powerpc64: Support ELFv2 asm on Big Endian
FreeBSD/powerpc64 is all ELFv2 since FreeBSD 13, even big endian.  The
existing sha256 and sha512 asm code assumes that BE is all ELFv1, and LE
is ELFv2.  Minor changes to add ELFv2 in the BE side gets this working
correctly on FreeBSD with latest OpenZFS import.

Create zap for root vdev
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

libzfs: add v2 iterator interfaces
f6a0dac84 modified the zfs_iter_* functions to take a new "flags"
parameter, and introduced a variety of flags to ask the kernel to limit
the results in various ways, reducing the amount of work the caller
needed to do to filter out things they didn't need.

Unfortunately this change broke the ABI for existing clients (read:
older versions of the `zfs` program), and was reverted 399b98198.

dc95911d2 reintroduced the original patch, with the understanding that a
backwards-compatible fix would be made before the 2.2 release branch was
tagged. This commit is that fix.

This introduces zfs_iter_*_v2 functions that have the new flags
argument, and reverts the existing functions to not have the flags
parameter, as they were before. The old functions are now reimplemented
in terms of the new, with flags set to 0.

d1807f168e nvpair: Constify string functions
After addressing coverity complaints involving `nvpair_name()`, the
compiler started complaining about dropping const. This lead to a rabbit
hole where not only `nvpair_name()` needed to be constified, but also
`nvpair_value_string()`, `fnvpair_value_string()` and a few other static
functions, plus variable pointers throughout the code. The result became
a fairly big change, so it has been split out into its own patch.

discover_cached_paths() will write a NULL into a string from a nvlist to

47a7062772 zpool_valid_proplist() should not corrupt nvpair name string on error
The strings returned from parsing nvlists should be immutable, but to
simplify the code when we want a substring from it, we sometimes will
write a NULL into it and then restore the value afterward. Provided
there is no concurrent access, this is okay, unless we forget to restore
the value afterward. This was caught when constifying string functions
related to nvlists.

zcommon: Refactor FPU state handling in fletcher4
Currently calls to kfpu_begin() and kfpu_end() are split between
the init() and fini() functions of the particular SIMD
implementation. This was done in #14247 as an optimization measure
for the ABD adapter. Unfortunately the split complicates FPU
handling on platforms that use a local FPU state buffer, like
Windows and macOS.

To ease porting, we introduce a boolean struct member in
fletcher_4_ops_t, indicating use of the FPU, and move the FPU state
handling from the SIMD implementations to the call sites.

Better handling for future crypto parameters
The intent is that this is like ENOTSUP, but specifically for when
something can't be done because we have no support for the requested
crypto parameters; eg unlocking a dataset or receiving a stream
encrypted with a suite we don't support.

Its not intended to be recoverable without upgrading ZFS itself.
If the request could be made to work by enabling a feature or modifying
some other configuration item, then some other code should be used.

load-key: In the future we might have more crypto suites (ie new values
for the `encryption` property. Right now trying to load a key on such
a future crypto suite will look up suite parameters off the end of the
crypto table, resulting in misbehaviour and/or crashes (or, with debug
enabled, trip the assertion in `zio_crypt_key_unwrap`).

Instead, lets check the value we got from the dataset, and if we can't
handle it, abort early.

recv: When receiving a raw stream encrypted with an unknown crypto
suite, `zfs recv` would report a generic `invalid backup stream`
(EINVAL). While technically correct, its not super helpful, so lets
ship a more specific error code and message.

Give strlcat() full buffer lengths rather than smaller buffer lengths
strlcat() is supposed to be given the length of the destination buffer,
including the existing contents. Unfortunately, I had been overzealous
when I wrote a51288aabb, since I gave it
the length of the destination buffer, minus the existing contents. This
likely caused a regression on large strings.

On the topic of being overzealous, the use of strlcat() in
dmu_send_estimate_fast() was unnecessary because recv_clone_name is a
fixed length string. We continue using strlcat() mostly as defensive
programming, in case the string length is ever changed, even though it
is unnecessary.

Reject streams that set ->drr_payloadlen to unreasonably large values
In the zstream code, Coverity reported:

"The argument could be controlled by an attacker, who could invoke the
function with arbitrary values (for example, a very high or negative
buffer size)."

It did not report this in the kernel. This is likely because the
userspace code stored this in an int before passing it into the
allocator, while the kernel code stored it in a uint32_t.

However, this did reveal a potentially real problem. On 32-bit systems
and systems with only 4GB of physical memory or less in general, it is
possible to pass a large enough value that the system will hang. Even
worse, on Linux systems, the kernel memory allocator is not able to
support allocations up to the maximum 4GB allocation size that this
allows.

This had already been limited in userspace to 64MB by
`ZFS_SENDRECV_MAX_NVLIST`, but we need a hard limit in the kernel to
protect systems. After some discussion, we settle on 256MB as a hard
upper limit. Attempting to receive a stream that requires more memory
than that will result in E2BIG being returned to user space.

Configure zed's diagnosis engine with vdev properties
Introduce four new vdev properties:
    checksum_n
    checksum_t
    io_n
    io_t

These properties can be used for configuring the thresholds of zed's
diagnosis engine and are interpeted as <N> events in T <seconds>.

When this property is set to a non-default value on a top-level vdev,
those thresholds will also apply to its leaf vdevs. This behavior can be
overridden by explicitly setting the property on the leaf vdev.

Note that, these properties do not persist across vdev replacement. For
this reason, it is advisable to set the property on the top-level vdev
instead of the leaf vdev.

The default values for zed's diagnosis engine (10 events, 600 seconds)
remains unchanged.

deadlock between spa_errlog_lock and dp_config_rwlock
There is a lock order inversion deadlock between `spa_errlog_lock` and
`dp_config_rwlock`:

A thread in `spa_delete_dataset_errlog()` is running from a sync task.
It is holding the `dp_config_rwlock` for writer (see
`dsl_sync_task_sync()`), and waiting for the `spa_errlog_lock`.

A thread in `dsl_pool_config_enter()` is holding the `spa_errlog_lock`
(see `spa_get_errlog_size()`) and waiting for the `dp_config_rwlock` (as
reader).

Note that this was introduced by #12812.

This commit address this by defining the lock ordering to be
dp_config_rwlock first, then spa_errlog_lock / spa_errlist_lock.
spa_get_errlog() and spa_get_errlog_size() can acquire the locks in this
order, and then process_error_block() and get_head_and_birth_txg() can
verify that the dp_config_rwlock is already held.

Additionally, a buffer overrun in `spa_get_errlog()` is corrected.  Many
code paths didn't check if `*count` got to zero, instead continuing to
overwrite past the beginning of the userspace buffer at `uaddr`.

Tested by having some errors in the pool (via `zinject -t data
/path/to/file`), one thread running `zpool iostat 0.001`, and another
thread runs `zfs destroy` (in a loop, although it hits the first time).
This reproduces the problem easily without the fix, and works with the
fix.

Allow receiver to override encryption properties in case of replication
Currently, the receiver fails to override the encryption
property for the plain replicated dataset with the error:
"cannot receive incremental stream: encryption property
'encryption' cannot be set for incremental streams.". The
problem is resolved by allowing the receiver to override
the encryption property for plain replicated send.

zfs list: Allow more fields in ZFS_ITER_SIMPLE mode
If the fields to be listed and sorted by are constrained to those
populated by dsl_dataset_fast_stat(), then zfs list is much faster,
as it does not need to open each objset and reads its properties.

A previous optimization by Pawel Dawidek
(0cee24064a) took advantage
of this to make listing snapshot names sorted only by name much faster.

However, it was limited to `-o name -s name`, this work extends this
optimization to work with:
  - name
  - guid
  - createtxg
  - numclones
  - inconsistent
  - redacted
  - origin
and could be further extended to any other properties supported by
dsl_dataset_fast_stat() or similar, that do not require extra locking
or reading from disk.

This was committed before (9a9e2e343dfa2af28bf7910de77ae73aa006de62),
but was reverted due to a regression when used with an older kernel.

If the kernel does not populate zc->zc_objset_stats, we now fallback
to getting the properties via the slower interface, to avoid problems
with newer userland and older kernels.

5f73bbba43 Do not pass -1 to strerror() from zfs_send_cb_impl()
`zfs_send_cb_impl()` calls `dump_filesystems()`, which calls
`dump_filesystem()`, which will return `-1` as an error when
`zfs_open()` returns `NULL`.

This will be passed to `zfs_standard_error()`, which passes it to
`zfs_standard_error_fmt()`, which passes it to `strerror()`.

To fix this, we modify zfs_open() to set `errno` whenever it returns
NULL. Most of the cases already have `errno` set (since they pass it to
`zfs_standard_error_fmt()`, which makes this easy. Then we modify
`dump_filesystem()` to pass `errno` instead of `-1`.

0a0166c975 FreeBSD: do_mount() passes wrong string length to helper
It should pass `MNT_LINE_MAX`, but passes `sizeof (mntpt)`. This is
harmless because the strlen is not actually used by the helper, but
FreeBSD's Coverity scans complained about it.

This was missed in my audit of various string functions since it is not
actually passed to a string function.

Upon review, it was noticed that the helper function does not need to be
a separate function, so I have inlined it as cleanup.

Allow to control failfast
Linux defaults to setting "failfast" on BIOs, so that the OS will not
retry IOs that fail, and instead report the error to ZFS.

In some cases, such as errors reported by the HBA driver, not
the device itself, we would wish to retry rather than generating
vdev errors in ZFS. This new property allows that.

This introduces a per vdev option to disable the failfast option.
This also introduces a global module parameter to define the failfast
mask value.

Considerable further cleanup is possible including removal of
