Create the kern.ccd sysctl sub-tree when built as a module. Even though
the contents of the sub-tree are all structures, and thus not displayed
via sysctl(8), the info is potentially useful to programs. (For example,
ccdconfig could use this to determine how many units are available.)

The sub-tree is already available when the module is included as built-in
module.

pointers.

We have three sets of DTYPE_ constants in the kernel:
altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.

Centralize wedge ioctls in disk_ioctl.

destroy the pool and the mutex when detaching.

- only create ccd's when we ask them to be created.
- keep track of the number of active ccd's so that we don't modunload and
crash
- fix formatting.
- don't attach 4, the argument is not used.

Fix locking error.
Clear EPASSTHROUGH return value from disk_ioctl.
Add missing wedge ioctls.

Slowly bring this thing kicking and screaming into the 21st century:

- use struct disk_geom
- add wedge support

call disk_ioctl.

No longer warn about differences bewteen disk size and total sector count
in disklabel when the latter is just clamped to the maximum.

clamp total number of sectors to UINT32_MAX instead of providing the
lower 32bit of the 64bit number.

Switch size_t to uint64_t in appropriate places to ensure that ccd(4) works
with component and total sizes of > 2TB.
Add COMPAT_60 code for platforms where this alters userland-accessible
structures.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

Add d_discard to all struct bdevsw instances I could find.

I've set them all to nodiscard. Some of them (wd, dk, vnd, ld,
raidframe, maybe cgd) should be implemented for real.

Change dk_lookup() to return an anonymous vnode not associated with
any file system. Change all consumers of dk_lookup() to get the
device from "v_rdev" instead of VOP_GETATTR() as specfs does not
support VOP_GETATTR(). Devices obtained with dk_lookup() will no
longer disappear on forced unmounts.

ccd module also needs dk_subr

- no limit on the number of ccd devices.
- provide sysctl for getting information.
