Summary:                    [patch] zap restart fails to generate channels
Description: 
The command "zap restart" has been added before 1.4 . However at some point
it has been changed to run setup_zap(2) instead of setup_zap(0) . This
makes it useless, as it can only destroy channels and not create new ones.

The attached patch fixes this, as well as other implementation issues with
zap_restart:

* Just release all the interfaces at once. The same code as in the module
unload.

* Thus we also lock the iflist when destroying channel.

* If we were listening on some file descriptors and now we don't, pfds was
still pointing to a value even though its value has been released.


With this patch a restart of analog channels work. A restart of digital
spans still fails, as there is no where in the code that D channels are
being released.
