[Asterisk-code-review] parking: Use channel snapshot instead of channel. (asterisk[13])

[Joshua Colp]

Hello George Joseph, Friendly Automation, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/13173

to look at the new patch set (#3).

Change subject: parking: Use channel snapshot instead of channel.
......................................................................

parking: Use channel snapshot instead of channel.

There exists a scenario where a thread can hold a lock on the
channels container while trying to lock a bridge. At the same
time another thread can hold the lock for said bridge while
attempting to retrieve a channel. This causes a deadlock.

This change fixes this scenario by retrieving a channel snapshot
instead of a channel, as information present in the snapshot
is all that is needed.
