Minor improvements to the fwdownload code suggested by chs@:
o Print the path_id/target we're rescanning so it's not invisible
o No need for XPT_GDEVLIST, all the info is filled in. Remove sending it
as well as a comment related to it from a mistaken observation. libcam
always fills these in properly, so use those for the ccb path/target.
o Don't leak /dev/xpt fd in success cases.
o Rename fw_rescan_lun to fw_rescan_target and pass sim_mode to
only print path_id and target_id info.

After downloading the firmware to a device, it's inquiry data likely
will change. Force a rescan of the target with the CAM_EXPECT_INQ_CHANGE
flag to get it to record the new inqury data as being expected. This
avoids the need for a 'camcontrol rescan' on the device which detaches
and re-attaches the disk (da, ada) device. This brings fwdownload up to
nvmecontrol's ability to do the same thing w/o changing the exposed
nvme/nvd/nda device. We scan the target and not the LUN because dual
actuator drives have multiple LUNs, but the firmware is global across
many vendors' drives (and the so far theoretical ones that aren't won't
be harmed by the rescan).
Since the underlying struct disk is now preserved accross this
operation, it's now possible to upgrade firmware of a root device w/o
crashing the system. On systems that are quite busy, the worst that
happens is that certain operaions are reported cancelled when the new
firmware is activated. These operations are retried with the normal CAM
recovery mechanisms and will work on the retry. The only visible hiccup
is the time that new firmware is flashing / initializing. One should not
consider this operation completely risk free, however, since not all
drives are well behaved after a firmware download.

Implement and document the new depop command. This command manages drive elements
for drives that support it. Storage elements are typically heads. Element status
can be discovered. Elements may be removed or restored. And the status of any
current depop operation can be assessed.
depop -d elm will remove element elm and truncate available capacity.
depop -l will list the current drive elements and their current status.
depop -r elm will try to restore all retired elements and rebuild capacity.
Changing storage elements may reinitialize the drive. This operation will lose
data and may take hours to complete. Use the drive provided timeout for
operations by default.

- Remove incomplete and dangerous ata_res decoding from ata_do_cmd().
Instead switch all functions that need the result to use get_ata_status(),
doing the same, but more careful, also reducing code duplication.
- Made get_ata_status() to also decode fixed format sense. In many cases
it is still not enough to make it useful, since it can only report results
of 28-bit command, but it is slightly better then nothing.
- Organize error reporting in ata_do_cmd(), so that if caller specified
AP_FLAG_CHK_COND, it is responsible for command errors (non-ioctl ones).
- Make HPA/AMA errors not fatal for `identify` subcommand.
- Fix reprobe() not being called on HPA/AMA when in quiet mode.
- Remove not very useful messages from `format` and `sanitize` commands
with -y flag. Once they started, they often can't be stopped any way.

This is a rework of r344701, that noticed that number of bytes passes to
8 bit sector count field gets truncated. First decision was to not pass
anything, since ATA specs define the field as N/A. But it appeared to be a
problem for some SAT devices, that require information about data transfer
to operate properly. Some additional investigation shown that it is quite
a common practice to set unused fields of ATA commands (fortunately ATA
specs formally allow it) to supply the information to SAT layer. I have
found SAS-SATA interposer that does not allow pass-through without it.
As side effect, reduce code duplication by removing ata_do_28bit_cmd()
function, replacing it with more universal ata_do_cmd().

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.

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

gcc hates dt < CC_DT_NONE since it can never be true when dt is an unsigned
type. Since that's a compiler choice and may be affected by weird stuff, instead
use (unsigned)dt > CC_DT_UNKNOWN to test for bounds error since that will work
regardless of the signedness of dt.

update to support raw nand. This code has been off by default for

HGST was bought by WDC. Over the years, it has sold different drives
branded as HGST, WD or WDC. All of them need the HGST workaround of
sending 4k-sized packets (or multiples of 4k). And the ones that don't
really need this aren't broken by this change. Submitter is the vendor
who has tested these changes on a number of drives. I've simplified it
slightly, since we don't need additional vendors for this at this
