Matt Turner c8dc04d4c0 c11/threads: Assert that mtx is non-NULL and check return values.
Passing NULL to C11 threads functions isn't safe, so there's no need for
our implementation to handle it. Cuts about 1k of .text.

Felix Janda aead7fe2e2 c11/threads: Use PTHREAD_MUTEX_RECURSIVE by default
Previously PTHREAD_MUTEX_RECURSIVE_NP had been used on linux for
compatibility with old glibc. Since mesa defines __GNU_SOURCE__
on linux PTHREAD_MUTEX_RECURSIVE is also available since at least
1998. So we can unconditionally use the portable version
PTHREAD_MUTEX_RECURSIVE.

Brian Paul eaf9affa5e c11/threads: don't include assert.h if the assert macro is already defined
In the gallium code, the assert() macro could come from either the
system's assert.h file (via c11/threads.h) or from gallium's u_debug.h.
It looks like all known assert.h files unconditionally #undef assert
before defining their own version.  So the assert you get depends on
whether threads.h or u_debug.h was included last.

In the gallium code we really want to use the assert() from u_debug.h
(it behaves better on Windows).  In gallium, c11/threads.h is only
included after u_debug.h in the os_thread.h wrapper.  So Adding
an #ifndef assert test in the threads*.h files avoids using the system's
assert().

José Fonseca ecaa81bd96 c11: Import threads.h emulation library.
Implementation is based of https://gist.github.com/2223710 with the
following modifications:
- inline implementatation
- retain XP compatability
- add temporary hack for static mutex initializers (as they are not part
  of the stack but still widely used internally)
- make TIME_UTC a conditional macro (some system headers already define
  it, so this prevents conflict)
- respect HAVE_PTHREAD macro
