8994ca3ce9 Removed statically configured mount type numbers (MOUNT_*) and all
references to them.

The change a couple of days ago to ignore these numbers in statically
configured vfsconf structs was slightly premature because the cd9660,
cfs, devfs, ext2fs, nfs vfs's still used MOUNT_* instead of the number
in their vfsconf struct.

79cc756d8b As described by the submitter:
Reverse the VFS_VRELE patch.  Reference counting of vnodes does not need
to be done per-fs.  I noticed this while fixing vfs layering violations.
Doing reference counting in generic code is also the preference cited by
John Heidemann in recent discussions with him.

The implementation of alternative vnode management per-fs is still a valid
requirement for some filesystems but will be revisited sometime later,
most likely using a different framework.

34bdbbd0de The intent is to get rid of WILLRELE in vnode_if.src by making
a complement to all ops that return a vpp, VFS_VRELE.  This is
initially only for file systems that implement the following ops
that do a WILLRELE:

	vop_create, vop_whiteout, vop_mknod, vop_remove, vop_link,
	vop_rename, vop_mkdir, vop_rmdir, vop_symlink

This is initial DNA that doesn't do anything yet.  VFS_VRELE is
implemented but not called.

A default vfs_vrele was created for fs implementations that use the
standard vnode management routines.

VFS_VRELE implementations were made for the following file systems:

Standard (vfs_vrele)
	ffs mfs nfs msdosfs devfs ext2fs

Custom
	union umapfs

Just EOPNOTSUPP
	fdesc procfs kernfs portal cd9660

These implementations may change as VOP changes are implemented.

In the next phase, in the vop implementations calls to vrele and the vrele
part of vput will be moved to the top layer vfs_vnops and made visible
to all layers.  vput will be replaced by unlock in these cases.  Unlocking
will still be done in the per fs layer but the refcount decrement will be
triggered at the top because it doesn't hurt to hold a vnode reference a
little longer.  This will have minimal impact on the structure of the
existing code.

This will only be done for vnode arguments that are released by the various
fs vop implementations.

Wider use of VFS_VRELE will likely require restructuring of the code.

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

57bf258e3d Fix all areas of the system (or at least all those in LINT) to avoid storing
socket addresses in mbufs.  (Socket buffers are the one exception.)  A number
of kernel APIs needed to get fixed in order to make this happen.  Also,
fix three protocol families which kept PCBs in mbufs to not malloc them
instead.  Delete some old compatibility cruft while we're at it, and add
some new routines in the in_cksum family.

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.

bbf3a56610 Add four more filesystem flags:
VFCF_NETWORK (this FS goes over the net)
	VFCF_READONLY (read-write mounts do not make any sense)
	VFCF_SYNTHETIC (data in this FS is not real)
	VFCF_LOOPBACK (this FS aliases something else)

cd9660 is readonly; nullfs, umapfs, and union are loopback; NFS is netowkr;
procfs, kernfs, and fdesc are synthetic.
