9626b608de 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.

bfbb9ce670 Divorce "dev_t" from the "major|minor" bitmap, which is now called
udev_t in the kernel but still called dev_t in userland.

Provide functions to manipulate both types:
        major()         umajor()
        minor()         uminor()
        makedev()       umakedev()
        dev2udev()      udev2dev()

For now they're functions, they will become in-line functions
after one of the next two steps in this process.

Return major/minor/makedev to macro-hood for userland.

Register a name in cdevsw[] for the "filedescriptor" driver.

In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.

In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits.  This will essentially
replace the current "alias" check code (same buck, bigger bang).

A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference.  If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.

Without DEVT_FASCIST I belive this patch is a no-op.

Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.

Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).

cec0f20ce7 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!)

596d40b9f4 Restored one line of "High Sierra" changes from rev.1.8.
The Lite2 changes in cd9660 are scarey.  I probably missed some
other lossage in this file.

996c772f58 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.

1130b656e5 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.

74ae43213c Moved the fsnode MALLOC to before the call to getnewvnode() so that the
process won't possibly block before filling in the fsnode pointer (v_data)
which might be dereferenced during a sync since the vnode is put on the
mnt_vnodelist by getnewvnode.

10dd32cd87 Added prototypes.
cd9660_rrip.c:
Added lots of bogus casts to hide type errors exposed by the prototypes.
(Different structs are assumed to have a common prefix.)

Finished staticizing.

988fa8efe3 Roll in my changes to make the cd9660 code understand the older
(original "High Sierra") CD format.  I've already implemented this for
1.1.5.1 (and posted to -hackers), but didn't get any response to it.
Perhaps i'm the only one who has such an old CD lying around...

Everything is done empirically, but i had three of them around (from
different vendors), so there's a high probability that i've got it
right. :)

that I don't have to worry about the latter when changing disklabel.h.

Supply prototypes for some functions that were implicitly declared and
