This commit and, by extension, PR attempts to update `stb` in the most
straightforward way possible as well as include fixes from main repo's
unmerged PRs for cases rearing their ugly heads during everyday usage:
- stb#1299: stb_rect_pack: Make rect_height_compare a stable sort
- stb#1402: stb_image: Fix "unused invalid_chunk" with STBI_FAILURE_USERMSG
- stb#1404: stb_image: Fix gif two_back memory address
- stb#1420: stb_image: Improve error reporting if file operations fail
within *_from_file functions
- stb#1445: stb_vorbis: Few static analyzers fixes
- stb#1487: stb_vorbis: Fix residue classdata bounding for
f->temp_memory_required
- stb#1490: stb_vorbis: Fix broken clamp in codebook_decode_deinterleave_repeat
- stb#1496: stb_image: Fix pnm only build
- stb#1497: stb_image: Fix memory leaks if stbi__convert failed
- stb#1498: stb_vorbis: Fix memory leaks in stb_vorbis
- stb#1499: stb_vorbis: Minor change to prevent the undefined behavior -
left shift of a negative value
- stb#1500: stb_vorbis: Fix signed integer overflow
Includes additional small fixes that I felt didn't warrant a separate PR.
- Use good ELF technique in cosmo_dlopen()
- Make strerror() conform more to other libc impls
- Introduce __clear_cache() and use it in cosmo_dlopen()
- Remove libc/fmt/fmt.h header (trying to kill off LIBC_FMT)
This change integrates e58abc1110b335a3341e8ad5821ad8e3880d9bb2 from
https://github.com/ahgamut/musl-cross-make/ which fixes the issues we
were having with our C language extension for symbolic constants. This
change also performs some code cleanup and bug fixes to getaddrinfo().
It's now possible to compile projects like ncurses, readline and python
without needing to patch anything upstream, except maybe a line or two.
Pretty soon it should be possible to build a Linux distro on Cosmo.
I wanted a tiny scriptable meltdown proof way to run userspace programs
and visualize how program execution impacts memory. It helps to explain
how things like Actually Portable Executable works. It can show you how
the GCC generated code is going about manipulating matrices and more. I
didn't feel fully comfortable with Qemu and Bochs because I'm not smart
enough to understand them. I wanted something like gVisor but with much
stronger levels of assurances. I wanted a single binary that'll run, on
all major operating systems with an embedded GPL barrier ZIP filesystem
that is tiny enough to transpile to JavaScript and run in browsers too.
