zfs-jail.8: Add introductory sentence, refactor
Add an introductory sentance explaining why the reader may want to use
this command, and establishing the requirement that the jail must be
running. Move other requirements from the description of the subcommands
to follow this for flow and structure. Move the caveat that this is for
FreeBSD down to a cannonical CAVEATS section, and crossreference Linux's
equivelant functionality. Mention that this utility can not be used to
delegate the root directory of the jail to that section also.

Linux 6.17 compat: Fix broken projectquota on 6.17
We need to specifically use the FX_XFLAG_* macros in zpl_ioctl_*attr()
codepaths, and the FS_*_FL macros in the zpl_ioctl_*flags() codepaths.
The earlier code just assumes the FS_*_FL macros for both codepaths.
The 6.17 kernel add a bitmask check in copy_fsxattr_from_user() that
exposed this error via failing 'projectquota' ZTS tests.

Fix gang write late_arrival bug
When a write comes in via dmu_sync_late_arrival, its txg is equal to the
open TXG. If that write gangs, and we have not yet activated the new
gang header feature, and the gang header we pick can store a larger gang
header, we will try to schedule the upgrade for the open TXG + 1. In
debug mode, this causes an assertion to trip. This PR sets the TXG for
activating the feature to be the larger of either the current open TXG
or the syncing TXG + 1.

Update dnode_next_offset_level to accept blkid instead of offset
Currently this function uses L0 offsets which:
1. is hard to read since it maps offsets to blkid and back each call
2. necessitates dnode_next_block to handle edge cases at limits
3. makes it hard to tell if the traversal can loop infinitely
Instead, update this and dnode_next_offset to work in (blkid, index).
This way the blkid manipulations are clear, and it's also clear that
the traversal always terminates since blkid goes one direction.
I've also considered updating dnode_next_offset to operate on blkid.
Callers use both patterns, so maybe another PR can split the cases?
While here tidy up dnode_next_offset_level comments.

Cleanup ZIO_FLAG_IO_RETRY vs TRYHARD usage
In cases where all issued ZIOs must succeed, and we can't do
anything clever about the errors, we should just explicitly set
ZIO_FLAG_TRYHARD and let OS to do all the reasonable retries.
In other cases, where retries can be different from the original,
for example, some ZIOs are allowed to fail due to redundancy, or
we can disable aggregation on retrial to get at least some of
the data, we can do first pass without TRYHARD, and only if needed
retry with ZIO_FLAG_IO_RETRY (which implies TRYHARD semantics).

Fix caching of DDT log and BRT
Both DDT log and BRT counters we read on pool import and then only
append or overwrite in full blocks. We don't need them in DMU or
ARC caches. Fortunately we have DMU_UNCACHEDIO for this now.
Even more we don't need BRT in non-evictable metadata DMU caches,
since it will likely never fit there, while block the cache from
its original users. Since DMU_OT_IS_METADATA_CACHED() has no way
to differentiate the new metadata types, mark BRT with storage
type of DMU_OT_DDT_ZAP. As side effect it will also put it on
dedup device, but that should actually be right.

ZTS: fail test run if test runner crashes unexpectedly
zfs-tests.sh executes test-runner.py to do the actual test work. Any
exit code < 4 is interpreted as success, with the actual value
describing the outcome of the tests inside.
If a Python program crashes in some way (eg an uncaught exception), the
process exit code is 1.
Taken together, this means that test-runner.py can crash during setup,
but return a "success" error code to zfs-tests.sh, which will report and
exit 0. This in turn causes the CI runner to believe the test run
completed successfully.
This commit addresses this by making zfs-tests.sh interpret an exit code
of 255 as a failure in the runner itself. Then, in test-runner.py, the
"fail()" function defaults to a 255 return, and the main function gets
wrapped in a generic exception handler, which prints it and calls
fail().

FreeBSD: zfs_getpages: Don't zero freshly allocated pages
Initially, `zfs_getpages()` is provided with an array of busy pages by
the vnode pager. It then tries to acquire the range lock, but if there
is a concurrent `zfs_write()` running and fails to acquire that range
lock, it "unbusies" the pages to avoid a deadlock with `zfs_write()`.
After that, it grabs the pages again and retries to acquire the range
lock, and so on.
Once it got the range lock, it filters out valid pages, then copy DMU
data to the remaining invalid pages.
The problem is that freshly allocated zero'd pages it grabbed itself are
marked as valid. Therefore they are skipped by the second part of the
function and DMU data is never copied to these pages. This causes mapped
pages to contain zeros instead of the expected file content.
This was discovered while working on RabbitMQ on FreeBSD. I could
reproduce the problem easily with the following commands:

pool_iter_refresh: don't refresh pools twice
In "all pools" mode, pool_iter_refresh() will call zpool_iter(), which
will call zpool_refresh_stats() before calling add_pool(). If we already
have the pool, this is a different handle, so we just release it and
return. Back in pool_iter_refresh(), we then call zpool_stats_refresh()
again for our handle on the same pool.
All together, this means we're doing two ZFS_IOC_POOL_STATS calls into
the kernel for every pool in the system. This isn't wrong, but it does
double the pressure on global locks.
Instead, we add a new function zpool_refresh_stats_from_handle() that
simply copies the pool config and state from one handle to another, and
use it to update our handle before we release it in add_pool(), so we
only have one call per pool per interval.

This change explicitly passes ZPOOL_CONFIG_ASHIFT to all vdevs,
allowing override for parents only if the passed value is below

zdb: adjust block histogram binning strategy
Previously, a bin included all blocks _starting_ from given size
(e.g., a "4K" bin would include all blocks within the [4K; 8K) region).
This is counter-intuitive and does not match the typical use-case of the
block histogram (that is, to estimate disk usage considering how ZFS'
block allocation works). In other words, if I'm looking at the "4K" row,
I'm interested in records that _fit into_ a 4K block.
Adjust the binning strategy such that a bin includes all blocks _up to_
given size, such that e.g. a "4K" bin would include all blocks within
the (2K; 4K] region.
