NLM locks don't conflict with NFSv4 share reservations, so we're not
going to learn anything new by watiting for them.
They do conflict with NFSv4 locks and with delegations.

Currently, all of the grace period handling is part of lockd. Eventually
though we'd like to be able to build v4-only servers, at which point
we'll need to put all of this elsewhere.
Move the code itself into fs/nfs_common and have it build a grace.ko
module. Then, rejigger the Kconfig options so that both nfsd and lockd
enable it automatically.
