I was getting issues with __volatile__ for unknown reason, so moving
this to a dedicated file sidesteps the issue entirely and passes this
straight to GAS.
- Added wut_rules and wut/rpx/rpl.specs to share/
- Replaced wut's CMake-based buildsystem with a standard Makefile
- Conflated all wut libraries into a single libwut.a library
- wut's old buildsystems (CMake & plain make) are broken as a result,
this will be fixed in the future
- Docs, tests and samples are not buildable either at the moment
- wutcrt/wutnewlib:
- RPX start function is __rpx_start, while RPL is __rpl_start
- __init/fini_wut_* functions are no longer weak
- __init_wut/__fini_wut are instead weak
- Removed _exit implementation
- exit syscall now points to _Exit instead of pointing to itself
- wutstdc++:
- Renamed .cc files to .cpp
- Temporarily disabled, due to an issue that will be addressed shortly
- wutdevoptab:
- Fixed uninitialized variable warnings in __wut_fs_read/write
Move files to mem*heap.h.
Use MEMHeapHandle everywhere to reduce need for unecessary casts.
Rename types to match the function names better (e.g. Frame -> Frm).
