------------------------------------------------------------------

After a little more external testing, chan_gulp/res_sip needs to reject SDP where any two streams have the same non-zero port.  Otherwise, we might accidentally support optional-SRTP.

Looking internally, things need to be modified.  The media streams currently reside in a static array on the ast_sip_session (severely restricts new stream types and restricts to one stream of a given type which is currently, but not always desirable) and all registered sdp media type handlers are available to all sessions (prevents disallowing specific stream types on individual endpoints).

> Currently, {{chan_gulp}} only supports audio. While that's nice, we're going to eventually want to have video and fax. And text (why not).
> Note that while it has larger implications than just the channel driver, the structure of the objects should allow for multiple media streams of a particular type. The actual creation of the media streams can bail if someone requests multiple types, but if the core ever supports such a concept the channel driver should be ready to accept it.
