Reserving flags for coming code (currently in the "videocaps" branch)

Browse Source 
implementing T.140 support in RTP.

T.140/RFC 4351 is TDD over IP - text telephony for hearing impaired.
It defines a realtime text chat, much like the old "talk" application
in Unix. 

T.140 is character by character in real time. It's not 
the same as our current MESSAGE format - that is more like IM, but
can be gatewayed to MESSAGE with a text "codec" if needed.

More patches will follow, as soon as we've separated this code from
the video capabilities functions in the videocaps branch.
