* pthread_key_t should also be available for non-android platforms
* Also change the type to c_uint because Linux pthreadtypes.h typedefs it as "unsigned int"
Partially addresses #13950
There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.
`sc_fpstate` member of `struct sigcontext` is a `struct fxsave64 *`.
use *anyopaque to represent it.
avoid to defining `fxsave64` as it is a packed struct with some arrays.
This makes `0123` and `u0123` etc. illegal.
I'm now confident that this is a good change because
I actually caught two C header translation mistakes in `haiku.zig` with this.
Clearly, `0123` being octal in C (TIL) can cause confusion, and we make this easier to read by
requiring `0o` as the prefix and now also disallowing leading zeroes in integers.
For consistency and because it looks weird, we disallow it for integer types too (e.g. `u0123`).

POSIX specifies that the sa_handler field of the sigaction struct may
be set to SIG_IGN or SIG_DFL. However, the current constants in the
standard library use the function pointer signature corresponding to
the sa_sigaction field instead.
This may not cause issues in practice because the fields usually occupy
the same memory in a union, but this isn't required by POSIX and there
may be systems we do not yet support that do this differently.
Fixing this also makes the Zig interface less confusing to use after
reading the man page.
This implementation uses the F_KINFO fcntl command added in FreeBSD
13 release. FreeBSD 12 users get a compile error.

alongside the typical msghdr struct, Zig has added a msghdr_const
type that can be used with sendmsg which allows const data to
be provided. I believe that data pointed to by the iov and control
fields in msghdr are also left unmodified, in which case they can
be marked const as well.
Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.

Currently, the new API will only be available on macOS with
the intention of adding more POSIX systems to it incrementally
(such as Linux, etc.).
Changes:
* add `posix_spawn` wrappers in a separate container in
`os/posix_spawn.zig`
* rewrite `ChildProcess.spawnPosix` using `posix_spawn` targeting macOS
as `ChildProcess.spawnMacos`
* introduce a `posix_spawn` specific `std.c.waitpid` wrapper which
does return an error in case the child process failed to exec - this
is required for any process that was spawned using `posix_spawn`
mechanism as, by definition, the errors returned by `posix_spawn`
routine cover only the `fork`-equivalent; `pre-exec()` and `exec()`
steps are covered by a catch-all error `ECHILD` returned by `waitpid`
on unsuccessful execution, e.g., no such file error, etc.
The libc interface uses `stat` instead of `stat64` struct.
This fixes, among other things, `zig fmt` accidentally setting the
formatted file's permission to 000.
