Summary:                    Queue is treated as empty if it isn't, but no agents
meet the QUEUE_MIN_PENALTY and QUEUE_MAX_PENALTY criteria
Description: 

In a situation where a call is placed into a queue as follows:

exten => s,n,Set(QUEUE_MAX_PENALTY=1)
exten => s,n,Set(QUEUE_MIN_PENALTY=1)
exten =>
s,n,Queue(${ORGCODE}_${ORGQUEUE},ih,,${ORGCODE}/announce-incoming)
)
The queue is deemed to be empty if there are no agents with a penalty of 1
as a member of the queue.

We use queuerules.conf to raise the QUEUE_MAX_PENALTY value to overflow
calls to other departments and in our case (and I can imagine, other
people's too), it is perfectly legitimate to have members with a penalty of
2 logged in and no members with penalty 1.

As a result of this, the function QUEUE_MEMBER() returns incorrect data
(i.e. QUEUE_MEMBER(free) may return the "number of logged-in members for
the specified queue available to take a call" as 10, but in reality and
because of the penalty issue, it is zero.

I have been able to work around this by checking QUEUE_MEMBER(count) after
I receive a JOINEMPTY bounce out, incrementing QUEUE_MAX_PRIORITY and
trying again, but this is far from ideal!

Major problem. It's started core dumping.

It was working absolutely fine until the middle of the day yesterday when
it started crashing Asterisk:

This is a production box and I hadn't removed optimisation when I compiled
it, so although I have the dumps, I imagine they'd be useless.

I reverted to the original app_queue.c and it's been OK overnight and this
morning so far.
