Log Message:
Various (including critical) bugfixes in the pulseaudio backend:

Fix assertion triggered in pulsaudio by returning "unknown" instead
of NULL pointer when guessing application name.

Own improvements:
- Use getprogname on NetBSD as it wont return NULL
- Also identify stream as "SDL Application"

3rd party bugfixes:
- Pull buffer size and other fixes from pulsaudio developers.
