Ben Ford	5bacde37a2	res_rtp_asterisk: Add support for sending NACK requests. ... Support has been added for receiving a NACK request and handling it. Now, Asterisk can detect when a NACK request should be sent and knows how to construct one based on the packets we've received from the remote end. A buffer has been added that will store out of order packets until we receive the packet we are expecting. Then, these packets are handled like normal and frames are queued to the core like normal. Asterisk knows which packets to request in the NACK request using a vector which stores the sequence numbers of the packets we are currently missing. If a missing packet is received, cycle through the buffer until we reach another packet we have not received yet. If the buffer reaches a certain size, send a NACK request. If the buffer reaches its max size, queue all frames to the core and wipe the buffer and vector. According to RFC3711, the NACK request must be sent out in a compound packet. All compound packets must start with a sender or receiver report, so some work was done to refactor the current sender / receiver code to allow it to be used without having to also include sdes information and automatically send the report. Also added additional functionality to ast_data_buffer, along with some testing.

Ben Ford	879743ab8f	test_data_buffer.c: Add unit tests for data buffer API. ... Added unit tests for the data buffer API. These tests include creating a data buffer, putting payloads into the buffer, resizing the buffer, and the nominal case for data buffer usage, which consists of adding the max number of payloads to the buffer, checking to see if the correct payloads are present, then adding more payloads and checking again to see if the previous payloads were replaced or not.
