Primarily, this patch does the following:
(1) Removes ast_rtp_codecs_packetization_set. This call was effectively a NoOp with res_rtp_asterisk/res_rtp_multicast. The various channel drivers now call ast_rtp_codecs_set_framing where appropriate.
(2) A major overhaul of ast_rtp_codec was done. This includes:
    (a) Storing the framing on the structure. This allows for the smoother in res_rtp_asterisk to easily get the framing specified without having to do major gyrations.
    (b) Payload types (which are ao2 ref counted objects) are no longer stored in an ao2_container. This container had two patterns of usage: lookups by an integer key value and iteration. Vectors work well for this type of access and - for relatively small numbers of items (which is generally the case for payload types), are much faster on both counts.
(3) The 'use_ptime' setting in res_pjsip_sdp_rtp now works. Packetization is also handled a little bit better, as both the RTP engine and format_cap API already do the job of managing the framing.

A variety of ref leaks were cleaned up as well along the way.</pre>

 * Basic Offer/Answer of different sets of codecs (using a variety of patterns, including allow=all (ew))
 * Packetization, including use_ptime=yes|no.
 * AVPF
 * Preferred codec only (by only specifying a single supported codec), subsets of offers, etc.

These tests will eventually get put up on another review, but they gave some confidence that the mucking around in the rtp_engine that is done on this patch works.</pre>
