a5b65058d5 Regularize the vop_stdlock'ing protocol across all the filesystems
that use it. Specifically, vop_stdlock uses the lock pointed to by
vp->v_vnlock. By default, getnewvnode sets up vp->v_vnlock to
reference vp->v_lock. Filesystems that wish to use the default
do not need to allocate a lock at the front of their node structure
(as some still did) or do a lockinit. They can simply start using
vn_lock/VOP_UNLOCK. Filesystems that wish to manage their own locks,
but still use the vop_stdlock functions (such as nullfs) can simply
replace vp->v_vnlock with a pointer to the lock that they wish to
have used for the vnode. Such filesystems are responsible for
setting the vp->v_vnlock back to the default in their vop_reclaim
routine (e.g., vp->v_vnlock = &vp->v_lock).

In theory, this set of changes cleans up the existing filesystem
lock interface and should have no function change to the existing
locking scheme.

a18b1f1d4d Convert lockmgr locks from using simple locks to using mutexes.
Add lockdestroy() and appropriate invocations, which corresponds to
lockinit() and must be called to clean up after a lockmgr lock is no
longer needed.

e39756439c Back out the previous change to the queue(3) interface.
It was not discussed and should probably not happen.

740a1973a6 Change the way that the queue(3) structures are declared; don't assume that
the type argument to *_HEAD and *_ENTRY is a struct.

b17f083b0f Merged NetBSD version, as they have done improvements:
1. ntfs_read*attr*() functions now accept
	uio structure to eliminate one data copying.
	2. found and removed deadlock caused
	by 6 concurent ls -lR.
	3. started implementation of nromal
	Unicode<->unix recodeing.

461b249325 Removed annoying messaged during boot,added some check
before mounting (should help to do not mount extended partitions:-).
Fixed problem with hanging while unmounting busy fs.

And (the most important) added some locks to prevent
simulaneous access to kernel structures!

5ada11aa72 Added limited write ability. Now we can use some kind
of files for swap holders. See mount_ntfs..8 for details.
