SBC minimized transcoding implementation

[GoogleCodeExporter]

In this mode sbc should set to top of list codecs received from first UA, but 
will add supported under transcoding codecs after that.Depending on answer 
received from second UA endpoint will work either as pass through ( if both 
sides support any of codecs ) or transcoded otherwise.
