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.

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.

We should assert when either the function or the flag pointer
is null or we'll end up with a null reference a few lines later.
Currently unused by mesa thus it has gone unnoticed.

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().

GetCurrentThread() returns a pseudo-handle (a constant which only makes
sense when used within the calling thread) and not a real handle.
DuplicateHandle() will return a real handle, but it will create a new
handle every time we call. Calling DuplicateHandle() here means we will
leak handles, which can cause serious problems.
In short, the Windows implementation of thrd_t needs a thorough make
over, and it won't be pretty. It looks like C11 committee
over-simplified things: it would be much better to have seperate objects
for threads and thread IDs like C++11 does.
For now, just comment out the thrd_current() implementation, so we get
build errors if anybody tries to use it.
Thanks to Brian Paul for spotting and diagnosing this problem.

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
