Commit 891eb3b0 was fixing an issue with PS and EPC1 not being
preserved after the window spill procedure. It did so by saving PS in
a2 and EPC1 in a4. However the a4 register may be a live register of
another window in the call stack, and if it is overwritten and then
spilled to the stack, then the corresponding register value will end
up being corrupted. In practice the problem would show up as an
IllegalInstruction exception, when trying to return from a function
when a0 value was 0x40020.
Fix by using a0 register instead of a4 as scratch. Also fix a comment
about xthal_save_extra_nw, as this function in fact doesn't clobber
a4 or a5 because XCHAL_NCP_NUM_ATMPS is defined as 1.

Can still be enabled by passing --cmake-warn-uninitialized on the command line
Prevents CMake warnings printed by default if IDF_PATH is underneath the CMake
project directory.
The reason for this is that CMake --warn-uninitialized only enables checks
inside the project directory (ie top-level CMakeLists.txt directory and
subdirectories), it doesn't enable for files included from other directories.
(The only way to enable warnings in other directories is to pass
--check-system-dirs and this looks like it's only useful for CMake's own
developers as it prints a lot of warnings from inside CMake otherwise - see
https://gitlab.kitware.com/cmake/cmake/-/issues/19645 )
Plan to follow up with a later commit to clean up most of the warnings (which
aren't problems for CMake execution), but we'll also disable this option by
default to avoid this unexpected triggering of IDF warnings.
Due to eager_exclude, Sphinx jobs cannot use the doc cache (doctrees).
PDF and HTML building are now seperate CI jobs to avoid this issue.
PDF building will only be ran on deploy branches and when started
with build_docs tag to reduce CI load
1. Add g_av_with_rc to avrc_tg_init function
2. Remove g_av_open_fail
3. Add comment in API files
4. Add a2dp init & deinit state variable to inidcate a2dp statement
1. Add reaction for a2dp snk & src disconn req when no link up
2. Change state machine set before EVT upto APP layer in some cases
3. Add bool open_fail to choose whether post disconnection evt to app layer
Fixup more for PSRAM issue;
Allow GDB work correctly with Privileged Registers;
Based on GCC 8.4.0;
Update a fix of C++ exception crashs from the GCC mainline;
Fixup strptime_l() and some locale in libc;
If Secure Boot is enabled, there's no bootloader flasher arguments in the
project (to encourage careful manual flashing), so this command would
fail with a KeyError.
Per WiFi library requirement, SSID can be non-null terminated string
if its length goes to 32 bytes (maximum). Use of strncpy in this case,
along with compiler optimization level -O2 results in some warnings
for potential use of non-null terminated strings.
Fix here ensures use of memcpy to copy SSID string upto appropriate
desired length. This helps to avoid compiler specific workaround
flags added earlier.
