Summary:                    [patch] Jitterbuffer stops accepting new frames
until it is empty after maxjitterbuffer is exceeded.
Description: 
Once the jitterbuffer exceeds maxjitterbuffer it stops accepting new frames
until the buffer is emptied.  This can cause large audio dropouts.

Improve behavior of jitterbuffer when maxjitterbuffer is set.

This change improves the way the jitterbuffer handles maxjitterbuffer and
dramatically reduces the number of frames dropped when maxjitterbuffer is
exceeded.  In the previous jitterbuffer, when maxjitterbuffer was
exceeded, all
new frames were dropped until the jitterbuffer is empty.  This change
modifies
the code to only drop frames until maxjitterbuffer is no longer exceeded.

Also, previously when maxjitterbuffer was exceeded, dropped frames were
not
tracked causing stats for dropped frames to be incorrect, this change also
addresses that problem.
