Convert device state callbacks to ao2 objects to fix a deadlock in chan_sip.<br/>
<br/>
Lock scenario presented here:<br/>
Thread 1<br/>
holds ast_rdlock_contexts &conlock<br/>
holds handle_statechange hints<br/>
holds handle_statechange hint<br/>
waiting for cb_extensionstate<br/>
Locked Here: chan_sip.c line 7428 (find_call)<br/>
Thread 2<br/>
holds handle_request_do &netlock<br/>
holds find_call sip_pvt_ptr<br/>
waiting for ast_rdlock_contexts &conlock<br/>
Locked Here: pbx.c line 9911 (ast_rdlock_contexts)<br/>
<br/>
Chan_sip has an established locking order of locking the sip_pvt and then<br/>
getting the context lock. So the as stated by the summary, the operations in<br/>
thread 2 have been modified to no longer require the context lock.<br/>
<br/>
