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.
