Discovered over on the dev-esp32-idf4 branch.
- Off by one error in loadLFS, leading to slight memory leak and
potential corruption.
- Insufficient return value check in loadLFS, where uzlib may return
one of two success conditions, one of which would result in an
out-of-bounds access and related pain.
- One case of a side effect within a lua_assert(), leading to
silently broken LFS image handling when compiling without asserts
enabled, the issue showing up as module names being shuffled around.
- Incorrect encoding of TValues in LFS when 64bit numbers in use.
- Lots of minor but nasty bugfixes to get all tests to run clean
- core lua and test suite fixes to allow luac -F to run cleanly against test suite
- next tranch to get LFS working
- luac.cross -a options plus fixes from feedback
- UART fixes and lua.c merge
- commit of wip prior to rebaselining against current dev
- more tweaks
