This is intended to be a more portable abstraction: rather than
hard-coding offsets in the macro invocations, it relies on the existence
of __builtin_offset and its availability even within inline asm blocks.
While here, rename some of the functions involved to hopefully improve
clarity
- 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
