Wire everything that relies on stack smashing detection to call
`__stack_chk_fail()` (aka what libssp / ssp / stack-protector uses)
Expose it in our debugging header
Rename overflow -> smashing, as these are different things we are trying
to detect (meaning, that we check for things writing there, not some
kind of `alloca` issue or the way `-fstack-check` would have worked)
ref. #8666
`-fstack-protector` continues to work as it always did
CONT replaces `abort()`, also moves its check to the loop wrapper to
avoid dumping otherwise useless SYS context memory
StackThunk replaces a similar `abort()` call
Create dedicated function for xPortGetFreeHeapSize() that only reports on DRAM.
NONOS SDK API system_get_free_heap_size() relies on xPortGetFreeHeapSize() for the free Heap size.
Possible breaking change for multiple Heap Sketches calling system_get_free_heap_size(); it will now always report free DRAM Heap size.
Update and export umm_free_heap_size_lw() to report the free Heap size of the current Heap.
Updated ESP.getFreeHeap() to use umm_free_heap_size_lw().
Updated build options to supply exported umm_free_heap_size_lw() via either UMM_STATS or UMM_INFO.
Improved build option support via the SketchName.ino.globals.h method for Heap options: UMM_INFO, UMM_INLINE_METRICS, UMM_STATS, UMM_STATS_FULL, UMM_BEST_FIT, and UMM_FIRST_FIT. While uncommon to change from the defaults, you can review umm_malloc_cfgport.h for more details, which may help reduce your Sketch's size in dire situations. Assuming you are willing to give up some functionality.
For debugging UMM_STATS_FULL can offer additional stats, like Heap low water mark (umm_free_heap_size_min()).
The NONOS SDK's `struct bss_info` in `user_interface.h` has grown since the
beginning of this project. The additional elements are not accessible.
Add a method for R/O access to full `struct bss_info`.
See #7965 (comment)
Amends #8507
I took the liberty to also do some refactoring; specifically, fixing signed vs. unsigned mismatch in len, using pointer object vs. the original manual malloc & free, try to have named constants for certain addresses and lengths, plus localize printing of u8 arrays.
The suggested test to have a 'dummy' verifier works just fine. (...how it actually works and gets the hash to compare with is a whole other question, though)
Another issue noticed while testing, in the underlying bearssl api there's an actual limit for hash length.

* make WiFi/Ethernet interface compatible with Arduino Ethernet API
provide some minimaly adapted examples from legacy
* move ethernet compat globals to EthernetCompat.h
* LegacyEthernet: add UDP example
* adjust comments

* Board ID as build flag
When using IDE or `arduino-cli board list`, show full board name and FQBN
```
$ arduino-cli.exe board list
Port Protocol Type Board Name FQBN Core
xxx.xxx.x.xxx network Network Port LOLIN(WEMOS) D1 R2 & mini esp8266com:esp8266:d1_mini esp8266com:esp8266
```
Also add `description` field to the mDNS response containing the
original `{build.board}` string value.

Separate page handling logic and the actual writing. Make sure we place both unaligned src and dest into a buffer.
Fixes edge-case introduced for SPIFFS that exclusively works through unaligned flash write function.
This copies the behaviour of official RTOS port, but does not change the original spi_flash_write.
Update soon-to-be deprecated code in the runner.py
https://docs.python.org/3/library/imp.html is deprecated since 3.4, will be removed in 3.12
https://docs.python.org/3/library/configparser.html readfp() is replaced with read_file() since 3.2, will be removed in 3.12
Use venv instead of virtualenv. We don't really use any of the extended features, and might as well simplify installation requirements.
virtualenv/bin/python can execute runner.py inside of venv, no need to activate beforehand.
* Fix sending NACK, use helper function to fill pbuf
As noticed in https://github.com/esp8266/Arduino/pull/8582#issuecomment-1153331408
Plus, handle the case when `pbuf->len` is less than struct size
* Make sure to call SDK functions to start and stop DHCP server
As noticed in https://github.com/esp8266/Arduino/pull/8582#issuecomment-1153331408
Can't really use `server.begin()` and `server.end()` directly, only
default static IP is applied to the interface since DHCP server is
deemed 'running' (see `wifi_softap_dhcps_status()` return value)

* Add FSTools with examples of how to convert between SPIFFS and LITTLEFS.
* Oops. Need to pass layout by reference in order to capture the correct address. Took a while to find that. There maybe a better way to store all these configs
* Update FSTools.cpp
fix ESP.h to Esp.h
* Fix unused variable i
* Parsed with restyle.sh. Compile with all errors.
* remove unused variable
* fix different sign complication error
* Fix indentation to spaces
Run test/restyle.sh
Remove commented code
Use #ifdef blocks for debugging. `DEBUG_ESP_CORE` and `DEBUG_ESP_PORT`
use `static constexpr layout` which saves ROM ~500B for unused vars
* Update FSTools.cpp
Add yield in between file copy
* works
* fixup! works
* back to callbacks
* names
* daisy chain
* seconds
* less inline
* fix dns setter
* might as well keep using initlist
/to d-a-v it has automatic storage, here it's the same stack based one
(just one less line for us)
* shift blame
* naming
* fix impl
* revert to ip4 dns
* merge fix
* restyle
* masking done wrong
* Patch eap.o memory leak
WiFi Enterprise option can leak up to 3 allocations per connect/disconnect
cycle: anonymous Identity, password, and some unidentified allocation.
This solution patches eap.o from libwpa2 to call a special 2 part
wrapper instead of vPortFree for cleanup.
Corrected typos and adjusted tabs in script.
Added script eval_fix_sdks.sh to aid in evaluating similarity between
patch sections of .o files being patched across different SDKs.
* Add some dev debug code and improve comments

Fixes: #8082
This patches the callx0 instruction to a nop in eap.o which is part of libwpa2.a.
It looks like espressif fixed the Bug in newer SDK versions, so if we update to the latest NONOS-SDK it is most likely not necessary to add/adapt this patch.
Also modifies the fix_sdk_libs.sh script as it even changed files if no changes were necessary, for example adding multiple system_func1 exports.
* Apply suggestions from code review
* Initialize SoftAP DhcpServer object on demand
Remove dependency on global ctor, and just construct the object when
someone asks us to do it. Only dependency right now is netif_git, which
is expected to be initialized by the lwip code some time before
dhcps_start happens.
Removing ip_info from begin(), since we never reference later on.
Also removing the specific check for netif id and simplify the ctors.
Update tests and recover old nonos-sdk dhcps functions that were not implemented.
* nonos helpers have a separate header
* wifi ap needs this anyway, simplify sketch includes
* missing example
* existing name :/
* trying to fix header dependency
* restyle
* not a c header
* no need to init
* move dhcp server getter to WiFi
more... arduino'ish? we ahve object as namespace, plus everything else
related to softAP is there
redundant includes, redundant mock impl (out-of-scope here to fix)
* ...move things back, still expose as WiFi method
* review fix
* include -nonos header in wifi lib though
* no more lwip include
* style
* need mock dhcpserver instance
