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.

Hangup extension executed twice.

When a user hangs up a call, in certain circumstances, the hangup
extension can end up being executed twice:

1) If a call is bridged and the 'h' extension executes the Hangup
application, then the 'h' extension will be executed twice.

2) If a call is bridged within a macro (Dial or Queue), it has its own 'h'
extension, the main context also has an 'h' extension, and the macro 'h'
extension executes the Hangup application, then both 'h' extensions will
be executed.

* Revert originally commited fix for
https://issues.asterisk.org/view.php?id=16106 and just set
AST_FLAG_BRIDGE_HANGUP_RUN unconditionally in ast_bridge_call().  The
bridge code just executed an 'h' extension so the main PBX loop does not
need to execute one as well.
