Richard Mudgett aec1979e7f Remove potential deadlock in call pickup race. ...

Deadlock is possible in ast_do_pickup() when holding the target channel
lock and trying to get the chan channel lock.  Also, holding the target
lock when calling ast_channel_masquerade() is not a good idea because that
routine does deadlock avoidance.

* Removed the need to hold the target lock after marking the target with a
datastore and getting the connected line data off of the target channel.

* Moved can_pickup() to ast_can_pickup() in features.c.  Now all the call
pickup methods use the same basic call pickup availability check.
