Summary:                    Channel hangs up when redirected through CLI or AMI
Description: 
SVN revision 293045:

When a channel is redirected using either CLI or AMI, the channel hangs
up. This has been tested for GTalk and SIP channels. Redirecting any of
these two channels to console channel, musiconhold, or SIP channel triggers
the above bug. The bug has not been tested for other channel combinations.

    The channel redirect function (CLI or AMI) hangs up the call instead
of redirecting the call.
    
    To recreate the problem:
    1) Party A calls Party B
    2) Invoke CLI "channel redirect" command to redirect channel call leg
    associated with A.
    3) All associated channels are hung up.
    
    Note that if the CLI command were done on the channel call leg
associated
    with B it works.
    
    This regression was a result of the fix for issue
https://issues.asterisk.org/view.php?id=16946
    (https://reviewboard.asterisk.org/r/740/).
    
    The regression affects all features that use an async goto to execute
the
    dialplan because of an external event: Channel redirect, AMI redirect,
SIP
    REFER, and FAX detection.
    
    The struct ast_channel._softhangup code is a mess.  The variable is
used
    for several purposes that do not necessarily result in the call being
hung
    up.  I have added doxygen comments to describe how the various
_softhangup
    bits are used.  I have corrected all the places where the variable was
    tested in a non-bit oriented manner.
    
    The primary fix is the new AST_CONTROL_END_OF_Q frame.  It acts as a
weak
    hangup request so the soft hangup requests that do not normally result
in
    a hangup do not hangup.
