26ac7b3ff2 wutmalloc: Bugfixes, see details:
- Added (dummy) __init/fini_wut_malloc stubs called by wutcrt
  in order to ensure that wutmalloc gets linked in
- malloc/realloc/calloc now properly set errno to ENOMEM during failure
- realloc no longer fails if ptr==NULL (in this case it works
  like a regular malloc)
- realloc no longer does an out of bounds copy if the new size
  is smaller than the old size
- free(NULL) is now supported as per the C standard
- Disabled sbrk/malloc-lock support code in wutnewlib because
  newlib's malloc is replaced with wutmalloc

ee3bb10df4 First pass at adopting a devkitPro-style build system, see details:
- 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

98b6f6ec2f wutnewlib: Allow custom fixed sbrk heap size.
So now either uses 90% of the available base heap, or allocates a fixed
sized heap from the default heap.

1471ea4338 Change wutnewlib to implement malloc family of functions.
This allows us to forward them straight to default heap functions, this
is better than having to allocate a fixed heap for sbrk as it allows
people to better mix usage malloc & default heap functions.

d5effaaf88 coreinit: Cleanup memory heap functions.
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).

b4a6eb2f78 Split out crt from wutnewlib to wutcrt.
Can now optionally link newlib, stdc++, devoptab.

ac8a42fa7c Change to using new gthreads implementation.
Assuming that --enable-threads=dkp gets merged into devkitPPC r31... :)

37228a095d Disable call to __fini as it breaks stuff. 2018-05-26 18:18:16 +01:00

9a3cbcd2ef wutnewlib: Call __fini for global dtors.
main calls __eabi which calls __init, but main doesn't call __fini?
y u do this
