The Lua headers are needed because, yes, NetBSD has a kernel module for Lua
support. soundcard.h is technically a system header but is installed by
libossaudio and so was missed previously.
This also removes some riscv headers that shouldn't have been added because
NetBSD does not yet officially support the riscv32/riscv64 ports.
Closes#24737.
This defines a WinMain() function that can be potentially problematic when it
isn't wanted. If we add back support for this library in the future, it should
be built separately from mingw32.lib and on demand.
* libc: implement common `abs` for various integer sizes
* libc: move imaxabs to inttypes.zig and don't use cInclude
* libc: delete `fabs` c implementations because already implemented in compiler_rt
* libc: export functions depending on the target libc
Previously all the functions that were exported were handled equally,
though some may exist and some not inside the same file. Moving the
checks inside the file allows handling different functions differently
* remove empty ifs in inttypes

* sysident_assym.h was manually expanded.
* The ELF_NOTE_MARCH_DESC and ELF_NOTE_MARCH_DESCSZ macros will be defined
by the compiler.
* Legacy .init/.fini stuff was removed.
* GCJ nonsense was removed.
* NT_FREEBSD_ABI_TAG was manually adjusted from using a hardcoded value to using
__FreeBSD_version which will be defined by the compiler.
* GCJ stuff was removed.
* HAVE_CTORS definitions were removed.
* Introduce common `bzero` libc implementation.
* Update test name according to review

* address code review
- import common implementation when musl or wasi is included
- don't use `c_builtins`, use `@memset`
* bzero calling conv to .c
* Apply review

This lays the groundwork for #2879. This library will be built and linked when a
static libc is going to be linked into the compilation. Currently, that means
musl, wasi-libc, and MinGW-w64. As a demonstration, this commit removes the musl
C code for a few string functions and implements them in libzigc. This means
that those libzigc functions are now load-bearing for musl and wasi-libc.
Note that if a function has an implementation in compiler-rt already, libzigc
should not implement it. Instead, as we recently did for memcpy/memmove, we
should delete the libc copy and rely on the compiler-rt implementation.
I repurposed the existing "universal libc" code to do this. That code hadn't
seen development beyond basic string functions in years, and was only usable-ish
on freestanding. I think that if we want to seriously pursue the idea of Zig
providing a freestanding libc, we should do so only after defining clear goals
(and non-goals) for it. See also #22240 for a similar case.
