>  Resolve deadlock involving REFER.
>  
>  Two fixes:
>  1) One must always have the private unlocked before calling
>  pbx_builtin_setvar_helper to not invalidate locking order since it locks the
>  channel.
>  2) Unlock the channel before calling pbx_find_extension, which starts and stops
>  autoservice during the lookup. The problem scenario as illustrated by the
>  reporter:
>  
>  Thread: do_monitor
>  -----------------------
>  handle_request_do
>   handle_incoming
>    handle_request_refer
>     ast_parking_ext_valid
>      pbx_find_extension
>       ast_autoservice_stop
>        while (chan_list_state == as_chan_list_state) { usleep(1000); }
>  
>  Thread: autoservice_run
>  -----------------------
>  autoservice_run
>   chan = ast_waitfor_n
>    ast_waitfor_nandfds
>     ast_waitfor_nandfds_classic / simple / complex (depending on your system)
>      ast_channel_lock(c[x]);
>  
>  handle_request_do and schedule_process_request_queue locks the owner
>  if it exists. The autoservice thread is waiting for the channel lock, which
>  wasn't ever released since the do_monitor thread was waiting for autoservice
>  operations to complete. Solved by unlocking the channel but keeping a reference
>  to guarantee safety.
