Alan Somers 6fd87e1d8d Don't emit cksum_{actual_expected} in ereport.fs.zfs.checksum events
With anything but fletcher-4, even a tiny change in the input will cause
the checksum value to change completely.  So knowing the actual and
expected checksums doesn't provide much more information than "they
don't match".  The harm in sending them is simply that they bloat the
event.  In particular, on FreeBSD the event must fit into a 1016 byte
buffer.

Fixes #14717 for mirrored pools.

Alan Somers cf2a225b24 Don't emit checksum histograms in ereport.fs.zfs.checksum events
The checksum histograms were intended to be used with ATA and parallel
SCSI, which are obsolete.  With modern storage hardware, they will
almost always look like white noise; all bits will be wrong.  They only
serve to bloat the event.  That's a particular problem on FreeBSD, where
events must fit into a 1016 byte buffer.

This fixes issue #14717 for RAIDZ pools, but not for mirror pools.

Finally drop long disabled vdev cache.
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
lock/unlock per write inside vdev_cache_write(), not otherwise
disabled and trying to do some work.

Properly format NAME subsection of zfs/zpool subcommands
Use proper names (i.e. zfs-allow and zpool-add) in NAME subsections
of zfs/zpool subcommands instead of current "pretty-printed" ones as
makewhatis utilities (or some implementations of it, namely the one
from mandoc suite used in FreeBSD) look not only at the document title
but also in NAME subsection, adding zfs(8)/zpool(8) to search results
which is not correct. (Common sense and other utilities splitting
subcommands in multiple man pages, e.g. git, do the same.)

Remove hard coded "Linux" OS from manpages
The recommended practice for `.Os` on FreeBSD is to not specify any
arguments.  The correct OS name is used automatically.

Oddly enough, on the Linux distro I tested this on (CentOS 7), the man
pager defaulted to displaying "BSD" as the OS rather than "Linux".  To
accommodate this, tack " Linux" back on in an install hook on Linux.
This is much simpler than removing it for FreeBSD when vendored in the
base system.

Ross Williams c5ebfbbe19 Reorganize zpool(8) man page into sections
Moved subcommand topics into individual manpages. Reordered and 
grouped the list of subcommands by topic.

Moved concepts overview to `zpoolconcepts.8` and the long list of
available pool properties to `zpoolprops.8`.

Internal cross-references copied from `zpool.8` needed to be 
converted to `.Xr` external references to new subcommand manual 
pages.

Move `autotrim` into lexical order, autotrim tacked onto the end
of a list. Now it is in alphabetical order.

Clarify attach/detach description. Description was too specific to
command syntax. Overview clarifies reason for attaching or detaching
a device.

Clarify replace description, don't refer to subcommand arguments.

Clarify split command description, say what split actually does and
why you'd want to do it.

Clarify description of upgrade, and simplify the zpool.8 wording of
the zpool-upgrade(8) description.

Clarify description of import, detail what zpool-import(8) actually 
does.

Add appropriate SEE ALSO sections. Divided zpool subcommand manual 
pages need their own SEE ALSO sections. Also modified fsck.zfs.8 
to point directly to zfs-scrub.8 and zed.8.in to include a direct
reference to zfs-events.8
