b8fcae6d75 Reserving flags for coming code (currently in the "videocaps" branch) 
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.

Code by John Martin, Aupix (disclaimer on file)

option for setting our own packetization as apposed to just doing 
what is asked.

4de3c0e447 Add the ability to specify that a frame should not be considered for caching 
for uses in cases where you *know* that it will do no good.  This patch was
inspired by file for use in some work of his on mixmonitor/chanspy.

f7e7161607 Merge team/russell/frame_caching 
There are some situations in Asterisk where ast_frame and/or iax_frame
structures are rapidly allocatted and freed (at least 50 times per second
for one call).

This code significantly improves the performance of ast_frame_header_new(), 
ast_frdup(), ast_frfree(), iax_frame_new(), and iax_frame_free() by keeping
a thread-local cache of these structures and using frames from the cache 
whenever possible instead of calling malloc/free every time.

This commit also converts the ast_frame and iax_frame structures to use the
linked list macros.

bb7dd96cfe Add support for using a jitterbuffer for RTP on bridged calls. This includes 
a new implementation of a fixed size jitterbuffer, as well as support for the
existing adaptive jitterbuffer implementation. (issue #3854, Slav Klenov)

Thank you very much to Slav Klenov of Securax and all of the people involved
in the testing of this feature for all of your hard work!
