This changes appletalk to use lock_sock instead of
lock_kernel for serialization. I tried to make sure
that we don't hold the socket lock during sleeping
functions, but I did not try to prove whether the
locks are necessary in the first place.

Compile-tested only.

If you're moving appletalk to staging because "nobody is motivated
enough to remove the BKL" and then you actually do the work to remove
the BKL, I really don't see any point in doing the whole staging
thing.

We always keep an eye on every protocol that sits under the top-level
net/.  Every socket API change propagates, as does every other
networking API change that matters for those protocols.

You can move appletalk down to staging if that stops happening, which
it won't.
