Jakob Ivarsson adfc1601c1 Rewrite NetEq stable delay mode. 
The goal is to reduce the amount of time stretching done in response
to network jitter. Specifically, we should be able to “ride” over delay
spikes if the current delay is sufficient, without decelerating
playout. We should also avoid accelerating immediately after a buffer
underrun, until we are reasonably sure that the jitter has passed.
This is achieved by increasing the deadband where we choose to do
normal playout, based on the maximum delay in the short term packet
arrival history.

The buffer level filter is still used to report the average delay for
A/V sync purposes.

The new behavior is behind a flag and will be experimented with before
it is made default.
