Merge the changes from team/russell/iax2_poke_fix and iax2-poke-fix-trunk

There was a race condition related to the handling of POKEing peers.  Essentially, 
a reference to a peer is held by the scheduler when there are pending callbacks, 
but the reference count didn't reflect it.  So, it was possible for a peer to hit
a reference count of zero and have its destructor begin to be called at the same
time that the scheduler thread ran a POKE related callback.  If that happened,
a crash would likely occur.

(closes issue #11082, closes issue #11094)
