The memcpy(), memmove(), and memset() functions have been annotated
to perform bounds checking when using FORTIFY_SOURCE. A warning is
now generted when writing beyond the end of the specified field.
Alternately, the new struct_group() macro could be used to create
an anonymous union member for use by memcpy(). However, since this
is the only place the macro would be helpful it's preferable to
restructure the code slights to avoid the need for additional
compatibility code when the macro does not exist.

The current codebase does not support raw sending buffers with block
size > 128kB when large_blocks is not active. This can happen in the
codepath dsl_dataset_sync()->dmu_objset_sync()->zio_nowait() which
calls back dmu_objset_write_done()->dsl_dataset_block_born(). If
dsl_dataset_sync() completes its run before dsl_dataset_block_born() is
called, we will end up not activating some of the necessary flags, while
having blocks based on those flags written in the filesystem. A
subsequent send will then panic.
Fix this by directly deciding in dmu_objset_sync() whether these flags
need to be activated later by dsl_dataset_sync(). Instead of panicking
due to a NULL pointer dereference in dmu_dump_write() in case of a send,
print out an error message. Also during scrub verify there are no
contradicting filesystem flags.

- Introduce first element offset within a leaf. It allows to reduce
by ~50% average memmove() size when adding/removing elements. If the
added/removed element is in the first half of the leaf, we may shift
elements before it and adjust the bth_first instead of moving more
elements after it.
- Use memcpy() instead of memmove() when we know there is no overlap.
- Switch from uint64_t to uint32_t. It does not limit anything,
but 32-bit arches should appreciate it greatly in hot paths.
- Store leaf capacity in struct btree to avoid 64-bit divisions.
- Adjust zfs_btree_insert_into_leaf() to always result in balanced
leaves after splitting, no matter where the new element was inserted.
Not that we care about it much, but it should also allow B-trees with
as little as two elements per leaf instead of 4 previously.
When scrubbing pool of 12 SSDs, storing 1.5TB of 4KB zvol blocks this
reduces amount of time spent in memmove() inside the scan thread from
13.7% to 5.7% and total scrub time by ~15 seconds out of 9 minutes.
It should also reduce spacemaps load time, but I haven't measured it.

Workaround for #12762Closes#13256
- Reduce size and comparison complexity of q_exts_by_size B-tree.
Previous code used two 64-bit divisions and many other operations to
compare two B-tree elements. It created enormous overhead. This
implementation moves the math to the upper level and stores the score
in the B-tree elements themselves. Since all that we need to store in
that B-tree is the extent score and offset, those can fit into single
8 byte value instead of 24 bytes of q_exts_by_addr element and can be
compared with single operation.
- Better decouple secondary tree logic from main range_tree by moving
rt_btree_ops and related functions into dsl_scan.c as ext_size_ops.
Those functions are very small to worry about the code duplication and
range_tree does not need to know details such as rt_btree_compare.
- Instead of accounting number of pending bytes per pool, that needs
atomic on global variable per block, account the number of non-empty
per-vdev queues, that change much more rarely.
- When extent scan is interrupted by TXG end, continue it in the next
TXG instead of selecting next best extent. It allows to avoid leaving
one truncated (and so likely not the best any more) extent each TXG.
On top of some other optimizations this saves about 1.5 minutes out of
10 to scrub pool of 12 SSDs, storing 1.5TB of 4KB zvol blocks.

When scrubbing a raidz/draid pool, which contains a replacing or
sparing mirror with multiple online children, only one child will
be read. This is not normally a serious concern because the DTL
records are used to determine where a good copy of the data is.
As long as the data can be read from one child the mirror vdev
will use it to repair gaps in any of its children. Furthermore,
even if the data which was read is corrupt the raidz code will
detect this and issue its own repair I/O to correct the damage
in the mirror vdev.
However, in the scenario where the DTL is wrong due to silent
data corruption (say due to overwriting one child) and the scrub
happens to read from a child with good data, then the other damaged
mirror child will not be detected nor repaired.
While this is possible for both raidz and draid vdevs, it's most
pronounced when using draid. This is because by default the zed
will sequentially rebuild a draid pool to a distributed spare,
and the distributed spare half of the mirror is always preferred
since it delivers better performance. This means the damaged
half of the mirror will go undetected even after scrubbing.
For system administrations this behavior is non-intuitive and in
a worst case scenario could result in the only good copy of the
data being unknowingly detached from the mirror.
This change resolves the issue by reading all replacing/sparing
mirror children when scrubbing. When the BP isn't available for
verification, then compare the data buffers from each child. They
must all be identical, if not there's silent damage and an error
is returned to prompt the top-level vdev to issue a repair I/O to
rewrite the data on all of the mirror children. Since we can't
tell which child was wrong a checksum error is logged against the
replacing or sparing mirror vdev.

When building modules (as well as the kernel) with ARCH=um, the options
-Dsetjmp=kernel_setjmp and -Dlongjmp=kernel_longjmp are passed to the C
preprocessor for C files. This causes the setjmp and longjmp used in
module/lua/ldo.c to be kernel_setjmp and kernel_longjmp respectively in
the object file. However, the setjmp and longjmp that is intended to be
called is defined in an architecture dependent assembly file under the
directory module/lua/setjmp. Since it is an assembly and not a C file,
the preprocessor define is not given and the names do not change. This
becomes an issue when modpost is trying to create the Module.symvers
and sees no defined symbol for kernel_setjmp and kernel_longjmp. To fix
this, if the macro CONFIG_UML is defined, then setjmp and longjmp
macros are undefined.
When building with ARCH=um for x86 sub-architectures, CONFIG_X86 is not
defined. Instead, CONFIG_UML_X86 is defined. Despite this, the UML x86
sub-architecture can use the same object files as the x86 architectures
because the x86 sub-architecture UML kernel is running with the same
instruction set as CONFIG_X86. So the modules/Kbuild build file is
updated to add the same object files that CONFIG_X86 would add when
CONFIG_UML_X86 is defined.

improve zvol performance with multithreaded reads/writes.
This implementation uses the blk-mq interfaces on 4.13 or newer
kernels. Building against older kernels will fall back to the
older BIO interfaces.
Note that you must set the `zvol_use_blk_mq` module param to
enable the blk-mq API. It is disabled by default.
In addition, this commit lets the zvol blk-mq layer process whole
`struct request` IOs at a time, rather than breaking them down
into their individual BIOs. This reduces dbuf lock contention
and overhead versus the legacy zvol submit_bio() codepath.

Homepage of BLAKE3: https://github.com/BLAKE3-team/BLAKE3
Wikipedia: https://en.wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE3
Short description of Wikipedia:
BLAKE3 is a cryptographic hash function based on Bao and BLAKE2,
created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and
Zooko Wilcox-O'Hearn. It was announced on January 9, 2020, at Real
World Crypto. BLAKE3 is a single algorithm with many desirable
features (parallelism, XOF, KDF, PRF and MAC), in contrast to BLAKE
and BLAKE2, which are algorithm families with multiple variants.
BLAKE3 has a binary tree structure, so it supports a practically
unlimited degree of parallelism (both SIMD and multithreading) given
enough input. The official Rust and C implementations are
dual-licensed as public domain (CC0) and the Apache License.
Along with adding the BLAKE3 hash into the OpenZFS infrastructure a
new benchmarking file called chksum_bench was introduced. When read
it reports the speed of the available checksum functions.
On Linux: cat /proc/spl/kstat/zfs/chksum_bench
On FreeBSD: sysctl kstat.zfs.misc.chksum_bench

Structurally, the new code is mainly split into these parts:
- 1x cross platform generic c variant: blake3_generic.c
- 4x assembly for X86-64 (SSE2, SSE4.1, AVX2, AVX512)
- 2x assembly for ARMv8 (NEON converted from SSE2)
- 2x assembly for PPC64-LE (POWER8 converted from SSE2)
- one file for switching between the implementations
Note the PPC64 assembly requires the VSX instruction set and the
kfpu_begin() / kfpu_end() calls on PowerPC were updated accordingly.

It is typical, but not generally true that if log summary has more
blocks it must also have unflushed metaslabs. Normally with metaslabs
flushed in order it works, but there are known exceptions, such as
device removal or metaslab being loaded during its flush attempt.
Before 600a02b884 if spa_flush_metaslabs() hit loading metaslab it
usually stopped (unless memlimit is also exceeded), but now it may
flush more metaslabs, just skipping that particular one. This
increased chances of assertion to fire when the skipped metaslab is
flushed on next iteration if all other metaslabs in that summary
entry are already flushed out of order.

As of the Linux 5.19 kernel an identically named zap_flags_t typedef
is declared in the include/linux/mm_types.h linux header. Sadly,
the inclusion of this header cannot be easily avoided. To resolve
the conflict a #define is used to remap the name in the OpenZFS
sources when building against the Linux kernel.

In current zil_commit() process, transaction lwb_tx is assigned in
zil_lwb_write_issue(), and is committed in zil_lwb_flush_vdevs_done().
Thus, during lwb write out process, the txg is held in open or quiesing
state, until zil_lwb_flush_vdevs_done() is called. If the zil's zio
latency is high, it will cause txg_sync_thread() to starve.
The goal here is to defer waiting for zil_lwb_flush_vdevs_done to the
'syncing' txg state. That is, in zil_sync().
In this patch, it achieves the goal without holding transaction.
A new function zil_lwb_flush_wait_all() is introduced. It waits for
the completion of all the zil_lwb_flush_vdevs_done() by given txg.

The EXTRA_DIST variable is ignored when used in the FALSE conditional
of a Makefile.am. This results in the `make dist` target omitting
these files from the generated tarball unless CONFIG_USER is defined.
This issue can be avoided by switching to use the dist_noinst_DATA
variable which is handled as expected by autoconf.
This change also adds support for --with-config=dist as an alias
for --with-config=srpm and updates the GitHub workflows to use it.
