When processing abds, we execute 1 `kfpu_begin()`/`kfpu_end()` pair on
every page in the abd. This is wasteful and slows down checksum
performance versus what the benchmark claimed. We correct this by moving
those calls to the init and fini functions.
Also, we always check the buffer length against 0 before calling the
non-scalar checksum functions. This means that we do not need to execute
the loop condition for the first loop iteration. That allows us to
micro-optimize the checksum calculations by switching to do-while loops.
Note that we do not apply that micro-optimization to the scalar
implementation because there is no check in
`fletcher_4_incremental_native()`/`fletcher_4_incremental_byteswap()`
against 0 sized buffers being passed.

I read the following article and noticed a couple of ZFS bugs mentioned:
https://pvs-studio.com/en/blog/posts/cpp/0377/
I decided to search for them in the modern OpenZFS codebase and then
found one that matched the description of the first one:
V593 Consider reviewing the expression of the 'A = B != C' kind. The
expression is calculated as following: 'A = (B != C)'. zfs_vfsops.c 498
The consequence of this is that the error value is replaced with `1`
when there is an error. When there is no error, 0 is correctly passed.
This is a very minor issue that is unlikely to cause any real problems.
The incorrect error code would either be returned to the mount command
on a failure or any of `zfs receive`, `zfs recv`, `zfs rollback` or `zfs
upgrade`.
The second one has already been fixed.

When doing a device removal on a pool with gang blocks, the zio pipeline
can deadlock when trying to free blocks from a device which is being
removed with a stack similar to this:
0xffff8ab9a13a1740 UNINTERRUPTIBLE 4
__schedule+0x2e5
__schedule+0x2e5
schedule+0x33
schedule_preempt_disabled+0xe
__mutex_lock.isra.12+0x2a7

zio_execute+0x94
zio_execute+0x94
taskq_thread+0x23b
kthread+0x120
ret_from_fork+0x1f
Since there are gang blocks we have to read the gang members as part of
the free. This can be seen with a zio dependency tree that looks like
this:
sdb> echo 0xffff900c24f8a700 | zio -rc | zio
ADDRESS TYPE STAGE WAITER
0xffff900c24f8a700 NULL CHECKSUM_VERIFY 0xffff900ddfd31740
0xffff900c24f8c920 FREE GANG_ASSEMBLE -
0xffff900d93d435a0 READ DONE
In the illustration above we are processing frees but because of gang
block we have to read the constituents blocks. Once we finish the READ
in the zio pipeline we will execute the parent. In this case the parent
is a FREE but the zio taskq is a READ and we continue to process the
pipeline leading to the stack above. In the stack above, we are blocked
waiting for the svr_lock so as a result a READ interrupt taskq thread
is now consumed. Eventually, all of the READ taskq threads end up
blocked and we're unable to complete any read requests.
In zio_notify_parent there is an optimization to continue to use
the taskq thread to exectue the parent's pipeline. To resolve the
deadlock above, we only allow this optimization if the parent's
zio type matches the child which just completed.

Following facebook/zstd#2545, I noticed that one field in `seq_t` is
optional, and only used in combination with prefetching. (This may have
contributed to static analyzer failure to detect correct
initialization).
I then wondered if it would be possible to rewrite the code so that this
optional part is handled directly by the prefetching code rather than
delegated as an option into `ZSTD_decodeSequence()`.
This resulted into this refactoring exercise where the prefetching
responsibility is better isolated into its own function and
`ZSTD_decodeSequence()` is streamlined to contain strictly Sequence
decoding operations. Incidently, due to better code locality, it
reduces the need to send information around, leading to simplified
interface, and smaller state structures.

These `sprintf()` calls are used repeatedly to write to a buffer. There
is no protection against overflow other than reviewers explicitly
checking to see if the buffers are big enough. However, such issues are
easily missed during review and when they are missed, we would rather
stop printing rather than have a buffer overflow, so we convert these
functions to use `kmem_scnprintf()`. The Linux kernel provides an entire
page for module parameters, so we are safe to write up to PAGE_SIZE.
Removing `sprintf()` from these functions removes the last instances of
`sprintf()` usage in our platform-independent kernel code. This improves
XNU kernel compatibility because the XNU kernel does not support
(removed support for?) `sprintf()`.

In #13709, as in #11294 before it, it turns out that 63a26454 still had
the same failure mode as when it was first landed as d1d47691, and
fails to unlock certain datasets that formerly worked.
Rather than reverting it again, let's add handling to just throw out
the accounting metadata that failed to unlock when that happens, as
well as a test with a pre-broken pool image to ensure that we never get
bitten by this again.
Fixes: #13709

The original ARC paper called for an initial 50/50 MRU/MFU split
and this is accounted in various places where arc_p = arc_c >> 1,
with further adjustment based on ghost lists size/hit. However, in
current code both arc_adapt() and arc_get_data_impl() aggressively
grow arc_p until arc_c is reached, causing unneeded pressure on
MFU and greatly reducing its scan-resistance until ghost list
adjustments kick in.
This patch restores the original behavior of initially having arc_p
as 1/2 of total ARC, without preventing MRU to use up to 100% total
ARC when MFU is empty.
