Author: mmichelson

New Revision: 390510

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=390510
Log:
Change the remove_on_pull flag on ast_bridge_hook to be a set of flags.

This change is used to make bridge hook removal more generic. This way,
depending on the circumstance, the appropriate bridge hooks may be
removed.
