Summary:                    crash while send call via sip to another asterisk
server into meetme
Description: 
We have a centralized meetme server that other asterisk servers send calls
to.  We have had a several instances of these "client" asterisk servers
crashing when sending calls to meetme on the centralized server (via
Dial(SIP/xxx)).  Unfortunately I have not been able to reproduce this
issue.  Both servers running 1.4.9.  Example bt attached.

Merge the last bit of changes from asterisk/team/russell/readq-1.4

The issue here is that the channel frame readq handling got broken when
the
code was converted to use the linked list macros.  It caused corruption of
the
list head and tail pointers.  So, I fixed up the usage of the linked list
macros and in passing, simplified the code.  I also documented what the
code
is doing, as it was a bit difficult to figure out at first.

This bug showed itself with crashes showing messed up head/tail pointers
for
the readq.  However, there are a couple of crashes that aren't quite as
obvious,
but I think may be related.  So, if your bug gets closed by this commit,
but
you still have a problem, please reopen or create a new bug report.
