According to https://en.cppreference.com/mwiki/index.php?title=c/locale/setlocale&oldid=171500 ,
`setlocale` "returns null value on failure":
> Return value
> pointer to a narrow null-terminated string identifying the C locale
> after applying the changes, if any, or null pointer on failure.
Example program:
```zig
const std = @import("std");
pub fn main() void {
const ptr = std.c.setlocale(.ALL, "non_existent");
std.debug.print("ptr = {d}\n", .{@intFromPtr(ptr)});
}
```
Output:
```console
ptr = 0
```

Thanks to Zig's lazy analysis, it's fine for these symbols to be
declared on platform they won't exist on. This is already done in
several places in this file; e.g. `pthread` functions are declared
unconditionally.
Eliminates one more usage of `usingnamespace` from the standard library.
4 remain.
* std.c: consolidate some definitions, making them share code. For
example, freebsd, dragonfly, and openbsd can all share the same
`pthread_mutex_t` definition.
* add type safety to std.c.O
- this caught a bug where mode flags were incorrectly passed as the
open flags.
* 3 fewer uses of usingnamespace keyword
* as per convention, remove purposeless field prefixes from struct field
names even if they have those prefixes in the corresponding C code.
* fix incorrect wasi libc Stat definition
* remove C definitions from incorrectly being in std.os.wasi
* make std.os.wasi definitions type safe
* go through wasi native APIs even when linking libc because the libc
APIs are problematic and wasteful
* don't expose WASI definitions in std.posix
* remove std.os.wasi.rights_t.ALL: this is a footgun. should it be all
future rights too? or only all current rights known? both are
the wrong answer.
- Adds `illumos` to the `Target.Os.Tag` enum. A new function,
`isSolarish` has been added that returns true if the tag is either
Solaris or Illumos. This matches the naming convention found in Rust's
`libc` crate[1].
- Add the tag wherever `.solaris` is being checked against.
- Check for the C pre-processor macro `__illumos__` in CMake to set the
proper target tuple. Illumos distros patch their compilers to have
this in the "built-in" set (verified with `echo | cc -dM -E -`).
Alternatively you could check the output of `uname -o`.
Right now, both Solaris and Illumos import from `c/solaris.zig`. In the
future it may be worth putting the shared ABI bits in a base file, and
mixing that in with specific `c/solaris.zig`/`c/illumos.zig` files.

I have updated Felix's ZigAndroidTemplate to work with the latest
version of Zig and we are exploring adding Android support to Mach engine.
`std.c.getcontext` is _referenced_ but not _used_, and Android's bionic libc
does not implement `getcontext`. `std.os.linux.getcontext` also cannot be
used with bionic libc, so it seems prudent to just disable this extern for now.
This may not be the perfect long-term fix, but I have a golden rebuttal to that:
before I was unable to compile Zig applications for Android, and now I can.

Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
Windows defines `recv` and `recvfrom` to return a value of type `int`,
rather than a pointer-sized signed integer, and so should use `c_int`
rather than `isize` for their return types.
Also add `std.fs.has_executable_bit` for doing conditional compilation.
This adds the linux syscalls for chmod and fchmodat, as well as the
extern libc function declarations.
Only `fchmodat` is added to `std.os`, and it is not yet added to std.fs.
The system linker shows warning when `msync` is linked instead of `__msync13`:
"warning: reference to compatibility msync(); include <sys/mman.h> for correct reference"

This reverts commit aa3964477f.
This declaration is already provided by operating-system-specific files.
This is not the correct solution to the problem.
See #14013Reopens#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.
