[libc][support] move CndVar to support (#89329)

2024-05-21T22:49:42+00:00

We should be able to reuse this between the implementation of C11 cnd_t
condition variables and POSIX pthread_cond_t condition variables.

The current implementation is hyper linux specific, making use of Futex. That
obviously wont work outside of linux, so split the OS specific functions off
into their own source outside of the header.

Modifies the return values of the to-be-shared impl to return 0 on success and
-1 on error.  This pattern was shamelessly stolen from Bionic's
[__bionic_thrd_error](https://android.googlesource.com/platform/bionic/+/refs/heads/main/libc/include/bits/threads_inlines.h#41).

[libc][NFC] Add a platform independent thread support library.

2022-03-04T18:33:46+00:00

The idea is that, other parts of the libc which require thread/lock
support will be able to use this platform independent setup.

With this change, only the linux implementation of a mutex type has been
moved to the new library. Because of this, there is some duplication
between the new library and src/threads/linux. A follow up change will
move all of src/threads/linux to the new library. The duplication should
be eliminated with that move.
