[Asterisk-code-review] app: Queue hangup if channel is hung up during sub or macro ... (asterisk[11])

[Joshua Colp]

Hello Kevin Harwell, Mark Michelson, Richard Mudgett, Anonymous Coward #1000019,

I'd like you to reexamine a change.  Please visit

    https://gerrit.asterisk.org/1997

to look at the new patch set (#2).

Change subject: app: Queue hangup if channel is hung up during sub or macro execution.
......................................................................

app: Queue hangup if channel is hung up during sub or macro execution.

This issue was exposed when executing a connected line subroutine.
When connected or redirected subroutines or macros are executed it is
expected that the underlying applications and logic invoked are fast
and do not consume frames. In practice this constraint is not enforced
and if not adhered to will cause channels to continue when they shouldn't.
This is because each caller of the connected or redirected logic does not
check whether the channel has been hung up on return. As a result the
the hung up channel continues.

This change makes it so when the API to execute a subroutine or
macro is invoked the channel is checked to determine if it has hung up.
If it has then a hangup is queued again so the caller will see it
and stop.
