Do not assume thrd_t to be a pointer or integer, as the C11 standard tells us:
thrd_t: implementation-defined complete object type identifying a thread
At https://en.cppreference.com/w/c/thread
So we always return the thread creation return code instead of thrd_t value, and judge the return
code properly.

It is not portable to use initial-exec TLS in dlopened libraries. glibc
and FreeBSD allocate extra memory for extra initial-exec variables
specifically for libGL, but other libcs including musl do not.
Keep initial-exec disabled on FreeBSD since it is apparently broken for
some reason:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/966#note_39451281dbdb15d5
Enable TLS on OpenBSD and Haiku based on the u_thread.h comment that
emutls is better than pthread_getspecific, which seems plausible given
that emutls has strictly more information to work with.
Fixes#966.

Thread sanitizer complains if it detects that the pthread_barrier
is destroyed when a thread might still blocked on the barrier.
Fix this by destroying the barrier only if pthread_barrier_wait
returns PTHREAD_BARRIER_SERIAL_THREAD which is the value for success.
In practice this shouldn't fix anything serious given that this code
is only called when the disk cache is destroyed.

Android 29 introduced general-dynamic TLS variable support ("quick
function call to look up the location of the dynamically allocated
storage"), while Mesa on normal Linux has used initial-exec ("use some of
the startup-time fixed slots, hope for the best!"). Both would be better
options than falling all the way back to pthread_getspecific(), which is
the alternative we have pre-29.

Rather than trying to encode all of the rules in a header, lets just put
them in the build system where they belong. This fixes the build on
FreeBSD, which does have pthraed_setaffinity_np, but it's in a
pthread_np.h, not behind _GNU_SOURCE. FreeBSD also implements cpu_set
slightly differently, so additional changes would be required to get it
working right there anyway.

The #if guard is probably not 100% equivalent to the previous PIPE_OS
check, but if anything it should be an over-approximation (are there
pthread implementations without barriers?), so people will get either
a good implementation or compile errors that are easy to fix.
