Summary:                    [patch] Unload/load support for chan_skinny
Description: 
Reload is not working, but unload and load do work.
My reload code is ugly-simple, it calls the unload 
function, then the load function.  I would have thought
if I could manually unload and load that would be enough.


My threading knowledge is more than a bit weak, but the
existing code was 90% there already.  We needed to store
the address of the skinny_session thread launch from within
accept_thread so we could later cancel it.

Interestingly the skinnysession structure had a member to
store the thread address, but it did not appear to be used.

I also move the teardown of the accept thread to a point before
tearing down the sessions (and their threads) to prevent a phone
from trying to re-register and recreating a session thread after
we had processed it.

---------------------------------------------------------------------- 
After proper clean up of previously allocated devices and lines, I found
that
the soft reset no longer worked.

The patch now 'migrates' state information about existing subchannels and
line hookstate, which is required if we expect stimulus or softkey events
to be handled.

The relationship between lines, device, sessions and subchannels is
amazingly
incestuous.  I think I have covered all of the relationships, and my
single
skinny phone development lab survives back to back reloads, even with
active
calls.

Close scrutiny and testing suggested...
