Jeff Peeler 6bb8cc3a9b Fix SIP deadlock involving state changes. ...

Once again a call to pbx_builtin_getvar_helper (and pbx_builtin_setvar_helper)
has caused locking problems. Both of these functions lock the channel when
the channel argument is passed in!

In this case, the suspected problem (the backtrace makes it impossible to tell)
was the private being locked in sip_set_rtp_peer and then:
transmit_reinvite_with_sdp
 try_suggested_sip_codec
   pbx_builtin_getvar_helper
(Traced to verify that the fix was only required in 1.8 and later.)
