Summary:                    [patch] MFC/R2 support for chan_zap
Description: 
Here we go. This is my first try to give R2 support to chan_zap. I'm sure I
am missing locks and/or features here and there but I have tested it
internally with success with a considerable amount of concurrent channels
(64). That's the best I can do with the hardware I currently have (more
coming!).
