* libu64

* logutils.o -> debug.o in spec

* stackcheck.c is part of libu64

* review

* add paragraph about Overlay_Load calling an external function

* audio code*

* [headers 13] osMalloc.h -> include/libc64/os_malloc.h

* also update the #includes :)

* Match __osMalloc

* Match src/code/code_800FC620.c (new/delete)

* Wrap versions-specific files in ifdefs to fix compilation

* Fix bss

* Remove {FAULT,RAND,OSMALLOC}_VERSION in favor of PLATFORM_N64

* Fix __osMalloc data splits, add unused strings

* __osMalloc.h -> osMalloc.h

* Fix merge

* Match stackcheck.c

* Match code_800FC620.c

* Make `sNew` in (unused) `code_800FC620.c` a string

It is passed as a filename to `__osMallocDebug` so should be a nul-terminated string, not a char[3] missing an explicit \0

* Fix gcc warning in `JpegDecoder_ParseNextSymbol` about SLL on negative value

-1U is an unsigned value, aka 0xFFFFFFFF
I keep -1 because it seems that's what a jpeg standard has too
