vcl: add api to expose worker message queues epfd
This only works if vcl is configured to do eventd based message queue notifications, instead of condvars. For that, add "use-mq-eventfd" to vcl startup conf. Change-Id: Id0f0288a40ec7d3daef7370f8b88420425867ab6 Signed-off-by: Florin Coras <fcoras@cisco.com>
