Pull all of the internal debug infrastructure up in to the zfs
code to clean up the layering. Remove all the dodgy usage of
SET_ERROR and DTRACE_PROBE from the spl. Luckily it was
lightly used in the spl layer so we're not losing much.

sys/debug.h is not really the right place for them, but we already have
some there for libspl, so it is at least convenient.

Introduce a new vdev property `VDEV_PROP_SLOW_IO_REPORTING` that
allows users to disable notifications for slow devices.
This prevents ZED and/or ZFSD from degrading the pool due to slow

Implement BRT (Block Reference Table) prefetch functionality similar
to existing DDT prefetch. This allows preloading BRT metadata into
ARC to improve performance for block cloning operations and frees
of earlier cloned blocks.
Make -t parameter optional. When omitted, prefetch all supported
metadata types (both DDT and BRT now).

This is useful as debugging support, as it lets namespace lock
operations be traced directly. It will also be useful for future work to
reduce the use of spa_namespace_lock, traditionally a source of
difficult deadlocks.

BRT_RANGESIZE_TO_NBLOCKS() takes number of ranges as its argument.
To get number of blocks we should multiply it by the entry size,
not divide by it, as it was due to missing parentheses.
Before #17875 this could cause small memory corruptions for vdevs
bigger than 64TB, but the change made the bug more noticeable.

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.

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.

Over the time many of DMU functions got flags argument to control
prefetch, caching, etc. Few functions though left without it, even
though closer look shown that many of them do not require prefetch
due to their access pattern. This patch adds the flags argument to
dmu_write(), dmu_buf_hold_array() and dmu_buf_hold_array_by_bonus(),
passing DMU_READ_NO_PREFETCH where applicable.
I am going to also pass DMU_UNCACHEDIO to some of them later.

Provide an interface to retrieve the lowest and highest minimum
allocation size for the normal allocation class. This can be used
by external consumers of the DMU to estimate potential wasted
capacity when setting the recordsize for an object.
The new "min_alloc" and "max_alloc" keys are added to the pool
configuration and used by default_volblocksize() to warn when
an ineffecient block size is requested. For older kmods which
don't yet include the new keys fallback to the previous logic.

A single slow responding disk can affect the overall read
performance of a raidz group. When a raidz child disk is
determined to be a persistent slow outlier, then have it
sit out during reads for a period of time. The raidz group
can use parity to reconstruct the data that was skipped.
Each time a slow disk is placed into a sit out period, its
`vdev_stat.vs_slow_ios count` is incremented and a zevent
class `ereport.fs.zfs.delay` is posted.
The length of the sit out period can be changed using the
`raid_read_sit_out_secs` module parameter. Setting it to
zero disables slow outlier detection.
