New Revision: 399658
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=399658
Log:
Add the ability to mark a channel as staging a snapshot.
This code will prevent internal operations from creating and publishing
a channel snapshot. It is up to the stager to finish staging, which then
creates a snapshot and publishes it.
