once: Fix race causing pa_once to sometimes run twice
...
There was a race in the existing code that could cause the pa_once code
to be run twice, see:
http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-April/013354.html
Therefore the existing implementation was rewritten to instead look like
the reference implementation here:

rework pa_once once again, because the once function needs to have terminated before pa_once returns, regardless whether the local call executes it or another thread does.
...
With the previous code it might happen that an long-running initializing in a once function is not terminated yet when another thread thinks it already is.
