Summary:                    chan_isavail segfaulting asterisk after sip_hangup
(introduced after http://bugs.digium.com/view.php?id=8556 changes)
Description: 
While testing a pristine copy of Asterisk before going after
http://bugs.digium.com/view.php?id=12248 I've
got a segfault when ast_hangup(tempchan) is called from app_chanisavail,
which then calls sip_hangup and crash. It was introduced after the commits
for http://bugs.digium.com/view.php?id=8556 (revision 108439).

The problem seems to be lying under if (!p->alreadygone &&
!ast_strlen_zero(p->initreq.data->str)) though my friends and I are not
completely sure.
