[SVN commits to the Asterisk project]

New Revision: 367837

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=367837
Log:
Add the ability to match an option value via callback

For example, SIP entries users.conf can contain the hassip and
registersip options which need to be tested against ast_true() to be
able to determine whether the context should create a sip_peer or
sip_registry.
