Andrew Zaborowski 6484b7dbb6 Add a new frame watch API
This new API is independent of netdev.c and allows actually
unregistering from receiving notifications of frames, although with some
quirks.  The current API only allowed the callback for a registration to
be forgotten but our process and/or the kernel would still be woken up
when matching frames were received because the kernel had no frame
unregister call.  In the new API you can supply a group-id paramter when
registering frames.  If it is non-zero the frame_watch_group_remove() call
can be used to remove all frame registrations that had a given group-id
by closing the netlink socket on which the notifications would be
received.  This means though that it's a slightly costly operation.

The file is named frame-xchg.c because I'm thinking of also adding
utilities for sending frames and waiting for one of a number of replies
and handling the acked/un-acked information.
