Some programs use C11 threads instead of POSIX threads, so this change
implements a light wrapper around POSIX threads that conforms to the
C11 spec.
This code was primarily taken from FreeBSD, with minor modifications:
- The header file was trimmed to only include functions in the C11
spec, and changed to match the format of other Haiku header files
- The thrd_yield function was implemented with its POSIX equivalent
sched_yield instead of the non-standard pthread_yield
- The thrd_create function was changed to return thrd_busy on an
EAGAIN error code instead of unconditionally returning thrd_error
The respective files can be found in the FreeBSD source tree at:
- lib/libstdthreads/threads.h
- lib/libstdthreads/thrd.c
TODO:
- untested (is a unit test in order?)
