Summary:                    [patch] segfault checking messages using mwi events
Description: 
I have been chasing a regular crash involves chan_skinny and IMAP enable
voicemail.

I'm following the bugs related to the c-client related crashes, which may
help, but the more I looked at the code that I ported from chan_zap to 
chan_skinny to enable mwi events, the more convinced I became that it was
just
not right.

So I dove into chan_sip to get a handle on how mwi event callbacks should
be
used and developed the attached patch.

Redo the event-based MWI in chan_skinny.

Dan saw regular segfaults with the old implementation and
rewrote it to make it really eventbased.
I altered it to be trunk compatible and wedhorn gave some feedback
and ideas how to make it even better.
