Refactoring done in r317703 broke -c, -l, and -L flags implying
suppression of match printing. Fortunately this is just a matter of not
doing any printing of the resulting matches and context printing was not
broken in this refactoring.
Add some regression tests since this area may still see further
refactoring, include different context flags as well even though they
were not broken in this case.

makefs(1) has a number of signedness warnings (when built with higher
WARNS), most of which can be addressed by careful application of casts
in makefs itself.
There is one case where a signedness warning arises from the blksize
macro, so must be addressed in the macro itself.

From user report, the errors are seen:
error 1
error 1
gptzfsboot: error 1 lba 4294967288
gptzfsboot: error 1 lba 1
gptzfsboot: no ZFS pools located, can't boot
The first two errors above are from issuing INT13 EAX=0x4800, meaning we
need to check if EDD is available and use EAX=0x800 if not.
For an workaround I'm using the similar idea as in biosdisk.c - first probe
ah=8h, then check if we have EDD.
Note we would like to see the correct disk size info, but we *may*
get away with anything >64MB, so we could at least test 2 zfs pool labels
on whole disk setup and not to freak out the INT13 interface.
If we get away with initial disk probing, then we have partition sizes from
the partition table and we should be able to complete the disk probing.
Note: this update does not provide full fix to all errors, but we get
the drvsize() errors removed.

After FreeBSD SVN revision 236814, the pass(4) driver changed from
only doing error recovery when the CAM_PASS_ERR_RECOVER flag was
set on a CCB to sometimes doing error recovery if the passed in
retry count was non-zero.
Error recovery would happen if two conditions were met:
1. The error recovery action was simply a retry. (Which is most
cases.)
2. The retry_count is non-zero. (Which happened a lot because of
cut-and-pasted code.)
This explains a bug I noticed in with camcontrol:
# camcontrol tur da34 -v
Unit is ready
# camcontrol reset da34
Reset of 1:172:0 was successful
At this point, there should be a Unit Attention:
# camcontrol tur da34 -v
Unit is ready
No Unit Attention.
Try it again:
# camcontrol reset da34
Reset of 1:172:0 was successful
Now set the retry_count to 0 for the TUR:
# camcontrol tur da34 -v -C 0
Unit is not ready
(pass42:mps1:0:172:0): TEST UNIT READY. CDB: 00 00 00 00 00 00
(pass42:mps1:0:172:0): CAM status: SCSI Status Error
(pass42:mps1:0:172:0): SCSI status: Check Condition
(pass42:mps1:0:172:0): SCSI sense: UNIT ATTENTION asc:29,2 (SCSI bus reset occurred)
(pass42:mps1:0:172:0): Field Replaceable Unit: 2
There is the unit attention. camcontrol(8) has a default
retry_count of 1, in case someone sets the -E flag without
setting -C.
The CAM_PASS_ERR_RECOVER behavior was only broken with the
CAMIOCOMMAND ioctl, which is the synchronous pass(4) API. It has
worked as intended (error recovery is only done when the flag
is set) in the asynchronous API (CAMIOQUEUE ioctl).

name and unit number in camcontrol(8).
Previously camcontrol(8) only supported rescanning or resetting
devices specified by bus:target:lun. This is because for
rescanning at least, you don't have a peripheral name and unit
number (e.g. da4) for devices that don't exist yet.
That is still the case after this change, but in other cases, when
the device does exist in the CAM EDT (Existing Device Table), we
do a careful lookup of the bus/target/lun if the user supplies a
peripheral name and unit number to find the bus:target:lun and then
issue the requested reset or rescan.
The lookup is done without actually opening the device in question,
since a rescan is often done to make a device go away after it has
been pulled. (This is especially true for busses/controllers, like
parallel SCSI controllers, that don't automatically detect changes
in topology.) Opening a device that is no longer there to
determine the bus/target/lun might result in error recovery actions
when the user really just wanted to make the device go away.
sbin/camcontrol/camcontrol.c:
In dorescan_or_reset(), if the use hasn't specified a
numeric argument, assume he has specified a device. Lookup
the pass(4) instance for that device using the transport
layer CAMGETPASSTHRU ioctl. If that is successful, we can
use the returned bus:target:lun to rescan or reset the
device.
Under the hood, resetting a device using XPT_RESET_DEV is
actually sent via the pass(4) device anyway. But this
provides a way for the user to specify devices in a more
convenient way, and can work on device rescans when the
device is going away, assuming it still exists in the EDT.
sbin/camcontrol/camcontrol.8:
Update the man page for the rescan and reset subcommands
to reflect that you can now use a device name and unit
number with them.

after pf_unload() so we end up trying to take locks which have been
