things when calling esptool.py

Able to compile, build a BIN and upload via esptool.py on a Windows
machine without Python installed globally, only as part of the Arduino
tools package.

* Use github sources for pyserial

* Erase calibration or all flash before programming

Add back in erase support by calling esptool.py twice (since it does not
support chained operations like esptool-ck.exe).

* Make 460K default speed, remove 961K

961K doesn't seem to work with esptool, so make 460K the default upload
speed and remove 961K.

Even at this lower speed, esptool.py is much faster to upload (even
before taking into account the compression when doing things like SPIFFS
and code upload).

* Make erase and upload work again

Arduino does not support a upload.#.cmd pattern, so we need to do
everything in a single command line.  Make it cleaner by introducing a
Python wrapper script which will run the same executable with different
sets of commands (since we need to erase a block w/a separate invocation
from the real upload).

Update boards.txt to use the new options format, placing the esptool
command as "version" when there is no "erase_flash" or "erase_region" to
be done to keep things simple.

* Move esptool/pyserial to submodules

Since esptool.py and pyserial are coming directly from github repos,
there is no need to include them as a tool in package.json.

* Restore 921K upload opt, silent downgrade to 460k

To enable full backward compatibility, restore the 921k option for
upload speed but silently change it to 460k in the upload.py script.

Add error checking on upload.py

68f5a3d0d3 Keep signing commands in platform.txt on release (#5491)
* Keep signing commands in platform.txt on release

The boards packager was deleting what was at the time it was written
unused lines in fht platform.txt file before deploying to Arduino.
One of these lines is now needed for signing to work, so don't delete
it.

Also, explicitly call "python signing.py" because it looks like Arduino
is sanitizing/removing executable bits on files when extracting from
boards manager installations.

Fixes #5483

* Create the build subdir, if needed, for autosign

If the temporary build/core directory isn't available, make it in order
that Updater.cpp will see the generated signing header and not the one

6280e98b03 Enable exceptions, update to optimized newlib, migrate to new toolchain (#5376)
* Move to PROGMEM aware libc, allow PSTR in printf()

A Newlib (libc) patch is in progress to move the _P functions from inside
Arduino into first-class citizens in libc.  This Arduino patch cleans up
code that's been migrated there.  Binaries for the new libs are included
because it seems they're part of the Arduino git tree, and should be
replaced with @igrr built ones when/if the Newlib changes are accepted.

Notable changes/additions for Arduino:
Allow for use of PROGMEM based format and parameter strings in all
*printf functions.  No need for copying PSTR()s into RAM before printing
them out (transparently saves heap space when using _P functions) and
makes it easier to print out constant strings for applications.

Add "%S" (capital-S) format that I've been told, but cannot verify,
is used in Arduino to specify a PROGMEM string parameter in printfs,
as an alias for "%s" since plain "%s" can now handle PROGMEM.

Optimized the memcpy_P, strnlen_P, and strncpy_P functions to use 32-bit
direct reads whenver possible (source and dest alignment mediated), but
there is still room for improvement in others.

Finally, move several constant arrays from RODATA into PROGMEM and
update their accessors.  Among these are the ctype array, ~260 bytes,
mprec* arrays, ~300 bytes, and strings/daycounts in the time
formatting functions, ~200 bytes.  All told, sketches will see from
300 to 800 additional RAM heap free on startup (depending on their
use of these routines).

* Fix merge error in #ifdef/#endif

* Fix host test using the newlib generic pgmspace.h

Host tests now use the sys/pgmspace.h for compiles instead of the
ESP8266-specific version.

* Update with rebuilt libraries using latest newlib

* Include binaries built directly from @igrr repo

Rebuild the binaries using a git clone of
https://github.com/igrr/newlib-xtensa

* Fix merge define conflict in c_types.h

* Fix strlen_P misaligned source error

Include fix from newlib-xtensa/fix-strlen branch cleaning up misaligned
access on a non-aligned source string.

* Fix strlen_P and strcpy_P edge cases

Ran the included test suite on ESP8266 tstring.c with the following defines:
 #define MAX_1 50
 #define memcmp memcmp_P
 #define memcpy memcpy_P
 #define memmem memmem_P
 #define memchr memchr_P
 #define strcat strcat_P
 #define strncat strncat_P
 #define strcpy strcpy_P
 #define strlen strlen_P
 #define strnlen strnlen_P
 #define strcmp strcmp_P
 #define strncmp strncmp_P

Uncovered edge case and return value problems in the optimized versions of
the strnlen_P and strncpy_P functions.  Corrected.

* Fix memcpy_P return value

memcpy-1.c test suite showed error in return value of memcpy_P.  Correct it.

* Fix strnlen_P/strlen_P off-by-4 error

Random crashes, often on String constructors using a PSTR, would occur due
to the accelerated strnlen_P going past the end of the string. Would make
debug builds fail, too (ESP.getVersionString() failure).

Fix to fall through to normal copy on a word that's got a 0 byte anywhere
in it.

* Add device tests for libc functional verification

Add test suite used to debug libc optimized _P functions to the device
tests.

* Rebuild from igrr's repo (same source as prior)

Rebuild .a from igrr's repo at 347260af117b4177389e69fd4d04169b11d87a97

* WIP - add exceptions

* Fix exception to have 0-terminator

* Move some exception constants to TEXT from RODATA

* Remove throw stubs

* Move more exception stuff to ROM

* Enable exceptions in platform.io

* Remove atexit, is duplicated in rebuilt lib

Need to look at the quick-toolchain options, there seems to be a definition
for atexit defined there (libgcc?) that needs to be excised.  For now,
remove our local do-nothing copy.

* Update libgcc to remove soft-fp functions

The esp-quick-toolchain generated libgcc.a needed to have the soft-FP routines
that are in ROM removed from it.  Remove them in the new esp-quick-toolchain
and update.

* Fix merge typos in Makefile

* Add unhandled exception handler to postmortem

* Return our atexit() handler

* Latest stdc++, minimize exception emercengy area

* Remove atexit from newlib

atexit was defined in newlib strongly, but we also define a noop atexit in core.
Since we never exit, use the core's noop and delete the atexit from libc.a

Updated in esp-quick-toolchain as well.

* Move __FUNCTION__ static strings to PROGMEM

__FUNCTION__ is unlikely to be a timing sensitive variable, so move it to
PROGMEM and not RODATA (RAM) using linker magic.

asserts() now should take no RAM for any strings.

* Clean up linker file, update to latest stdc++

* Update to latest stdc++ which doesn't call strerror

* Update to GCC5.1 exception emergency allocator

Using GCC 5.1's emergency memory allocator for exceptions, much less
space is required in programs which do not use exceptions and when
space is allocated it is managed more efficiently.

* Initial try with new compiler toolchain

* Include newlib built from esp-quick-toolchain

* Update JSON with all new esp-quick-toolchain builds

* Use 64bit Windows compiler on 64bit Windows

* Dump std::exception.what() when possible

When doing the panic on unhandled exceptions, try and grab the
.what() pointer and dump it as part of the termination info.
Makes it easy to see mem errors (std::bad_alloc) or std::runtime_error
strings.

* Use scripted install from esp-quick-toolchain

Makes sure proper libraries and includes are present by using a
scripted installation from esp-quick-install instead of a manual
one.

* Update eqk to remove atexit, fix packaging diff

Add cryptographically signed update support (#5213)
Using a pluggable architecture, allow updates delivered via the Update
class to be verified as signed by a certificate.  By using plugins, avoid
pulling either axTLS or BearSSL into normal builds.

A signature is appended to a binary image, followed by the size of the
signature as a 32-bit int.  The updater takes a verification function
and checks this signature using whatever method it chooses, and if it
fails the update is not applied.

A SHA256 hash class is presently implemented for the signing hash (since
MD5 is a busted algorithm).

A BearSSLPublicKey based verifier is implemented for RSA keys.  The
application only needs the Public Key, while to sign you can use
OpenSSL and your private key (which should never leave your control
or be deployed on any endpoints).

An example using automatic signing is included.

Update the docs to show the signing steps and how to use it in the
automatic and manual modes.

Also remove one debugging line from the signing tool.

Saves ~600 bytes when in debug mode by moving strings to PMEM

Windows can't run the signing script, nor does it normally have OpenSSL
installed.  When trying to build an automatically signed binary, warn
and don't run the python.

38779149d0 Move ICACHE_* to unique sections, local LD script (#5150)
* Move ICACHE_* to unique sections, local LD script

Similar to PROGMEM changes, make the name of each ICACHE_* variable/fuction
unique to avoid issues with section conflicts.

Also rename the generated LD linker script to avoid issue with older copies
of the eagle.app.v6.common.ld which were generated by the build process
in a global directory before being moved to the {build.path}.  The linker
would use the older, generated *.ld file instead of the generated one, which
would lead to runtime failures on some systems and cause the VTABLE location
to not correspond to the IDE menu selection.

Fixes #5115, and is an update to #5117 and #5116.

package: add version to board package name (#5046)
In tools menu, boards belonging to each platform are grouped together.
The title of the groups is the board package name. When switching
between versions, mentioning the version number in package name helps
identify the installed version.

Rename board group from "ESP8266 Modules" to "ESP8266 Boards", to be
more similar to other platforms, and to reflect the fact that most
entries included are boards, not modules.

As an extra change, when building the boards manager package, set
version number in platform.txt based on git tag name. This saves one
step when creating the release — don't need to update platform.txt
twice.

Add BearSSL client and server, support true bidir, lower memory, modern SSL (#4273)
BearSSL (https://www.bearssl.org) is a TLS(SSL) library written by
Thomas Pornin that is optimized for lower-memory embedded systems
like the ESP8266. It supports a wide variety of modern ciphers and
is unique in that it doesn't perform any memory allocations during
operation (which is the unfortunate bane of the current axTLS).

BearSSL is also absolutely focused on security and by default performs
all its security checks on x.509 certificates during the connection
phase (but if you want to be insecure and dangerous, that's possible
too).

While it does support unidirectional SSL buffers, like axTLS,
as implemented the ESP8266 wrappers only support bidirectional
buffers. These bidirectional buffers avoid deadlocks in protocols
which don't have well separated receive and transmit periods.

This patch adds several classes which allow connecting to TLS servers
using this library in almost the same way as axTLS:
BearSSL::WiFiClientSecure - WiFiClient that supports TLS
BearSSL::WiFiServerSecure - WiFiServer supporting TLS and client certs

It also introduces objects for PEM/DER encoded keys and certificates:
BearSSLX509List - x.509 Certificate (list) for general use
BearSSLPrivateKey - RSA or EC private key
BearSSLPublicKey - RSA or EC public key (i.e. from a public website)

Finally, it adds a Certificate Authority store object which lets
BearSSL access a set of trusted CA certificates on SPIFFS to allow it
to verify the identity of any remote site on the Internet, without
requiring RAM except for the single matching certificate.
CertStoreSPIFFSBearSSL - Certificate store utility

Client certificates are supported for the BearSSL::WiFiClientSecure, and
what's more the BearSSL::WiFiServerSecure can also *require* remote clients
to have a trusted certificate signed by a specific CA (or yourself with
self-signing CAs).

Maximum Fragment Length Negotiation probing and usage are supported, but
be aware that most sites on the Internet don't support it yet.  When
available, you can reduce the memory footprint of the SSL client or server
dramatically (i.e. down to 2-8KB vs. the ~22KB required for a full 16K
receive fragment and 512b send fragment).  You can also manually set a
smaller fragment size and guarantee at your protocol level all data will
fit within it.

Examples are included to show the usage of these new features.

axTLS has been moved to its own namespace, "axtls".  A default "using"
clause allows existing apps to run using axTLS without any changes.

The BearSSL::WiFi{client,server}Secure implements the axTLS
client/server API which lets many end user applications take advantage
of BearSSL with few or no changes.

The BearSSL static library used presently is stored at
https://github.com/earlephilhower/bearssl-esp8266 and can be built
using the standard ESP8266 toolchain.

f2c7256539 Add flash for vtable destination, make it default, and add build menu to control options (#4582)
* Add flash for vtable destination, make it default

Add an option for placing vtables in flash to complement the existing
iram and heap options.  "make flash"

Now that there is a way to change it, move to vtables in flash as default
as only users with interrupts which use vtables require the vtable to
be in RAM.  For those users, if the tables are small enough they can put
them in IRAM and save heap space for their app.  If not, then the vtables
can be placed in HEAP which supports much larger tables.

* Add VTable menu, FLASH as default, remove Makefile

Convert from manual "make" operated app.ld creation to runtime creation
whose options are selected from the build menu.

Use a prelink recipe to create the output app.ld file each run, without
need for any special tools.

ae13809c81 Update SDK to 2.0.0
- Update SDK header files and libraries to SDK 2.0.0 plus 2.0.0_16_08_09
  patch
- Remove mem_manager.o from libmain.a (replaced with umm_malloc)
- Disable switch from DIO to QIO mode for certain flash chips (saves
  IRAM space)
- Add user_rf_cal_sector_set; it points to rf_init_data sector.
- Change the way rf_init_data is spoofed.
  This is now done by wrapping spi_flash_read and returning the data we
  need during startup sequence.
- Place lwip library into flash using linker script instead of section
  attributes (saves IRAM space)

d7d98d03ca Use libc from newlib (#1752)
* Use newlib libc library

This change adds libcmin.a, which is created from newlib libc by selectively removing some of the object files (mostly related to heap management).
The list of files is available in tools/sdk/lib/make_libcmin.sh. Files which are not needed are commented out.
This change adds support for various functions which were missing, like sscanf, strftime, etc.

* Fix some of the time functions

* Redirect stdout to serial

* Implement __putc_r

* Switch to custom newlib build
