When building on native dev system, there are no issues but when
cross-compiling for target system, some linker errors are observed.
The only way to avoid these errors is by adjusting the Makefile.am
of those various components to add the library dependencies.

This commit refactors the systemd mount generators and makes the
following major changes:
- The generator now generates units for datasets marked canmount=noauto,
too. These units are NOT WantedBy local-fs.target.
If there are multiple noauto datasets for a path, no noauto unit will
be created. Datasets with canmount=on are prioritized.
- Introduces handling of new user properties which are now included in
the zfs-list.cache files:
- org.openzfs.systemd:requires:
List of units to require for this mount unit
- org.openzfs.systemd:requires-mounts-for:
List of mounts to require by this mount unit

zed core dumps due to a NULL pointer in zfs_agent_iter_vdev(). The
gs_devid is NULL, but the nvl has a "devid" entry.
zfs_agent_post_event() checks that ZFS_EV_VDEV_GUID or DEV_IDENTIFIER is
present in nvl, but then later it and zfs_agent_iter_vdev() assume that
DEV_IDENTIFIER is present and thus gs_devid is set.
Typically this is not a problem because usually either all vdevs have
devid's, or none of them do. Since zfs_agent_iter_vdev() first checks if
the vdev has devid before dereferencing gs_devid, the problem isn't
typically encountered. However, if some vdevs have devid's and some do
not, then the problem is easily reproduced. This can happen if the pool
has been moved from a system that has devid's to one that does not.
The fix is for zfs_agent_iter_vdev() to only try to match the devid's if
both nvl and gsp have devid's present.

The root cause of these failures is that udev can notify the
ZED of newly created partition before its links are created.
Handle this by allowing an auto-replace to briefly wait until
udev confirms the links exist.
Distill this test case down to its essentials so it can be run
reliably. What we need to check is that:
1) A new disk, in the same physical location, is automatically
brought online when added to the system,
2) It completes the replacement process, and
3) The pool is now ONLINE and healthy.
There is no need to remove the scsi_debug module. After exporting
the pool the disk can be zeroed, removed, and then re-added to the
system as a new disk.

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.

OpenZFS provides a library called tpool which implements thread
pools for user space applications. Porting this library means
the zpool utility no longer needs to borrow the kernel mutex and
taskq interfaces from libzpool. This code was updated to use
the tpool library which behaves in a very similar fashion.
Porting libtpool was relatively straight forward and minimal
modifications were needed. The core changes were:
* Fully convert the library to use pthreads.
* Updated signal handling.
* lmalloc/lfree converted to calloc/free
* Implemented portable pthread_attr_clone() function.
Finally, update the build system such that libzpool.so is no
longer linked in to zfs(8), zpool(8), etc. All that is required
is libzfs to which the zcommon soures were added (which is the way
it always should have been). Removing the libzpool dependency
resulted in several build issues which needed to be resolved.
* Moved zfeature support to module/zcommon/zfeature_common.c

Also included are updates to auto-online test
Automated auto-replace test to go along with ZED FMA integration
(PR 4673) auto-replace_001.pos works using a scsi_debug device
(the only usable virtual device currently due to whole_disk var
needing to be set)
Functionality for automated FMA auto-replace test to work with
scsi_debug devs: Some functionality/exceptions needed to be
added for automation of auto-replace to work correctly.
In the test an alias vdev_id rule is added for any scsi_debug
device which sets the phys_path="scsidebug" after a udevadm
trigger command.
A symlink is created for the vdev_id.conf file (in /etc/zfs/ by
default) to be used in-tree for the test suite
(/var/tmp/zfs/vdev_id.conf). "./scripts/zfs-helpers.sh -i" needs
to be run before fault tests in the ZTS (to use udev rules in-tree)

Add trivial libzfs_fru_compare() function which can be used when

If the LED is being accessed by another process when we try to update
it, the update will be lost. Add a retry loop which will read the state
of the LED and update it until the LED is in the correct state. The
number of times this will occur is limited to ensure that the ZEDlet
won't hang ZED.
Refactor to remove duplication so setting of the LED occurs in only one
place.
Cleanup a couple of the warnings generated by shellcheck which weren't
the result of specific choices by the author. Several notes and warnings
are still present but removing them would make the code less clear or
require adding lines to tell shellcheck to ignore the warning.
Remove ",i" from the documentation at the top of the file which appears
to be a typographic error.

This patch adds a command (-c) option to zpool status and zpool iostat. The
-c option allows you to run an arbitrary command on each vdev and display
the first line of output in zpool status/iostat. The environment vars
VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path"
before running the command. For device mapper, multipath, or partitioned
vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful
if the command you're running requires a /dev/sd* device.
The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device
instead of using libdevmapper. This not only removes the libdevmapper
requirement at build time, but also allows you to resolve device mapper
devices without being root. This means that UDEV_UPATH get set correctly
when running zpool status/iostat as an unprivileged user.
Example:
$ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH'
NAME STATE READ WRITE CKSUM
mypool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
mpatha ONLINE 0 0 0 I am /dev/mapper/mpatha, /dev/sdc

The phase 2 work primarily entails the Diagnosis Engine and
the Retire Agent modules. It also includes infrastructure
to support a crude FMD environment to host these modules.
The Diagnosis Engine consumes I/O and checksum ereports and
feeds them into a SERD engine which will generate a corres-
ponding fault diagnosis when the SERD engine fires. All the
diagnosis state data is collected into cases, one case per
vdev being tracked.
The Retire Agent responds to diagnosed faults by isolating
the faulty VDEV. It will notify the ZFS kernel module of
the new VDEV state (degraded or faulted). This agent is
also responsible for managing hot spares across pools.
When it encounters a device fault or a device removal it
replaces the device with an appropriate spare if available.

The previous autoreplace code assumed that if you were using autoreplace, then
you also had the enclosure SES driver loaded. This could lead to autoreplace
not working if the SES driver wasn't loaded, or if it wasn't creating the
proper enclosure_device symlinks (which has happened). This patch removes
that assumption.
