* optionally move float emulation code into iram
allows doing float operation in iram
suitable for libraries like AccelStepper when called from ISR
* proposed changes for pio from @mcspr
* Resolve HWDT Reset with core_esp8266_vm
With the newer GCC compiler (after tag 3.0.2), example virtualmem was crashing with a HWDT reset.
Reordered some SPI register set lines in spi_init().
New ordering was based on ::begin in SPI.cpp
This change may resolve issues describe in
https://github.com/esp8266/Arduino/discussions/9010

spi_ctrl appears to need setting before other SPI registers

* A new approach for erasing WiFi Settings
Add support for hardware reset function call - simulates EXT_RST via HWDT.
Add reset selection to `ESP.eraseConfig()` for calling hardware reset
after erasing the WiFi Settings.
Update ArduinoOTA to use `ESP.eraseConfig(true)`
Externalized `ArduinoOTA.eraseConfigAndReset()`
Add OTA examples to illustrate using erase config changes.
* style
fixed confused example
* improve wording
* Add new state to retry eraseConfigAndReset
* Removed unreachable error test from examples.
Removed continuous retry of "eraseConfig" and allow the script to
assign an error handling option for "eraseConfig" failure.
Update example to use error handling option.
* In eboot for function ets_wdt_enable() added missing arguments
* Update comments and example
* Wording
* Rebuilt eboot.elf with current tools from ./get.py
* Requested changes.
* cleanup comments
* Update hardware_reset
Avoid using "[[noreturn]]" - not accepted for a .c file function
Updated to use __attribute__((noreturn)) to handle both .cpp and .c
file functions.
https://tls.mbed.org/ host does not support MFLN and Also Redirects the Client.
https://api.my-ip.io/ip is a better alternative, supporting MFLN and allowing the user to get a simple text with a useful information.
* Fixes occasional UMM_POISON failure
Bug introduced with PR fix#8914.
When a reallocated pointer could not grow in place, a replacement
allocation was created. Then UMM_POISON was written to the wrong block.
* Fix umm_poison data corruption on realloc when memory move is used.
Bug introduced with PR fix#8914
* refactored to resolve unused error in some build contexts
Fixes to recent changes to Postmortem to cover large jump offsets, use relaxed jump (J.L) in __wrap_system_restart_local.
Also add check that epc1 is a valid code address before reading.
* Add support WiFiClientSecure TCP KeepAlive
* Make TCP keepalive and related functions virtual.
* Make TCP keepalive and related functions override.
Fixes#8939
A popular method of handling an unrecoverable state is to reboot. The SDK does this in many places by printing a cryptic debug message followed by something equivalent to while(true){}, which compiles down to loop: j loop, creating a Soft WDT reset.
The umm_poison logic runs outside the UMM_CRITICAL_* umbrella. When interrupt routines do alloc calls, it is possible to interrupt an in-progress allocation just before the poison is set, with a new alloc request resulting in a false "poison check fail" against the in-progress allocation. The SDK does mallocs from ISRs.
SmartConfig can illustrate this issue, see
https://github.com/esp8266/Arduino/issues/3494#issue-247919259
Other Sketches built with Debug: "Serial," that use the SDK's Promiscuous callbacks are also likely to encounter problems.
The SDK support for "Promiscuous Receive" allocates memory from an ISR context, occasionally interrupting the poison wrapper code before it finishes setting the poison fences resulting in a false poison failed event.
No need to issue a MEMW instrunction per load from each cache line.
Only once after the last load is sufficient.
MEMW ensures that all previous load, store, acquire, release, prefetch,
and cache instructions perform before performing any subsequent load,
store, acquire, release, prefetch, or cache instructions.

* For SDK v3.0+, early system calls that were called from user_rf_pre_init
(SDK v2.2) need to now be called from user_pre_init.
Moved user_rf_pre_init() call to the end of user_pre_init() so we
can still perform early calls like: system_phy_set_rfoption(rf_mode),
system_phy_set_powerup_option(2), etc.
* Update comment
* Improve "spoof_init_data" enable/disable logic.
Out of an overabundance of caution, limit logic change to the
experimental SDK v3.0.5.
* httpclient: use refs - httpserver: add chunks in examples
* basic https client: update cert
* debug log: read() returning -1 is usual and means "nothing to read"
* emulation on host: SSL server has never been and is now working
* style
* move SSL server certs from examples into a single place with appropriate warnings
* web-hello-servers: make chunks bigger
* factorize template declaration
* http-client: add getString(pre-reservation)
* mock: add umm_info()
* style
* comment API in example
* style
* fix per review
* Update documentation
Describe how to improve Exception Decoder results.
Updated build option details.
* Added d-a-v's code. And updated description and debug macro.
* Update doc
Updated platform.txt - positioned -Os such that it can be overridden by `build.opt`.
Add suggestion of using `-Og` which may improve the Decoder's line number correlation
with the problem in the source code.
Untested adjustments to platformio-build.py
* Fixed code formatting
* Fixed example
Previously `-O3` in the example had no effect. It was overridden by later flags.
Reording the `-Os` allowed changing optimization to work. Somehow this triggered
a new warning "Stream.h:50:7: warning: 'f.Stream::_startMillis' may be used
uninitialized in this function". Replaced `-O3` with `-Og`.
* Proposed "Debug port" menu change
Preserves a pathway for `build.opt` override.
* Update boards.txt.py and docs - WIP
* Improve organization of optimization content.
Use "Debug Optimization" for menu name.
The menu item defines the initial optimization.
platform.txt - optimization parameter can be overridden by build.opt.
* Add fallback value for build.debug_optim to platform.txt
* update text and undo changes to platformio-build.py
* tweak text
* Added ':orphan:' mark to a06-global-build-options.rst
* Update doc. Added link in page index to 'Improving Exception Decoder Results'
* Update text to reference PR#8868 improvements for leaf function.
* Upcoming EspSoftwareSerial 7.0.1
* EspSoftwareSerial example: higher bitrates due to forcing half-duplex
* Adapt to SoftwareSerial's latest use of namespace.
* In EspSoftwareSerial, some renaming after review feedback.
* EspSoftwareSerial's use of a template class in order to permit users their own GPIO capabilities definitions.
* CI caught some warning.
* Stick to non-namespace EspSoftwareSerial class name for the moment.
* Delegate operator() is now nullptr-safe, good for use in ISRs.
* Pushed EspSoftwareSerial 8.0.1: Platformio picks up versions that aren't published in Github
It's trivial to run into a problem caused by the single hardware breakpoint
limitation, but the existing documentation doesn't explicitly address this
situation (and search results for the error message aren't particularly
helpful).
This commit updates the documentation with an explicit example of what
happens when a breakpoint expression matches multiple locations, along with
a possible workaround.
The assignment done in FLASH_MAP_SETUP_CONFIG_ATTR did not apply the attribute to __flashdesc,
and made it impossible to override it with FLASH_MAP_SETUP_CONFIG.
Moved up os.makedirs for ./core/ directory.
Strange problem creating files with file paths with spaces.
Strange that "create file" would work when the path did not contain spaces and the last folder of the path hadn't been created.
Added try/except on main to commit print buffer on traceback for context.
Additional issues with diacritics and locale character encoding for shell vs source code.
build.opt is written with the same encoding as the shell; however, the data read from the Sketch.ino.global.h is UTF-8.
Tested on Windows 10 (en-US) with Arduino IDE 2.0.3 Under an
account with a diacritic character in the user ID path.
Needs testing on Japanese Windows
* divide by 0 reporting to point back at the divide function caller
* stack offset adjustments to be independent of __wrap_system_restart_local()'s stack frame size.
* re-use SdFat access mode through static const, no need to hard-code our own value w/ cast in the macro
* separate read-modes from flags; read, write and rw are distinct numbers
* simple compile-time tests in .cpp
