For zpool import and zpool split, zpool_enable_datasets is called
to mount and share all datasets in a pool. If there is an error
while mounting or sharing any dataset in the pool, the status of
import or split is reported as failure. However, the changes do
show up in zpool list.
This commit updates the error reporting in zpool import and zpool
split path. More descriptive messages are shown to user in case
there is an error during mount or share. Errors in mount or share
do not effect the overall status of zpool import and zpool split.

When the vdev properties features was merged an extra check
was added in `spa_vdev_remove_top_check()` which checked
whether the vdev that we want to remove is already being
removed and if so return an EALREADY error.
```
static int
spa_vdev_remove_top_check(vdev_t *vd)
{
... <snip> ...
/*
* This device is already being removed
*/
if (vd->vdev_removing)
return (SET_ERROR(EALREADY));
```
Before that change we'd still fail with an error but it
was a more generic one - here is the check that failed
later in the same function:
```
/*
* There can not be a removal in progress.
*/
if (spa->spa_removing_phys.sr_state == DSS_SCANNING)
return (SET_ERROR(EBUSY));
```
Changing the error code returned from that function changed
the behavior of the removal's library interface exposed to
the userland - `spa_vdev_remove()` now returns `EZFS_UNKNOWN`
instead of `EZFS_EBUSY` that was returning before.
This patch adds logic to make `spa_vdev_remove()` mindful
of the new EALREADY code and propagating `EZFS_EBUSY`
reverting to the previously established semantics of that
function.

It was a vdev level read cache, designed to aggregate many small
reads by speculatively issuing bigger reads instead and caching
the result. But since it has almost no idea about what is going
on with exception of ZIO_FLAG_DONT_CACHE flag set by higher layers,
it was found to make more harm than good, for which reason it was
disabled for the past 12 years. These days we have much better
instruments to enlarge the I/Os, such as speculative and prescient
prefetches, I/O scheduler, I/O aggregation etc.
Besides just the dead code removal this removes one extra mutex

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

f6a0dac84 modified the zfs_iter_* functions to take a new "flags"
parameter, and introduced a variety of flags to ask the kernel to limit

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

load-key: In the future we might have more crypto suites (ie new values

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

On the topic of being overzealous, the use of strlcat() in

fixed length string. We continue using strlcat() mostly as defensive

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.

Note that, these properties do not persist across vdev replacement. For

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

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

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.

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.

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 (9a9e2e343d),
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.

`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`.
