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.

---------------------------------------------------------------------- 
The lines with SKINHY_LAMP_BLINK control the icon next to the line
buttons (and the back-light buttons on the newer phones).
I did not trace out those calls or do a packet capture, I just brought
forward the code that was already there.

Let me know if it needs further rework.
