Make `camcontrol modepage` support block descriptors.

It allows to read and write block descriptors alike to mode page parameters.
It allows to change block size or short-stroke HDDs or overprovision SSDs.
Depenting on -P parameter the change can be either persistent or till reset.
In case of block size change device may need reformat after the setting.
In case of SSD overprovisioning format or sanitize may be needed to really
free the flash.

During implementation appeared that csio_encode_visit() can not handle
integers of more then 4 bytes, that makes 8-byte LBA handling awkward.
I had to split it into two 4-byte halves now.

Make `camcontrol modepage` to use 10 byte commands.

While old devices may not support 10 byte MODE SENSE/MODE SELECT commands,
new ones may not be able to report all mode pages with 6 byte commands.

This patch makes camcontrol by default start with 10 byte commands and
fall back to 6 byte on ILLEGAL REQUEST error, or 6 byte can be forced.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

When editing a mode page on a tape drive, do not clear the device
specific parameter.

Tape drives include write protect (WP), Buffered Mode and Speed
settings in the device-specific parameter. Clearing this
parameter on a mode select can have the effect of turning off
write protect or buffered mode, or changing the speed setting of
the tape drive.

Disks report DPO/FUA support via the device specific parameter
for MODE SENSE, but the bit is reserved for MODE SELECT. So we
clear this for disks (and other non-tape devices) to avoid
potential errors from the target device.

sbin/camcontrol/modeedit.c:
Clear the device-specific parameter in the mode page
header if we're not operating on a tape drive.

Add task attribute support to camcontrol(8).

Users can use the new generic argument, -Q task_attr, to specify a task
attribute (simple, ordered, head of queue, aca) for the commands issued.
The the default is simple, which works with all SCSI devices that support
tagged queueing.

This will mostly be useful for debugging target behavior in certain
situations.

You can try it out by compiling CTL with CTL_IO_DELAY turned on (in
sys/cam/ctl/ctl_io.h) and then do something like this with one of the CTL
LUNs:

ctladm delay 0:0 -l done -t 10
camcontrol tur da34 -v

And at then before the 10 second timer is up, in another terminal:

camcontrol inquiry da34 -Q ordered -v

The Inquiry should complete just after the TUR completes. Ordinarily
it would complete first because of the delay injection, but because the
task attribute is set to ordered in this case, CTL holds it up until the
previous command has completed.

sbin/camcontrol/camcontrol.c:
Add the new generic argument, -Q, which allows the user to specify
a SCSI task attribute. The user can specify task attributes by
name or numerically.

Add a new task_attr arguments to SCSI sub-functions.
