Added uncompress requirement
Having an old enough version of "file" and no "uncompress" program
installed can cause rpmbuild as root to crash and mangle rpmdb.

So let's add a build dependency for RPM-based systems.

Commit 86b5f4c12 added a new zfs_clone_livelist_dedup.ksh test case
but didn't include it in the Makefile.am.  This results in the test
not being included in the dist tarball so it's never run by the CI.

Remove pool io kstats (#12212)
This mostly reverts "3537 want pool io kstats" commit of 8 years ago.

From one side this code using pool-wide locks became pretty bad for
performance, creating significant lock contention in I/O pipeline.
From another, there are more efficient ways now to obtain detailed
statistics, while this statistics is illumos-specific and much less
usable on Linux and FreeBSD, reported only via procfs/sysctls.

This commit does not remove KSTAT_TYPE_IO implementation, that may
be removed later together with already unused KSTAT_TYPE_INTR and
KSTAT_TYPE_TIMER.

Correct a flaw in the Python 3 version checking
It turns out the ax_python_devel.m4 version check assumes that
("3.X+1.0" >= "3.X.0") is True in Python, which is not when X+1
is 10 or above and X is not. (Also presumably X+1=100 and ...)

So let's remake the check to behave consistently, using the
"packaging" or (if absent) the "distlib" modules.

(Also, update the Github workflows to use the new packages.)

libzfs: On FreeBSD, use MNT_NOWAIT with getfsstat
`getfsstat(2)` is used to retrieve the list of mounted file systems,
which libzfs uses when fetching properties like mountpoint, atime,
setuid, etc.  The `mode` parameter may be `MNT_NOWAIT`, which uses
information in the VFS's cache, or `MNT_WAIT`, which effectively does a
`statfs` on every single mounted file system in order to fetch the most
up-to-date information.  As far as I can tell, the only fields that
libzfs cares about are the filesystem's name, mountpoint, fstypename,
and mount flags.  Those things are always updated on mount and unmount,
so they will always be accurate in the VFS's mount cache except in two
circumstances:

1) When a file system is busy unmounting
2) When a ZFS file system changes the value of a mount-overridable
   property like atime or setuid, but doesn't remount the file system.
   Right now that only happens when the property is changed by an
   unprivileged user who has delegated authority to change the property
   but not to mount the dataset.  But perhaps libzfs could choose to do
   it for other reasons in the future.

Switching to `MNT_NOWAIT` will greatly improve speed with no downside,
as long as we explicitly update the mount cache whenever we change a
mount-overridable property.

For comparison, Illumos gets this information using the native
`getmntany` and `getmntent` functions, which also use cached
information.  The illumos function that would refresh the cache,
`resetmnttab`, is never called by libzfs.

And on GNU/Linux, `getmntany` and `getmntent` don't even communicate
with the kernel directly.  They simply parse the file they are given,
which is usually /etc/mtab or /proc/mounts.  Perhaps the implementation
of /proc/mounts is synchronous, ala MNT_WAIT; I don't know.

More aggsum optimizations
- Avoid atomic_add() when updating as_lower_bound/as_upper_bound.
Previous code was excessively strong on 64bit systems while not
strong enough on 32bit ones.  Instead introduce and use real
atomic_load() and atomic_store() operations, just an assignments
on 64bit machines, but using proper atomics on 32bit ones to avoid
torn reads/writes.

 - Reduce number of buckets on large systems.  Extra buckets not as
much improve add speed, as hurt reads.  Unlike wmsum for aggsum
reads are still important.

Since it should always be safe to continue, let's relax about all

FreeBSD: incorporate changes to the VFS_QUOTACTL(9) KPI
VFS_QUOTACTL(9) has been updated to allow each filesystem to indicate
whether it has changed the busy state of the mount.  The filesystem
may still assume that its .vfs_quotactl entrypoint is always called
with the mount busied, but only needs to unbusy the mount (and clear
*mp_busy) if it does something that actually requires the mount to be
unbusied.  It no longer needs to blindly copy-paste the UFS protocol
for calling vfs_unbusy(9) for the Q_QUOTAOFF and Q_QUOTAON commands.

Fix error check in nvlist_print_json_string
Move check for errors from mbrtowc() into the loop.  The error values
are not actually negative, so we don't break out of the loop when they

Linux: Set spl_kmem_cache_slab_limit when page size !4K
For small objects the kernel's slab implementation is very fast and
space efficient. However, as the allocation size increases to
require multiple pages performance suffers. The SPL kmem cache
allocator was designed to better handle these large allocation
sizes. Therefore, on Linux the kmem_cache_* compatibility wrappers
prefer to use the kernel's slab allocator for small objects and
the custom SPL kmem cache allocator for larger objects.

This logic was effectively disabled for all architectures using
a non-4K page size which caused all kmem caches to only use the
SPL implementation. Functionally this is fine, but the SPL code
which calculates the target number of objects per-slab does not
take in to account that __vmalloc() always returns page-aligned
memory. This can result in a massive amount of wasted space when
allocating tiny objects on a platform using large pages (64k).

To resolve this issue we set the spl_kmem_cache_slab_limit cutoff
to 16K for all architectures. 

This particular change does not attempt to update the logic used
to calculate the optimal number of pages per slab. This remains
an issue which should be addressed in a future change.

A couple of small style cleanups
In `zpool_load_compat()`:

  * initialize `l_features[]` with a loop rather than a static
    initializer.

  * don't redefine system constants; use private names instead

Rationale here:

When an array is initialized using a static {foo}, only the specified
members are initialized to the provided values, the rest are
initialized to zero. While B_FALSE is of course zero, it feels
unsafe to rely on this being true forever, so I'm inclined to sacrifice
a few microseconds of runtime here and initialize using a loop.

When looking for the correct combination of system constants to use
(in open() and mmap()), I prefer to use private constants rather than
redefining system ones; due to the small chance that the system
ones might be referenced later in the file. So rather than defining
O_PATH and MAP_POPULATE, I use distinct constant names.

zfs_arc_overflow_shift was never a parameter:
ca0bf58d65 ("Illumos 5497 - lock
contention on arcs_mtx") is the only result in
git log -Soverflow_shift, and it wasn't exposed then, nor is it now

zfs_read_chunk_size was renamed to zfs_vnops_read_chunk_size in
e53d678d4a ("Share zfs_fsync, zfs_read,
zfs_write, et al between Linux and FreeBSD")

zio_decompress_fail_fraction was never a parameter: it was added in
c3bd3fb4ac ("OpenZFS 9403 - assertion
failed in arc_buf_destroy()") as a developer aid for setting in zdb, but
it's a dangerous test tunable and has no place in public documentation,
(not to mention that it obviously doesn't work):
> Although this did uncover a few low priority issues, this
  unfortuantely also causes ztest to ASSERT in many locations where the
  code is working correctly since it is designed to fail on IO errors.
  Developers can manually set this variable with the '-o' option to find
  and debug issues.
