5f018c9147 libdevdctl: Force full match of "timestamp" field name
OpenZFS generates events with a "zio_timestamp" field, which gets mistaken for
"timestamp" by libdevdctl due to imprecise string matching.  Then later it is
assumed a "timestamp" field exists when it doesn't and an exception is thrown.

Add a space to the search string so we match exactly "timestamp" rather than
anything with that as a suffix.

47ce20aef1 libdevdctl: g++9 avoid Wdeprecated-copy
g++9 now warns about having defined an assignment operator but using the
default copy constructor, or vice versa.  Avoid the issue in libdevdctl
by just using the default assignment operator too.

2c3f47a727 Another round of attempting to squelch -Wdeprecated-declarations, which
has become very trigger-happy with libc++ 9.0.0.

It does not help that gcc's implementation of this warning is even more
trigger-happy, in the sense that it already warns on the declaration
itself, not when you are using it.  This is very annoying with our use
of -Wsystem-headers.  That should really be disabled for gcc.

23e2b4d9b1 Instead of disabling gcc's deprecated declaration warnings about e.g.
std::auto_ptr in a whole bunch of individual Makefiles, make the warning
globally non-fatal instead.  This is similar to what was done to many
more non-fatal warnings from newer gcc versions.

a07d59d1da zfsd: Allow zfsd to work on any type of GEOM provider
cddl/usr.sbin/zfsd/zfsd_event.cc
	Remove the check for da and ada devices.  This way zfsd can work on md,
	geli, glabel, gstripe, etc devices.  geli in particular is useful
	combined with ZFS.  gnop is also useful for simulating drive pulls in
	the ZFSD test suite.

	Also, eliminate the DevfsEvent class entirely.  Move its
	responsibilities into GeomEvent.  We can get everything we need to know
	just from listening to GEOM events.

lib/libdevdctl/event.cc
	Fix GeomEvent::DevName for CREATE events.  Oddly, the relevant field is
	named "cdev" for CREATE events but "devname" for disk events.

Relnotes:	Yes (probably worth mentioning the geli part)

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.
