d8e2b3a78c Fix undefined behaviour in pulseaudio --start. 
Don't call pthread_join() to join a thread from a different
process than the thread was created in. Doing so can lead to
undefined behaviour.

On OpenBSD, the symptom was a pulseaudio process with a single
thread waiting forever for other threads to join. Since that
process also held the autospawn lock, starting new pulseaudio
processes with --start kept failing. The problem was analyzed
with help from Philip Guenther.

This patch adds a pa_thread_free_nojoin() function which can
be used to free resources for a thread without a join, as
suggested by Tanu Kaskinen.

2411d9accd thread-posix: Use pthread_(get|set)name_np() if available 
Newer generations of libpthread have functions to set and get the thread
names. If available, use them.

6a2dffd78a unfortunately we cannot detect if a foreign thread is still running. Thus sucks. But what can we do? U. Drepper thinks our use case is invalid.
