Summary:                    [patch] Hangup extension executed twice in 1.6.2 RC2
Description: 
When a user hangs up a call, in certain circumstances, the hangup extension
can end up being executed twice.

If I comment out this section of my dialplan, the hangup extension is only
executed once:

exten => _X.,n,Goto(s-${DIALSTATUS})

exten => s-CONGESTION,1,Congestion(5)
exten => s-BUSY,1,Busy(5)
exten => s-.,1,Congestion(5)

Otherwise, the hangup extension is executed twice.  The odd thing is that
the console output does not display that the code above is being executed.

  Fix erroneous hangup extension execution
  
  ast_spawn_extension behaves differently from 1.4 in that hangups and
extensions
  that do not exist do not return an error, whereas in 1.6 it does. This
is now 
  taken into account so that the AST_FLAG_BRIDGE_HANGUP_RUN flag gets set
  properly.
