Code

added parsing of new icy-audio-info header which will be used to

Browse Source 
communicate things like samplerate/quality/number of channels to
icecast2. This info will be then forwarded to the yp servers for
better stream info.

also factored out some logic in source_main into common functions

added a few new routines into util.c (taken from Brendan's
updates to libshout)
