u8_textprep: move into module/zfs
Now that it's built into the main zfs module in all cases, there's no
reason to put it in its own dir.

The qemu-test-repo-vm.sh script tests installs ZFS from different
repos. Have it test from the new 2.4.x repos as well.
Also add a checkbox to run in "lookup mode". This just does a
quick lookup to see what version is installed in each repo. It does
not do a test install and module load. It only takes 3min to run vs
over an hour for the full version.

Fix interaction of abd_iter_map()/abd_iter_unmap() with HIGHMEM
HIGHMEM kmap interfaces operate on only a single page at a time
yet ZFS hadn't accounted for this, resulting in crashes and
potential memory corruption on HIGHMEM (typically 32-bit) systems.
This was caught by PaX's KERNSEAL feature as it makes use of
HIGHMEM functionality on x64.
On typical 64-bit systems, this issue wouldn't have been observed,
as the map interfaces simply fall back to returning an address in
lowmem where the contiguous pages can be accessed directly.

ZIO: Set minimum number of free issue threads to 32
Free issue threads might block waiting for synchronous DDT, BRT or
GANG header reads. So unlike other taskqs using ZTI_SCALE to scale
with number of CPUs, here we also need some amount of threads to
potentially saturate pool reads. I am not sure we always want the
96 threads we had before ZTI_SCALE introduction at #11966 on small
systems, but lets make it at least 32.
While here, make free taskqs configurable, similar to read and
write ones.

We do this so that we can always build packages from a branch, even if

Explicit set ashift for non-leaf vdevs
Before this change ashift property was applied only to a leaf
vdevs. As result, it worked only as a minimal value for parent
vdevs, since bigger physical_ashift value reported by any child
could be used instead when deciding parent's ashift, as if the
ashift property was never set.
This change explicitly passes ZPOOL_CONFIG_ASHIFT to all vdevs,
allowing override for parents only if the passed value is below
logical_ashift and so unacceptable.

Fix rangelock test for growing block size
If the file already has more than one block, then the current
block size cannot change. But if the file block size is less
than the maximum block size supported by the file system, and
there are multiple blocks in the file, the current code will
almost always extend the rangelock to its maximum size.
This means that all writes become serialized and even reads
are slowed as they will more often contend with writes. This
commit adjusts the test so that we will not lock the entire
range if there is more than one block in the file already.
