On compression we could be more explicit here for cases

ZLE compressor needs additional bytes to process
d_len argument efficiently.
Don't use BPE_PAYLOAD_SIZE as d_len with it
before we rework zle compressor somehow.

Closes#9416
Now default compression is lz4, which can stop
compression process by itself on incompressible data.
If there are additional size checks -
we will only make our compressratio worse.
New usable compression thresholds are:
- less than BPE_PAYLOAD_SIZE (embedded_data feature);
- at least one saved sector.
Old 12.5% threshold is left to minimize affect
on existing user expectations of CPU utilization.
If data wasn't compressed - it will be saved as
ZIO_COMPRESS_OFF, so if we really need to recompress
data without ashift info and check anything -
we can just compress it with zero threshold.
So, we don't need a new feature flag here!

I think cli_root/zdb/zdb_backup.ksh runs also an FreeBSD and I needed to
include the sysutils/coreutils package for the FreeBSD tests within the
QEMU patchset.
This could be reverted, when this pull request gets upstream

For now, userspace has no znode implementation. Some of the property and
path handling code is used there though and is the same on all
platforms, so we only need a single copy of it.

The Linux arc_os.c carries userspace and kernel code, with very little
overlap between the two. This lifts the userspace parts out into a
separate arc_os.c for libzpool and removes it from the Linux side.

All kernels we support have compound pages that work the way we would
like. However, this code is new and this knowledge was hard won, so I'd
like to leave the description and option there for a little while, even
if it can only be disabled with a recompile.

Specializing cityhash4 on 32-bit architectures can reduce the size
of stack frames as well as instruction count. This is a tiny but
useful optimization, since some callers invoke it frequently.
When specializing into 1/2/3/4-arg versions, the stack usage
(in bytes) on some 32-bit arches are listed as follows:
- x86: 32, 32, 32, 40
- arm-v7a: 20, 20, 28, 36
- riscv: 0, 0, 0, 16
- power: 16, 16, 16, 32
- mipsel: 8, 8, 8, 24
And each actual argument (even if passing 0) contributes evenly
to the number of multiplication instructions generated:
- x86: 9, 12, 15 ,18
- arm-v7a: 6, 8, 10, 12
- riscv / power: 12, 18, 20, 24
- mipsel: 9, 12, 15, 19
On 64-bit architectures, the tendencies are similar. But both stack
sizes and instruction counts are significantly smaller thus negligible.

As mentioned in PR #16131, replacing CRC-based hash with cityhash4
could slightly improve the performance by eliminating memory access.
Replacing algorightm is safe since the hash result is not persisted.

FreeBSD 14 gained a `VOP_DEALLOCATE` VFS operation and a `fspacectl`
syscall to use it. At minimum, these zero the given region, and if the
underlying filesystem supports it, can make the region sparse. We can
use this to get TRIM-like behaviour for file vdevs.

We only use it on a specific way: to punch a hole in (make sparse) a
region of a file, in order to implement TRIM-like behaviour.
So, call the op "deallocate", and move the Linux-style mode flags down
into the Linux implementation, since they're an implementation detail.
FreeBSD gets a no-op stub (for the moment).
