pulse-server: improve FIX_ flag handling

Browse source 
When a stream uses the FIX_ flags it should negotiate to the format of
the sink or source it connects to. To do this, look up the sink or
source and look at the format, use this as the allowed format for the
stream when the FIX flags are set.

Make it still possible to override with with properties. Use
audio.position to make it possible to set a channelmap override.
