Summary:                    [patch] Change readq locking
Description: 
Revision of chan->readq locking to utilise a list lock rather than the chan
lock. The main advantage of this patch is that channels need not lock
before calling ast_queue_frame or related functions purely to avoid a
deadlock.

Obvious changes to chan_sip and chan_iax have been included. I'm sure
there are others.

aragon, looks like there is no way this is going to be applied to anything
but trunk (see
http://lists.digium.com/pipermail/asterisk-dev/2010-February/042425.html).

The patch may take a bit longer as I'll look at integrating an atomic
update of softhangup so we can remove all chan locking around readq
changes.
