As per [MS-TURN] Section 2.2.1, TURN message type 0x0104 "Send request
response" isn't supported and the TURN server MUST NOT send them. Thus,
libnice should not remember Send requests in agent->sent_ids because
without replies coming, the number of allowed pending transaction gets
quickly exhausted, causing our data packets to be dropped until a
request timeout frees some space in the queue.

This behavior resulted in choppy reception of our audio on a Lync client
when connected via Lync Edge (TURN) Server.
