  Better way to get chan and pvt lock for issue ASTERISK-17431.
  
  Redoes -r308945 for issue ASTERISK-17431 deadlock fix for
  sip_set_udptl_peer() and sip_set_rtp_peer().
  
  * Lock the channels in the defined order and avoid the need for a deadlock
  avoidance loop.
  
  * Lock the channel before getting the pointer to the private structure to
  be sure that the pointer will not change due to a masquerade or channel
  hangup.
  
  * To preserve sanity, check that chan and p->owner are the same.  (Pointer
  rearangements should not happen without the protection of locks because
  bad things tend to happen otherwise.)
