Added check for broken alien version
Added a check for alien 8.95.{1,2,3}, which is known to fail to 
generate debs 100% of the time, and instead print out a message 
informing the developer that it's known to be broken and linking 
them to more information.

Use dsl_scan_setup_check() to setup a scrub
When a rebuild completes it will automatically schedule a follow up
scrub to verify all of the block checksums.  Before setting up the
scrub execute the counterpart dsl_scan_setup_check() function to
confirm the scrub can be started.  Prior to this change we'd only
check vdev_rebuild_active() which isn't as comprehensive, and using
the check function keeps all of this logic in one place.

ZTS: Tests using zhack may fail on FreeBSD
As described in #11854, zhack is occasionally segfaulting on FreeBSD. 
Debugging this is proving to be tricky. To avoid false positives in
the CI add entries for the tests that use zhack in zts-report to 
accept that they may occasionally fail on FreeBSD.

наб 64c03a0a27 zed: implement close_from() in terms of /proc/self/fd, if available
/dev/fd on Darwin

Consider the following strace output:
  prlimit64(0, RLIMIT_NOFILE, NULL, {rlim_cur=1024, rlim_max=1024*1024}) = 0

Yes, that is well over a million file descriptors!

This reduces the ZED start-up time from "at least a second" to
"instantaneous", and, under strace, from "don't even try" to "usable"
by simple virtue of doing five syscalls instead of over a million;
in most cases the main loop does nothing

Recent Linuxes (5.8+) have close_range(2) for this, but that's an
overoptimisation (and libcs don't have wrappers for it yet)

This is also run by the ZEDLET pre-exec. Compare:
  Finished "all-syslog.sh" eid=13 pid=6717 time=1.027100s exit=0
  Finished "history_event-zfs-list-cacher.sh" eid=13 pid=6718 time=1.046923s exit=0

наб aa5a4eb5d0 i-t: don't brokenly set the scheduler for root pool vdev's disks
This effectively reverts
  4fc411f7a3 (part of #6807) and
  f6fbe25664 (#9042) ‒
the code itself and latter PR cite symmetry with whole-disk-vdev
behaviour (presumably because rootfs vdevs are rarely whole disks),
but the code is broken for NVME devices (indeed, it'd strip the
controller number instead of the (potential) partition number, turning
"nvme0n1p1" into "nvmen1p1", which would then subsequently fail the
sysfs existence check); it could be fixed to handle those (and any
others) rather easily by dereferencing /sys/class/block/$devname,
but this isn't the place for setting this ‒ as noted in the commit that
removed setting the scheduler by default
(9e17e6f254) ‒ use an udev rule

kmem_alloc(KM_SLEEP) should use kvmalloc()
`kmem_alloc(size>PAGESIZE, KM_SLEEP)` is backed by `kmalloc()`, which
finds contiguous physical memory.  If there isn't enough contiguous
physical memory available (e.g. due to physical page fragmentation), the
OOM killer will be invoked to make more memory available.  This is not
ideal because processes may be killed when there is still plenty of free
memory (it just happens to be in individual pages, not contiguous runs
of pages).  We have observed this when allocating the ~13KB `zfs_cmd_t`,
for example in `zfsdev_ioctl()`.

This commit changes the behavior of
`kmem_alloc(size>PAGESIZE, KM_SLEEP)` when there are insufficient
contiguous free pages.  In this case we will find individual pages and
stitch them together using virtual memory.  This is accomplished by
using `kvmalloc()`, which implements the described behavior by trying
`kmalloc(__GFP_NORETRY)` and falling back on `vmalloc()`.

The behavior of `kmem_alloc(KM_NOSLEEP)` is not changed; it continues to
use `kmalloc(GPF_ATOMIC | __GFP_NORETRY)`.  This is because `vmalloc()`
may sleep.

ZTS: pool_checkpoint improvements
The pool_checkpoint tests may incorrectly fail because several of
them invoke zdb for an imported pool.  In this scenario it's not
unexpected for zdb to fail if the pool is modified.  To resolve
this these zdb checks are now done after the pool has been exported.

Additionally, the default cleanup functions assumed the pool would
be imported when they were run.  If this was not the case they're
exit early and fail to cleanup all of the test state causing
subsequent tests to fail.  Add a check to only destroy the pool
when it is imported.

CI: Increase free space in workflow
Recently we've been running out of free space in the ubuntu 20.04
environment resulting in test failures.  This appears to be caused
by a change in the default available free space and not because of
any change in OpenZFS. Try and avoid this failure by applying a
suggested workaround which removes some unnecessary files.

Fixing m4 iops rename check
The configure check for iops->rename wanting flags was missing the
AC_MSG_CHECKING() so it would just print yes without saying what was

health=faulted && dataset in /etc/fstab => 8/"Operational error"
pool not found => 8/"Operational error"

Add compatibility file sets (ZoL 0.6.1, 0.6.4, OpenZFS 2.1)
ZoL 0.6.1 introduced feature flags with the three features that all
implementations at the time were guaranteed to have.  0.6.4 introduced
a few more until 0.6.5 added two after that.  OpenZFS 2.1 added the
dRAID feature.

Use a helper function to clarify gang block size
For gang blocks, `DVA_GET_ASIZE()` is the total space allocated for the
gang DVA including its children BP's.  The space allocated at each DVA's
vdev/offset is `vdev_psize_to_asize(vd, SPA_GANGBLOCKSIZE)`.

This commit makes this relationship more clear by using a helper
function, `vdev_gang_header_asize()`, for the space allocated at the
gang block's vdev/offset.

When specifying raidz vdev name, parity count should match
When specifying the name of a RAIDZ vdev on the command line, it can be
specified as raidz-<vdevID> or raidzP-<vdevID>.
e.g. `zpool clear poolname raidz-0` or `zpool clear poolname raidz2-0`

If the parity is specified in the vdev name, it should match the actual
parity of that RAIDZ vdev, otherwise the command should fail.  This
commit makes it so.
