app_queue: Add dialplan function to get the channel name at the specified position in a queue.

The QUEUE_GET_CHANNEL function returns the caller's channel name at the
specified position in a queue.

QUEUE_GET_CHANNEL(<queuename>[,<position>])

The queue position parameter defaults to 1 if not specified.

Noop(${QUEUE_GET_CHANNEL(queuename, 2)})
"SIP/peer-00000002", if queue exist and have at least 2 callers

Noop(${QUEUE_GET_CHANNEL(queuename, 1)})
Noop(${QUEUE_GET_CHANNEL(queuename)})
"SIP/peer-00000000", if queue exist and have at least 1 caller
