mod_sofia will now examine a variable in the channel to
see what the channel's originator was using for a codec and 
try to put that to the top of the list in the sdp.

if this new sofia profile param is set:
<param name="disable-transcoding" value="true"/>

All outbound calls will use *only* the codec that thier originator 
is using to ensure no transcoding.
(of course that could lead to a failed call where there is no way to do this, so use sparingly)
