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.
