New Revision: 58507

URL: http://svn.digium.com/view/asterisk?view=rev&rev=58507
Log:
First cut of IPv6 port of RTP. Make it IP version independent.
Because multiple channels are using RTP and we want to do incremental changes to channels, one channel at a time, it was chosen to duplicate the rtp routines, name the new ones with vi prefix (ast_virtp instead of ast_rtp), and then make the IPv6 changes there. That way, each channel can be updated asynchronously by using the new ast_virtp routines. Better stability during the transition time. However, disadvantage is we need to manually patch the ast_virtp routines with the changes made in ast_rtp ones.
