MFC r264295:
Remove support of LUN-based CD changers from cd(4) driver.

This code was heavily broken few months ago during CAM locking changes.
Fixing it would require almost complete rewrite. Since there are no
known devices on market using this interface younger then ~15 years, and
they are CD, not even DVD, I don't see much reason to rewrite it.

This change does not mean those devices won't work. They will just work
slower due to inefficient disks load/unload schedule if several LUNs
accessed same time.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

none of the drivers in the tree support CDIOCCAPABILITY or CDIOCPITCH..
remove the documentation so people won't get confused and think they
are supported...

mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

Add links to cam(4).

First cut at documenting hw.cam.cd.retry_count. Moved
kern.cam.cd.%d.minimum_cmd_size to new SYSCTL VARIABLES section.

Sort sections.

Mechanically kill hard sentence breaks and double whitespaces.

Removed trailing whitespace.

mdoc(7): Use the new feature of the .In macro.

Move dynamic sysctl(8) variable creation for the cd(4) and da(4) drivers
out of cdregister() and daregister(), which are run from interrupt context.

The sysctl code does blocking mallocs (M_WAITOK), which causes problems
if malloc(9) actually needs to sleep.

The eventual fix for this issue will involve moving the CAM probe process
inside a kernel thread. For now, though, I have fixed the issue by moving
dynamic sysctl variable creation for these two drivers to a task queue
running in a kernel thread.

The existing task queues (taskqueue_swi and taskqueue_swi_giant) run in
software interrupt handlers, which wouldn't fix the problem at hand. So I
have created a new task queue, taskqueue_thread, that runs inside a kernel
thread. (It also runs outside of Giant -- clients must explicitly acquire
and release Giant in their taskqueue functions.)

scsi_cd.c: Remove sysctl variable creation code from cdregister(), and
move it to a new function, cdsysctlinit(). Queue
cdsysctlinit() to the taskqueue_thread taskqueue once we
have fully registered the cd(4) driver instance.

scsi_da.c: Remove sysctl variable creation code from daregister(), and
move it to move it to a new function, dasysctlinit().
Queue dasysctlinit() to the taskqueue_thread taskqueue once
we have fully registered the da(4) instance.

taskqueue.h: Declare the new taskqueue_thread taskqueue, update some
comments.

subr_taskqueue.c:
Create the new kernel thread taskqueue. This taskqueue
runs outside of Giant, so any functions queued to it would
need to explicitly acquire/release Giant if they need it.

cd.4: Update the cd(4) man page to talk about the minimum command
size sysctl/loader tunable. Also note that the changer
variables are available as loader tunables as well.

da.4: Update the da(4) man page to cover the retry_count,
default_timeout and minimum_cmd_size sysctl variables/loader
tunables. Remove references to /dev/r???, they aren't used
any longer.

cd.9: Update the cd(9) man page to describe the CD_Q_10_BYTE_ONLY
quirk.

taskqueue.9: Update the taskqueue(9) man page to describe the new thread
task queue, and the taskqueue_swi_giant queue.

Ispell sweep of share/man/man4.

Update man pages in the section 4 to match the reality in -CURRENT.

- Change lines referring to kernel configuration file:

Describe resource "hints" in /boot/device.hints.

- Try to describe resource allocation and probe/attach behavior in the
newbus framework.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

Fix misspelling of Julian's last name. Oops.

Update the cd(4) man page for the CAM cd driver.

This includes a description of the changer timeout kernel options and
sysctl variables. I didn't check to make sure the ioctl descriptions are
up to date; that will come sometime later. (The ioctls haven't changed in
the CAM driver, but I'm not sure if the man page was in sync with even the
old driver.)

Use the .Fx macro for FreeBSD references for releases prior to 2.0.
Use the .Tn macro for generic FreeBSD references. Cleanup other
formatting problems noticed while making the above changes.
