[svn-commits] rmudgett: branch 12 r424103 - /branches/12/res/

[SVN commits to the Digium repositories]

Author: rmudgett
Date: Mon Sep 29 16:16:22 2014
New Revision: 424103

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=424103
Log:
Simplify UUID generation in several places.

Replace code using ast_uuid_generate() with simpler and faster code using
ast_uuid_generate_str().  The new code avoids a malloc(), free(), and
copy.
