New Revision: 167018
URL: http://svn.digium.com/view/asterisk?view=rev&rev=167018
Log:
Get rid of the taskprocessor used for waiting for FULLY_BOOTED and just handle the tech specific calendar loading in ast_calendar_register (as per russell on reviewboard). We are still only reading the config file once and keeping the config around in a global variable that the calendar techs can see.
