Issue #4034
When creating and destroying pools in tight loop it's possible to
exhaust the number of allowed threads on a system. This results
in taskq_create() failling and a NULL dereference.
Resolve the issue by falling back to opening the vdevs all
synchronously.

Previously when a drive faulted, the statechange-led.sh script would lookup
the drive's LED sysfs entry in /sys/block/sd*/device/enclosure_device, and
turn it on. During testing we noticed that if you pulled out a drive, or if
the drive was so badly broken that it no longer appeared to Linux, that the
/sys/block/sd* path would be removed, and the script could not lookup the
LED entry.
To fix this, this patch looks up the disks's more persistent
"/sys/class/enclosure/X:X:X:X/Slot N" LED sysfs path at pool import. It then
passes that path to the statechange-led script to use, rather than having the
script look it up on the fly. This allows the script to turn on/off the slot
LEDs even when the drive is missing.

test-runner should be creating the current symlink in the
directory above the output directory. In a previous commit,
the current symlink was placed in the current working
directory, which could be inaccessible. It is more likely
that the output directory is always accessible.
This is needed because without this there's no deterministic
way to get the path to ZFS Test Suite results until after the
test suite has started. This makes it difficult for buildbot to
follow the log file.

The AVL tree compare function requires that either -1, 0, or 1 be
returned. However the strcmp() function only guarantees that a
negative, zero, or positive value is returned. Therefore, the
return value of strcmp() needs to be sanitized with AVL_ISIGN.
This was initially overlooked because the x86_64 implementation
of strcmp() happens to only returns the allowed values. This
was observed on an aarch64 platform which behaves correctly but
differently as described above.

When Dracut starts up, it needs to determine whether a pool will remain
"hanging open" before the system shuts off. In such a case, then the
code to clean up the pool (using the previous export -F work) must
be invoked. Since Dracut has had a recent change that makes
mount-zfs.sh simply not run when the root dataset is already mounted,
we must use the cleanup hook to order Dracut to do shutdown cleanup.

In this test the 'ls -ls' command was used to print testfile size in
blocks. Because the environment variable BLOCK_SIZE was set
the 'ls -ls' command detected this and output its block count as the

the -k was was added to force ls to return 1k blocks. This has the
additional advantage of behaving consistently across platforms.

When write I/Os are issued, they are issued in block order but the ZIO
pipeline will drive them asynchronously through the allocation stage
which can result in blocks being allocated out-of-order. It would be
nice to preserve as much of the logical order as possible.
In addition, the allocations are equally scattered across all top-level
VDEVs but not all top-level VDEVs are created equally. The pipeline
should be able to detect devices that are more capable of handling
allocations and should allocate more blocks to those devices. This
allows for dynamic allocation distribution when devices are imbalanced
as fuller devices will tend to be slower than empty devices.
The change includes a new pool-wide allocation queue which would
throttle and order allocations in the ZIO pipeline. The queue would be
ordered by issued time and offset and would provide an initial amount of
allocation of work to each top-level vdev. The allocation logic utilizes
a reservation system to reserve allocations that will be performed by
the allocator. Once an allocation is successfully completed it's
scheduled on a given top-level vdev. Each top-level vdev maintains a
maximum number of allocations that it can handle (mg_alloc_queue_depth).
The pool-wide reserved allocations (top-levels * mg_alloc_queue_depth)
are distributed across the top-level vdevs metaslab groups and round
robin across all eligible metaslab groups to distribute the work. As
top-levels complete their work, they receive additional work from the
pool-wide allocation queue until the allocation queue is emptied.
