[Asterisk-code-review] res rtp asterisk: Add support for receiving and handling NAC... (asterisk[15])

[Benjamin Keith Ford]

Hello Jenkins2, Joshua Colp, 

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

    https://gerrit.asterisk.org/8773

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

Change subject: res_rtp_asterisk: Add support for receiving and handling NACK requests.
......................................................................

res_rtp_asterisk: Add support for receiving and handling NACK requests.

Adds the ability to receive and handle incoming NACK requests if
retransmissions are enabled. If retransmissions are enabled, a data
buffer is allocated that stores packets being sent. If a NACK request
is received, the packet requested for retransmission is sent if it is
still in the buffer. In the same request, if any of the following 16
packets are marked as not received, those will be sent as well if
available, as outlined in RFC4585.

Also changes RTCP RR and SR to use media source SSRC instead of packet
source SSRC when determining which instance to use for RTCP reports.

For more information, refer to the wiki page:
