Remove clause 3 and 4 from TNF licenses

use aprint_*_dev and device_xname

Merge disk init changes from the vmlocking branch. These seperate init /
destroy of 'struct disk' from attach / detach.

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoev

B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

Complete initializers, teach drivers that we moved from struct proc to
struct lwp, sprinkle some needed const qualifiers.

integrate kauth.

Make i/o statistics collection more generic, include tape drives and
nfs mounts in the set of devices that statistics will be reported on.

Use device_private().

Use device_unit().

Use device_parent().

Fix some typos.

merge ktrace-lwp.

- 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.

- 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.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)

nuke trailing whitespace

move buffer queue related stuffs from buf.h to their own header, bufq.h.

Remove the last vestiges of COMPAT_NOLABEL. It's been 10 years; label
your disks already.

Move UCB-licensed code from 4-clause to 3-clause licence.
