bread() always
takes DEV_BSIZE address units so don't bother getting the disklabel and trying to
convert units to d_secsize. Nukes last references to d_secsize in ufs/.

and return EOPNOTSUPP directly from the VOP_* functions.
Filesystems should, at some point fill in every function
in the vop_default struct so we can get rid of the 'if'
statements in VOP_*.

curproc. A bunch of callers were passing in 0 (not even NULL, 0) as this
pointer, which was fine until the called vnode function tried to do
something with it. Typically, this code was then copy/pasted to various
parts of the tree.
Accept the facts of life and switch all of these over to passing curproc
for now until the argument can be removed.
Discovered by stsp trying to create a softraid on top of a vnd, which
crashed with a NULL deref in vndioctl.
softraid bits tested by mikeb and jsing. raidframe bits tested by pea,
matthieu and naddy. The rest tested by at least thib, jsing and myself.

vector setup that has questionable features (that have, as far as I can
tell never been used in practice, atleast not in OpenBSD), remove all
the gunk and favor a simple struct full of function pointers that get
set directly by each of the filesystems.
Removes gobs of ugly code and makes things simpler by a magnitude.
The only downside of this is that we loose the vnoperate feature so
the spec/fifo operations of the filesystems need to be kept in sync
with specfs and fifofs, this is no big deal as the API it self is pretty
static.
Many thanks to armani@ who pulled an earlier version of this diff to
current after c2k10 and Gabriel Kihlman on tech@ for testing.
Liked by many. "come on, find your balls" deraadt@.

gets rid of #include <sys/dkio.h> in sys/ioctl.h and adds #include
<sys/dkio.h> to the places that actually want and use the disk
ioctls.
this became an issue when krw@'s X build failed when he was testing
a change to dkio.h.

eventhough this won't really harm as ext2fs doesn't handle files that large,
it was not correct.
no objections from thib@

as ext2fs doesn't support filesystems so large, it's more correct this way

Macro's that are nothing more then:

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

1) remove multiple size queues, introduced as a stopgap.
2) decouple pages containing data from their mappings
3) only keep buffers mapped when they actually have to be mapped
(right now, this is when buffers are B_BUSY)
4) New functions to make a buffer busy, and release the busy flag
(buf_acquire and buf_release)
5) Move high/low water marks and statistics counters into a structure
6) Add a sysctl to retrieve buffer cache statistics
Tested in several variants and beat upon by bob and art for a year. run
accidentally on henning's nfs server for a few months...

Zap all calls to simple_lock/unlock() on it (those calls are
#defined away though). Remove the LK_INTERLOCK from the calls
to vn_lock() and cleanup the filesystems wich implement VOP_LOCK().
(by remvoing the v_interlock from there calls to lockmgr()).
