- check in cont_run() and cont_suspend() whether a1 is out of bounds
- in case a1 is broken, postmortem will still report proper context in
proper stack boundaries
additionally
- as suggested in #9069, change stack smashing to a single line that
does not mention any Exceptions
- reduce overall stack dump length when there are know garbage values i.e. cont stackguard
- decoder.py addr search regexp would no longer skip stack lines with '<'
- fix decoder.py parsing so it notices both stack smashing and alloc errors
* stack decoder
* +x
* cut here
* last alloc explain, line breaks
* capture
* print ctx line
* ...and dont ignore sp
* non-hyphenated arg for elf, toolchain path to bin/
either for when tools are already in PATH
or, using `pio pkg exec --package toolchain-xtensa python decoder.py ...`
(where package is a full version spec for pio registry)
