SVN commits to the Digium repositories

Tue Mar 23 16:07:57 CDT 2010
Author: qwell
Date: Tue Mar 23 16:07:54 2010
New Revision: 254046
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=254046
Log:
Allow out-of-tree modules to load, regardless of DEBUG_THREADS/DEBUG_CHANNEL_LOCKS differences.
This can be guaranteed by forcing the ABI to no longer change when these compiler flags are set.
An unfortunate side-effect to this is that there is an ABI change here. However, there is some
mitigation. Existing modules *will* fail to load since they would require functions that no
longer exist.
