The second part of list_file_blocks transforms the object description
output by zdb -ddddd $ds $objnum into a stream of lines of the form
"level path offset length" for the indirect blocks in the given file.
The current code only works for the first copy of L0 blocks. L1 and
L2 indirect blocks have more than one copy on disk.
Add one more -d to the zdb command so we get all block copies and
rewrite the transformation to match more than L0 and output all DVAs.

The first part of list_file_blocks transforms the pool configuration
output by zdb -C $pool into shell code to set up a shell variable,
VDEV_MAP, that maps from vdev id to the underlying vdev path. This
variable is a simple indexed array. However, the vdev id in a DVA is
only the id of the top level vdev.
When the pool is mirrored, the top level vdev is a mirror and its
children are the mirrored devices. So, what we need is to map from
the top level vdev id to a list of the underlying vdev paths.
ist_file_blocks does not need to work for raidz vdevs, so we can
disregard that case.

FreeBSD doesn't have an equivalent to udevadm settle, so we have been
resorting to a three second sleep to wait for device changes to take
effect. This is far from ideal.
We are mainly waiting for volmode=geom zvols to appear in /dev, so as
a hack, reading the geom config will have the desired effect of
quiescing the geom state.

FreeBSD stat uses -f to specify the format string rather than -c.
list_file_blocks in blkdev.shlib uses stat -c %i to get a file's
object ID for zdb. We already have a library function to do this
portably.
Use get_objnum to get the file's object ID.
Take log_must off of the call to list_free_blocks in
corrupt_blocks_at_level, which had masked the error. It was not good

The horrible effects of human slavery continue to impact society. The
casual use of the term "slave" in computer software is an unnecessary
reference to a painful human experience.
This commit removes all possible references to the term "slave".
Implementation notes:
The zpool.d/slaves script is renamed to dm-deps, which uses the same
terminology as `dmsetup deps`.
References to the `/sys/class/block/$dev/slaves` directory remain. This
directory name is determined by the Linux kernel. Although
`dmsetup deps` provides the same information, it unfortunately requires
elevated privileges, whereas the `/sys/...` directory is world-readable.

While the autoexpand property may seem like a small feature it
depends on a significant amount of system infrastructure. Enough
of that infrastructure is now in place that with a few modifications
for Linux it can be supported.
Auto-expand works as follows; when a block device is modified
(re-sized, closed after being open r/w, etc) a change uevent is
generated for udev. The ZED, which is monitoring udev events,
passes the change event along to zfs_deliver_dle() if the disk
or partition contains a zfs_member as identified by blkid.
From here the device is matched against all imported pool vdevs
using the vdev_guid which was read from the label by blkid. If
a match is found the ZED reopens the pool vdev. This re-opening
is important because it allows the vdev to be briefly closed so
the disk partition table can be re-read. Otherwise, it wouldn't
be possible to report the maximum possible expansion size.
Finally, if the property autoexpand=on a vdev expansion will be
attempted. After performing some sanity checks on the disk to
verify that it is safe to expand, the primary partition (-part1)
will be expanded and the partition table updated. The partition
is then re-opened (again) to detect the updated size which allows
the new capacity to be used.
In order to make all of the above possible the following changes
were required:
* Updated the zpool_expand_001_pos and zpool_expand_003_pos tests.
These tests now create a pool which is layered on a loopback,
scsi_debug, and file vdev. This allows for testing of non-
partitioned block device (loopback), a partition block device
(scsi_debug), and a file which does not receive udev change
events. This provided for better test coverage, and by removing
the layering on ZFS volumes there issues surrounding layering
one pool on another are avoided.
* zpool_find_vdev_by_physpath() updated to accept a vdev guid.
This allows for matching by guid rather than path which is a
more reliable way for the ZED to reference a vdev.
* Fixed zfs_zevent_wait() signal handling which could result
in the ZED spinning when a signal was not handled.
* Removed vdev_disk_rrpart() functionality which can be abandoned
in favor of kernel provided blkdev_reread_part() function.
* Added a rwlock which is held as a writer while a disk is being
reopened. This is important to prevent errors from occurring
for any configuration related IOs which bypass the SCL_ZIO lock.
The zpool_reopen_007_pos.ksh test case was added to verify IO
error are never observed when reopening. This is not expected
to impact IO performance.
Additional fixes which aren't critical but were discovered and
resolved in the course of developing this functionality.
* Added PHYS_PATH="/dev/zvol/dataset" to the vdev configuration for
ZFS volumes. This is as good as a unique physical path, while the
volumes are not used in the test cases anymore for other reasons
this improvement was included.
