The dmu_buf_is_dirty() call doesn't make sense here for two reasons:
1. txg is 0 for unassigned tx, so it was a no-op.

I don't know an easy way to shrink down dbuf size, so just deny block cloning
into dbufs that don't match our BP's size.
This fixes the following situation:
1. Create a small file, eg. 1kB of random bytes. Its dbuf will be 1kB.
2. Create a larger file, eg. 2kB of random bytes. Its dbuf will be 2kB.
3. Truncate the large file to 0. Its dbuf will remain 2kB.
4. Clone the small file into the large file. Small file's BP lsize is
1kB, but the large file's dbuf is 2kB.

If a block pointer is corrupted (but the block containing it checksums
correctly, e.g. due to a bug that overwrites random memory), we can
often detect it before the block is read, with the `zfs_blkptr_verify()`
function, which is used in `arc_read()`, `zio_free()`, etc.
However, such corruption is not typically recoverable. To recover from
it we would need to detect the memory error before the block pointer is
written to disk.
This PR verifies BP's that are contained in indirect blocks and dnodes
before they are written to disk, in `dbuf_write_ready()`. This way,
we'll get a panic before the on-disk data is corrupted. This will help
us to diagnose what's causing the corruption, as well as being much
easier to recover from.
To minimize performance impact, only checks that can be done without
holding the spa_config_lock are performed.
Additionally, when corruption is detected, the raw words of the block
pointer are logged. (Note that `dprintf_bp()` is a no-op by default,
but if enabled it is not safe to use with invalid block pointers.)

Currently when layering the ABD buffer of each split block on top of
an indirect vdev's ZIO ABD we don't specify the split block's ABD.
This results in those ABDs being incorrectly sized by inheriting
the size of their parent ABD which is larger than what each split
block needs.
The above behavior isn't causing any bugs currently but can lead
to unexpected ABD sizes for people analyzing and/or working on
the ZIO codepath. This patch fixes this behavior by properly setting
the ABD size for split block ZIOs.

API contract requires VOPs to handle EXDEV internally, worst case by
falling back to the generic copy routine. This broke with the recent
changes.
While here whack custom loop to lock 2 vnodes with vn_lock_pair, which
provides the same functionality internally. write start/finish around
it plays no role so got eliminated.
One difference is that vn_lock_pair always takes an exclusive lock on
both vnodes. I did not patch around it because current code takes an
exclusive lock on the target vnode. zfs supports shared-locking for
writes, so this serializes different calls to the routine as is, despite
range locking inside. At the same time you may notice the source vnode
can get some traffic if only shared-locked, thus once more this goes
the safer route of exclusive-locking. Note this should be patched to
use shared-locking for both once the feature is considered stable.
Technically the switch to vn_lock_pair should be a separate change, but
it would only introduce churn immediately whacked by the rest of the
patch.

And add it to the AVZ, this is not backwards compatible with older pools
due to an assertion in spa_sync() that verifies the number of ZAPs of
all vdevs matches the number of ZAPs in the AVZ.
Granted, the assertion only applies to #DEBUG builds - still, a feature
flag is introduced to avoid the assertion, com.klarasystems:vdev_zaps_v2
Notably, this allows to get/set properties on the root vdev:
% zpool set user:prop=value <pool> root-0
Before this commit, it was already possible to get/set properties on
top-level vdevs with the syntax <type>-<vdev_id> (e.g. mirror-0):
% zpool set user:prop=value <pool> mirror-0
This syntax also applies to the root vdev as it is is of type 'root'
with a vdev_id of 0, root-0. The keyword 'root' as an alias for
'root-0'.
The following tests have been added:
- zpool get all properties from root vdev
- zpool set a property on root vdev
- verify root vdev ZAP is created

Linux kernel 6.3 changed a bunch of APIs to use the dedicated idmap
type for mounts (struct mnt_idmap), we need to detect these changes
and make zfs work with the new APIs.

Closes#14682
sha256-armv8.S and sha512-armv8.S need the same treatment as the sse
bits; removal of -mgeneral-regs-only from flags.
This fixes errors about requiring NEON, which is a difference in clang
vs. gcc treatment of -mgeneral-regs-only being specified on asm files.

Add missing machine/md_var.h to spl/sys/simd_aarch64.h and
spl/sys/simd_arm.h
In spl/sys/simd_x86.h, PCB_FPUNOSAVE exists only on amd64, use PCB_NPXNOSAVE
on i386
In FreeBSD sys/elf_common.h redefines AT_UID and AT_GID on FreeBSD, we need
a hack in vnode.h similar to Linux. sys/simd.h needs to be included early.
In zfs_freebsd_copy_file_range() we pass a (size_t *)lenp to
zfs_clone_range() that expects a (uint64_t *)
Allow compiling armv6 world by limiting ARM macros in sha256_impl.c and
sha512_impl.c to __ARM_ARCH > 6

It may happen that "wanted total ARC size" (wt) is negative, that was
expected. But multiplication product of it and unsigned fractions
result in unsigned value, incorrectly shifted right with a sing loss.
