* add new --system command line parameter to the daemon for running PulseAudio as system-wide instance

Browse source 
* add PA_ prefixes to all global #defines
* modify auth-by-creds: define a new group "pulse-access" which is used for authentication
* add proper privilige dropping when running in --system mode
* create runtime directory once on startup and not by each module seperately
