Move to c/darwin.zig as they really are libSystem/libc imports/wrappers.
As an added bonus, get rid of the nasty `usingnamespace`s which are now
unneeded.
Finally, add `os.ptrace` but currently only implemented on darwin.
The system linker shows warning when `msync` is linked instead of `__msync13`:
"warning: reference to compatibility msync(); include <sys/mman.h> for correct reference"
closes#14422
This allows for a more optimal std.crypto.tlcsprng codepath.
Without it a an "incorrect alignment" panic is triggered from
crypto.tlcsprng which aligns a threadlocal but it's actually
not aligned, thus detected by the safety check.
It appears that LLVM-IR does attribute the storage with alignment
but it is ultimately not respected in the final binary for netbsd
and dragonfly.
* 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.
