- Check process name when dealing with PID files

Browse source 
- Add new PA_STREAM_FIX_CHANNELS, FIX_RATE, FIX_FORMAT, DONT_MOVE, VARIABLE_RATES to pa_sream_flags_t adn implement it
- Expose those flags in pacat
- Add notifications about device suspend/resume to the protocol and expose them in libpulse
- Allow changing of buffer_attr during playback
- allow disabling for remixing globally
- hookup polkit support
