Commit Message

Optimize ice.Agent.getBestPair()

This function should be trivial but profiles show it taking 3-5% of my
application's CPU time. The problem is the constant creation of a
channel for message passing. This function is called by srtp.WriteRTP
for each packet, so it adds up.

My fix was to create a `runInner` function that utilizies a mutex. I
wanted to convert all `run` functions to `runInner` but the code
occasionally deadlocks in unit tests. The package is definitely a
candidate for a rewrite.
