354104f9a9 thread/{Thread,Id}: use defaul-initialized pthread_t as "undefined" value 
Use the "==" operator instead of pthread_equal().

This allows us to eliminate two boolean flags which are there to avoid
race conditions, and made the thing so fragile that I got tons of
(correct) thread sanitizer warnings.

dfaf08743c *: check defined(_WIN32) instead of defined(WIN32) 
Only _WIN32 is defined by the compiler, and WIN32 is not standardized
and may be missing.

8bbfb5cda1 thread/PosixCond: fix timed_wait 
pthread_cond_timedwait() in PosixCond.hxx:timed_wait(PosixMutex...) returns
EINVAL, if ts.tv_nsec >= 1E9. In this case, it returns to early.

Find attached a patch which fixes this. I chose a compare-subtraction method
to keep ts.tv_nsec below 1E9.

Another option would be
ts.tv_sec += ts.tv_nsec / 1000000000;
ts.tv_nsec %= 1000000000;

But I guess this takes more time on some ARM processors, which don't support
hardware division.

3392cbbd91 Emit a warning if the OutputThread fails to get realtime scheduling 
This only applies to linux systems.  Here, sched_setscheduler() is
called to get realtime scheduling.  With this patch, the return value
of this function is now checked and a warning / error message is
generated if it fails.

4bd2c75056 thread/Name: disable pthread_setname_np() on NetBSD 
NetBSD's pthread_setname_np() prototype is incompatible with the rest

disable the feature on NetBSD.

d8fc2db910 thread/Id: drop "::" prefix before pthread function names

e304d0f8ee thread/Posix{Cond,Mutex}: don't ues PTHREAD_*_INITIALIZER on NetBSD 
On NetBSD, PTHREAD_MUTEX_INITIALIZER and PTHREAD_COND_INITIALIZER are
not compatible with C++11 "constexpr" (see Mantis ticket 0004110).  As
a workaround, don't ues "constexpr", and use the functions
pthread_mutex_init(), pthread_mutex_destroy(), pthread_cond_init() and
pthread_cond_destroy() instead.  This adds some runtime overhead, but
is portable to POSIX implementations that have awkward initializer
macros.
