OK, I went for the former; if you'd rather get this out of git, you can

	git clone http://www.linux-nfs.org/~bfields/linux.git
	git checkout server-cluster-lease-api

The changes from the last version seem pretty trivial, but I've
compile-tested this only for now.

I'm ignoring the problem of breaking leases on unlink and rename.  I
think we should go ahead and do this part now--it's adequate for the
current lease semantics, and even more so for our current application
(just turning off leases selectively on some filesystems)--but I'd
really like to solve that problem eventually.

That's probably not going to happen until we get a cluster filesystem
with real lease support into the kernel....

Changes:
	- do away with the break_lease method.
	- rename __setlease to setlease, setlease to vfs_setlease, and
	  make sure it's setlease (the one that doesn't call into the
	  filesystem) that's exported.
	- rename ->set_lease to ->setlease.  (I don't really care which
	  we go with, it just seemed confusing when everything else was
	  already named without the underscore.)
	- Add a trivial patch that disables leases on nfs (as suggested
	  by a patch elsewhere from Peter Staubach)
