Add a VRF_MASTER flag for interfaces and helper functions for determining
if a device is a VRF_MASTER.
Also, add link attribute for passing VRF_TABLE id.
Both are used in the following patch that adds a VRF device driver.

Also, why calling this '_MASTER', is there a notion of SLAVE?

Usally, the index of an interface is named 'ifindex', it eases code reading
to keep the same name. Something like:
