e2cbb31311 Make the vnode opv vector construction fully dynamic. Previously we
leaked memory on each unload and were limited to items referenced in
the kernel copy of vnode_if.c.  Now a kernel module is free to create
it's own VOP_FOO() routines and the rest of the system will happily
deal with it, including passthrough layers like union/umap/etc.

Have VFS_SET() call a common vfs_modevent() handler rather than
inline duplicating the common code all over the place.

Have VNODEOP_SET() have the vnodeops removed at unload time (assuming a
module) so that the vop_t ** vector is reclaimed.

Slightly adjust the vop_t ** vectors so that calling slot 0 is a panic
rather than a page fault.  This could happen if VOP_something() was called
without *any* handlers being present anywhere (including in vfs_default.c).
slot 1 becomes the default vector for the vnodeop table.

TODO: reclaim zones on unload (eg: nfs code)

4363221ba2 VOP_STRATEGY grows an (struct vnode *) argument
as the value in b_vp is often not really what you want.
(and needs to be frobbed). more cleanups will follow this.

94b6d72794 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

5c21be3db6 Don't #include vm stuff in vnode_if.[ch]. Enough vm stuff (a
single typedef) is now declared in <sys/types.h>.

This is the first of 4 commits that will remove some excessive
includes of vm*.h and user.h.  The total speed improvement isn't
as large as I first thought.  `make depend; make' for LINT only
improved from 2180 seconds to 2108 seconds user time.

88d6fa4d4a Second batch of cleanup changes.
This time mostly making a lot of things static and some unused
variables here and there.

4de4f43cd0 Generate prototypes for VOP functions. I decided to keep the old-style
definitions even though the functions are inline.  If vnode_if.h was
compiled by a non-ANSI compiler, then `inline' would be defined away,
so vnode_if.h might compile correctly.

251a16a6af Added VOP_GETPAGES/VOP_PUTPAGES and also the "backwards" block count
for VOP_BMAP.  Updated affected filesystems...

21cc29328e Removed my special-case hack for VOP_LINK and fixed the problem with the
wrong vp's ops vector being used by changing the VOP_LINK's argument order.
The special-case hack doesn't go far enough and breaks the generic
bypass routine used in some non-leaf filesystems. Pointed out by Kirk
McKusick.

0c5108c021 The generated VCALL always uses the first vp which in the case of /link/
might not be handled by the same FS as the directory (e.g. special device
files)...so it must be special-cased. This bug is seen when doing
"ln /dev/console /dev/foo" or equivilent and first appeared after I fixed
the argument order of VOP_LINK.  YUCK! There really needs to be a way of
specifying what vp to use in the VCALL; doing this could fix the strategy
and bwrite special-cases, too.
