[SVN commits to the Asterisk project]

New Revision: 182553

URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=182553
Log:
Tweak the handling of the frame list inside of ast_answer().

This does not change any behavior, but moves the frames from the local frame
list back to the channel read queue using an O(n) algorithm instead of O(n^2).
