New Revision: 111245

URL: http://svn.digium.com/view/asterisk?view=rev&rev=111245
Log:
Remove excessive smoother optimization that was causing audio glitches (small "pops")
 after (about 200ms later) an "incorrectly" sized frame was received.

While it would be very nice to keep this as optimized as possible, it makes no sense
 for the smoother to be dropping random bits of audio like this.  Isn't that the
 whole point of a smoother?

Closes issue #12093.
