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