Add a new action type OVS_ACTION_ATTR_SET_MASKED, and support for
parsing, printing, and committing them.
Masked set actions add a mask, immediately following the netlink
attribute data, within the netlink attribute itself. Thus the key
attribute size for a masked set action is exactly double of the
non-masked set action.
