f698c1e99b zfsd: add support for hotplugging spares
If you remove an unused spare and then reinsert it, zfsd will now online
it in all pools.

Do not MFC without 2a58b312b6 (but it's ok to MFC that one without this
one).

9e5787d228 Merge OpenZFS support in to HEAD.
The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.

I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.

Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.

Improvements include:
  project quotas, encrypted datasets,
  allocation classes, vectorized raidz,
  vectorized checksums, various command line
  improvements, zstd compression.

Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

e5a4a83784 MFV r318941: 7446 zpool create should support efi system partition
illumos/illumos-gate@7855d95b30
7855d95b30

https://www.illumos.org/issues/7446
  Since we support whole-disk configuration for boot pool, we also will need
  whole disk support with UEFI boot and for this, zpool create should create efi-
  system partition.
  I have borrowed the idea from oracle solaris, and introducing zpool create -
  B switch to provide an way to specify that boot partition should be created.
  However, there is still an question, how big should the system partition be.
  For time being, I have set default size 256MB (thats minimum size for FAT32
  with 4k blocks). To support custom size, the set on creation "bootsize"
  property is created and so the custom size can be set as: zpool create B -
  o bootsize=34MB rpool c0t0d0
  After pool is created, the "bootsize" property is read only. When -B switch is
  not used, the bootsize defaults to 0 and is shown in zpool get output with
  value ''. Older zfs/zpool implementations are ignoring this property.

This commit makes no sense for FreeBSD, that is why I blocked the option,
but it should be good to stay closer to upstream.

d727d8b0b1 Optimize zfsd for the happy case
If there are no damaged pools, then ignore all GEOM events.  We only use
them to fix damaged pools.  However, still pay attention to ZFS events.

af63bbd0f0 zfsd: Don't spare a vdev that's being replaced
If a zfs pool contains a replacing vdev (either created manually by "zpool
replace" or by zfsd(8) via autoreplace by physical path) and then new spares
get added to the pool, zfsd shouldn't use one to replace the drive that is
already being replaced.  That's a waste of resources that just slows down
the rebuild.

12a88a3d63 zfsd should be able to online an L2ARC that disappears and returns
Previously, this didn't work because L2ARC devices' labels don't contain
pool GUIDs.  Modify zfsd so that the pool GUID won't be required:

lib/libdevdctl/guid.h
	Change INVALID_GUID from a uint64_t constant to a function that
	returns an invalid Guid object.  Remove the void constructor.
	Nothing uses it, and it violates RAII.

cddl/usr.sbin/zfsd/case_file.h
cddl/usr.sbin/zfsd/case_file.cc
	Allow CaseFile::Find to match a CaseFile based on Vdev GUID alone.
	In CaseFile::ReEvaluate, attempt to online devices even if the newly
	arrived device has no pool GUID.

cddl/usr.sbin/zfsd/vdev_iterator.cc
	Iterate through a pool's cache devices as well as its regular
	devices.

7a0c41d5d7 zfsd(8), the ZFS fault management daemon
Add zfsd, which deals with hard drive faults in ZFS pools. It manages
hotspares and replements in drive slots that publish physical paths.

cddl/usr.sbin/zfsd
	Add zfsd(8) and its unit tests

cddl/usr.sbin/Makefile
	Add zfsd to the build

lib/libdevdctl
	A C++ library that helps devd clients process events

lib/Makefile
share/mk/bsd.libnames.mk
share/mk/src.libnames.mk
	Add libdevdctl to the build. It's a private library, unusable by
	out-of-tree software.

etc/defaults/rc.conf
	By default, set zfsd_enable to NO

etc/mtree/BSD.include.dist
	Add a directory for libdevdctl's include files

etc/mtree/BSD.tests.dist
	Add a directory for zfsd's unit tests

etc/mtree/BSD.var.dist
	Add /var/db/zfsd/cases, where zfsd stores case files while it's shut
	down.

etc/rc.d/Makefile
etc/rc.d/zfsd
	Add zfsd's rc script

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c
	Fix the resource.fs.zfs.statechange message. It had a number of
	problems:

	It was only being emitted on a transition to the HEALTHY state.
	That made it impossible for zfsd to take actions based on drives
	getting sicker.

	It compared the new state to vdev_prevstate, which is the state that
	the vdev had the last time it was opened.  That doesn't make sense,
	because a vdev can change state multiple times without being
	reopened.

	vdev_set_state contains logic that will change the device's new
	state based on various conditions.  However, the statechange event
	was being posted _before_ that logic took effect.  Now it's being
	posted after.
