[Asterisk-code-review] rtp: Only accept the first payload for a format in SDP. (asterisk[14])

[Joshua Colp]

Hello Richard Mudgett, Anonymous Coward #1000019,

I'd like you to reexamine a change.  Please visit

    https://gerrit.asterisk.org/3894

to look at the new patch set (#3).

Change subject: rtp: Only accept the first payload for a format in SDP.
......................................................................

rtp: Only accept the first payload for a format in SDP.

When receiving an SDP offer with multiple payloads for
the same format we would generate an answer with the first
payload, but during the payload crossover operation
(to set the payloads for receiving) we would remove all
payloads but the last. This would result in incoming
traffic being matched against the wrong format and outgoing
traffic being sent using the wrong payload.

This change makes it so that one a format has a payload
number put into the mapping all subsequent ones are ignored.
This ensures there is only ever one payload in the mapping
and that it is the payload placed into the answer SDP.
