[Asterisk-code-review] RTP/ICE: Send on first valid pair. (asterisk[16])

[Benjamin Keith Ford]

Hello Joshua Colp, George Joseph, Kevin Harwell, Friendly Automation, 

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

    https://gerrit.asterisk.org/c/asterisk/+/13673

to look at the new patch set (#8).

Change subject: RTP/ICE: Send on first valid pair.
......................................................................

RTP/ICE: Send on first valid pair.

When handling ICE negotiations, it's possible that there can be a delay
between STUN binding requests which in turn will cause a delay in ICE
completion, preventing media from flowing. It should be possible to send
media when there is at least one valid pair, preventing this scenario
from occurring.

A change was added to PJPROJECT that adds an optional callback
(on_valid_pair) that will be called when the first valid pair is found
during ICE negotiation. Asterisk uses this to start the DTLS handshake,
allowing media to flow. It will only be called once, either on the first
valid pair, or when ICE negotiation is complete.

ASTERISK-28716
