Currently, when reading compressed blocks with -R and decompressing
them with :d option and specifying lsize, which is normally bigger
than psize for compressed blocks, the checksum is calculated on
decompressed data. But it makes no sense since zfs always calculates
checksum on physical, i.e. compressed data. So reading the same block
produces different checksum results depending on how we read it,
whether we decompress it or not, which, again, makes no sense.
Fix: use psize instead of lsize when calculating the checksum so that
it is always calculated on the physical block size, no matter was it
compressed or not.

During hotplug REMOVED events, devid matching fails for partition-based
spares because devid information is not stored in pool config for
partitioned devices. However, when devid is populated by the hotplug
event, the original code skipped the search logic entirely, skipping
vdev_guid matching and resulting in wrong device type detection that
caused spares to be incorrectly identified as l2arc devices.
Additionally, fix zfs_agent_iter_pool() to use the return value from
zfs_agent_iter_vdev() instead of relying on search parameters, which
was previously ignored. Also add pool_guid optimization to enable
targeted pool searching when pool_guid is available.

Before this change ZIL blocks were allocated only from normal or
SLOG vdevs. In typical situation when special vdevs are SSDs and
normal are HDDs it could cause weird inversions when data blocks
are written to SSDs, but ZIL referencing them to HDDs.
This change assumes that special vdevs typically have much better
(or at least not worse) latency than normal, and so in absence of
SLOGs should store ZIL blocks. It means similar to normal vdevs
introduction of special embedded log allocation class and updating
the allocation fallback order to: SLOG -> special embedded log ->
special -> normal embedded log -> normal.
The code tries to guess whether data block is going to be written
to normal or special vdev (it can not be done precisely before
compression) and prefer indirect writes for blocks written to a
special vdev to avoid double-write. For blocks that are going to
be written to normal vdev, special vdev by default plays as SLOG,
reducing write latency by the cost of higher special vdev wear,
but it is tunable via module parameter.
This should allow HDD pools with decent SSD as special vdev to
work under synchronous workloads without requiring additional
SLOG SSD, impractical in many scenarios.

Special vdevs were originally designed as a small blocks storage
for dRAID, for which role RAIDZ/dRAID topologies are not good.
But it is more often used as SSD storage for metadata and hot
data of HDD pools. In these use cases narrow RAIDZ of SSDs might
be fine, so we should not introduce unnecessary restrictions,
and ZFS internally does not care.
Similar applies to dedup vdevs. Original DDT used 4KB blocks,
for which anything but mirror was a terrible storage. But new
FDT implementation uses 32KB blocks by default, which are much
less demanding even including compression, and which could be
increased even higher now, if needed.

Before Direct I/O was implemented, I've implemented lighter version
I called Uncached I/O. It uses normal DMU/ARC data path with some
optimizations, but evicts data from caches as soon as possible and
reasonable. Originally I wired it only to a primarycache property,
but now completing the integration all the way up to the VFS.
While Direct I/O has the lowest possible memory bandwidth usage,
it also has a significant number of limitations. It require I/Os
to be page aligned, does not allow speculative prefetch, etc. The
Uncached I/O does not have those limitations, but instead require
additional memory copy, though still one less than regular cached
I/O. As such it should fill the gap in between. Considering this
I've disabled annoying EINVAL errors on misaligned requests, adding
a tunable for those who wants to test their applications.
To pass the information between the layers I had to change a number
of APIs. But as side effect upper layers can now control not only
the caching, but also speculative prefetch. I haven't wired it to
VFS yet, since it require looking on some OS specifics. But while
there I've implemented speculative prefetch of indirect blocks for
Direct I/O, controllable via all the same mechanisms.

The redundant_metadata setting in ZFS allows users to trade resilience
for performance and space savings. This applies to all data and metadata
blocks in zfs, with one exception: gang blocks. Gang blocks currently
just take the copies property of the IO being ganged and, if it's 1,
sets it to 2. This means that we always make at least two copies of a
gang header, which is good for resilience. However, if the users care
more about performance than resilience, their gang blocks will be even
more of a penalty than usual.
We add logic to calculate the number of gang headers copies directly,
and store it as a separate IO property. This is stored in the IO
properties and not calculated when we decide to gang because by that
point we may not have easy access to the relevant information about what
kind of block is being stored. We also check the redundant_metadata
property when doing so, and use that to decide whether to store an extra
copy of the gang headers, compared to the underlying blocks.

- Use ZIO_PRIORITY_REMOVAL for early stages of expansion, same as
for main ones.
- Fix rate overflows in `zpool status` reporting.
With these changes expanding RAIDZ1 from 4 to 5 children I am able
to reach 6-12GB/s rate on SSDs and ~500MB/s on HDDs, both are
limited by devices instead of CPU.

In 6f50f8e16 we added flex arrays to lr_XX_t structs to silence kernel
bounds check warnings. Userspace code was mostly not updated to use them
though.
It seems that in the right circumstances, compilers can get confused
about sizes in the same way, and throw warnings. This commits switch
those uses over to use the flex array fields also.

In some cases like dsl_dataset_hold_obj() it is possible to handle
those errors, so failure to hold dataset should be better than
kernel panic. Some other places where these errors are still not
handled but asserted should be less dangerous just as unreachable.
We have a user report about pool corruption leading to assertions
on these errors. Hopefully this will make behavior a bit nicer.
