hannken | Make FSS_ERROR a flag to prevent bogus fscow_disestablish() after error.

hannken | Add two new states FSS_CREATING and FSS_DESTROYING and use them
while creating or destroying a snapshot.
Remove now unneeded sc_lock that made fss_ioctl mutually exclusive.
Fss_ioctl no longer blocks forever because a snapshot gets
created or destroyed.
Serialize snapshot creation and make it interruptible.

hannken | Convert flags FSS_ACTIVE and FSS_ERROR into new member sc_state
with states FSS_IDLE, FSS_ACTIVE and FSS_ERROR.

Complete backward compat with NetBSd 5.x: time_t changed size, so did
struct timeval, and so did struct fss_get. So we need a compat FSSIOCGET50
ioctl.

fss(4): Allow FSSIOCSET to set the initial flags. Add a new flag
"FSS_UNLINK_ON_CREATE" to unlink the backing store before
the snapshot gets created.
With this change dump(8) no longer dumps the zero-sized, but named
snapshot it is working on. Same applies to fsck_ffs(8).

Replace the fss unmount hook with a vfs_hook.
fssvar.h: struct device * -> device_t.
fss.c: establish unmount hook on first attach, remove on last detach.
vfs_syscalls.c: remove the call of fss_umount_hook().
vfs_trans.c: destroy cow handlers on unmount as fstrans_unmount() will be
called before vfs_hooks.

hannken | Create fss(4) devices on first open and destroy on last close of an
unconfigured device. That removes the compile-time constant number
of useable devices.
While here, add disk_busy()/disk_unbusy() instrumentation.

Update the file system copy-on-write handler.
- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

- change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

- Try to keep snapshot indirect blocks contiguous. This speeds up snapshot
creation by a factor of ~3 and reduces the file system suspension time by
a factor of ~5.
- Refine the scope of WAPBL transactions and the limit for deallocations in
one transaction so we should no longer get a "wapbl_flush: current
transaction too big to flush" panic when creating or removing snapshots
on larger logging disks.
- fss(4): Allow FSSIOCSET to set the initial flags. Add a new flag
"FSS_UNLINK_ON_CREATE" to unlink the backing store before the snapshot
gets created. With this change dump(8) no longer dumps the zero-sized,
