Subject: [PATCH] VCHIQ: Make service closure fully synchronous (lib)

This is one half of a two-part patch, the other half of which is to
the vchiq_arm kernel driver. With these patches, calls to
vchiq_close_service and vchiq_remove_service won't return until any
associated callbacks have been delivered to the callback thread.
mmal: Add call to check for connected port
mmal: Initial stereoscopic camera work
