8f63187ec1 Add LK_NOWITNESS to the vn_lock() calls done on newly created nfs
vnodes, since these nodes are not linked into the mount queue and,
as such, the vn_lock() cannot cause a deadlock so LORs are harmless.

d00a615a98 Add a check to v_type == VREG for the recently modified code that
does NFSv4 Closes in the experimental client's VOP_INACTIVE().
I also replaced a bunch of ap->a_vp with a local copy of vp,
because I thought that made it more readable.

fdd88deeba Fix handling of NFSv4 Close operations in ncl_inactive(). Only
do them for NFSv4 and flush writes to the server before doing
the Close(s), as required. Also, use the a_td argument instead of
curthread.

47a598563d Change the experimental NFSv4 client so that it does not do
the NFSv4 Close operations until ncl_inactive(). This is
necessary so that the Open StateIDs are available for doing
I/O on mmap'd files after VOP_CLOSE(). I also changed some
indentation for the nfscl_getclose() function.

9ec7b004d0 Add the experimental nfs subtree to the kernel, that includes
support for NFSv4 as well as NFSv2 and 3.
	It lives in 3 subdirs under sys/fs:
	nfs - functions that are common to the client and server
	nfsclient - a mutation of sys/nfsclient that call generic functions
	to do RPCs and handle state. As such, it retains the
	buffer cache handling characteristics and vnode semantics that
	are found in sys/nfsclient, for the most part.
	nfsserver - the server. It includes a DRC designed specifically for
	NFSv4, that is used instead of the generic DRC in sys/rpc.
	The build glue will be checked in later, so at this point, it
	consists of 3 new subdirs that should not affect kernel building.
