Separate the struct bio related stuff out of <sys/buf.h> into
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.

$Id$ -> $FreeBSD$

Silence warning about unused debug function. (I'll turn this function
into a DDB command in my next staticization sweep).

Don't use the strange null pointer constant `(ufs_daddr_t)0' in a call
to VOP_BMAP(). Don't use uncast NULLs in the same call.

Moved some #includes from <sys/param.h> nearer to where they are actually
used.

Removed unnecessary dependencies on KERNEL and DIAGNOSTIC. This was
more useful when opt_diagnostic.h had to be included.

Back out DIAGNOSTIC changes.

Turn DIAGNOSTIC into a new-style option.

Don't include <sys/lock.h> in headers when only `struct simplelock' is
required. Fixed everything that depended on the pollution.

Staticized.

Removed an unused #include in the `#ifdef KERNEL' case.

Fixed a comment to match the code. The code is still wrong
(ffs_checkoverlap() should be staticized and called from a
ddb command).

VFS mega cleanup commit (x/N)

1. Add new file "sys/kern/vfs_default.c" where default actions for
VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
POLL, REVOKE and STRATEGY. Various stuff spread over the entire
tree belongs here.

2. Change VOP_BLKATOFF to a normal function in cd9660.

3. Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC. These
are private interface functions between UFS and the underlying
storage manager layer (FFS/LFS/MFS/EXT2FS). The functions now
live in struct ufsmount instead.

4. Remove a kludge of VOP_ functions in all filesystems, that did
nothing but obscure the simplicity and break the expandability.
If a filesystem doesn't implement VOP_FOO, it shouldn't have an
entry for it in its vnops table. The system will try to DTRT
if it is not implemented. There are still some cruft left, but
the bulk of it is done.

5. Fix another VCALL in vfs_cache.c (thanks Bruce!)

Update a number of panic messages to reflect the actual name
of the routine that caused the panic.

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

Make ffs_subr.c compile when DIAGNOSTIC is defined.
It looks like this was broken before the Lite2 merge :-(.
VOP_BMAP was being called with the wrong number of arguments.

This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.
