If rootfs isn't ZFS, current version will emit an error claiming so and fail
to initialize libbe. As a consumer, bectl -r (undocumented) can be specified
to operate on a BE independently of whether on a UFS or ZFS root.
Unbreak this for the UFS case by only erroring out the init if we can't
determine a ZFS dataset for rootfs and no BE root was specified. Consumers
of libbe should take care to ensure that rootfs is non-empty if they're
trying to use it, because this could certainly be the case.
Some check is needed before zfs_path_to_zhandle because it will
unconditionally emit to stderr if the path isn't a ZFS filesystem, which is
unhelpful for our purposes.
This should also unbreak the bectl(8) tests on a UFS root, as is the case in
Jenkins' -test runs.

First pass of support for multiple GIC ITS blocks with ACPI.
Changes are to:
* register the correct subset of interrupts with pic_register
in case of ACPI.
* initialize just the cpu interface for the first ITS, when
domain information is not avialable. This has to be done
until we split the per-CPU init to do LPI setup just once.
* remove duplicate check for the GIC ITS domain, the sc_cpus
are setup from domain, so the check again in per-CPU init
seems unnecessary.

This is a major update for pci_host_generic_acpi.c, the current
implementation has some gaps that are better fixed up in one go.
The changes are to:
* Follow x86 method of not adding PCI resources to PCI host bridge in
ACPI code. This has been moved to pci_host_generic_acpi.c, where we
walk thru its resources of the host bridge and add them.
* Fixup code in pci_host_generic_acpi.c to read all decoded ranges
and update the 'ranges' property. This allows us to share most of
the code with generic implementation (and the FDT one).
* Parse and setup IO ranges and bus ranges when walking the resources
above. Drop most of the changes related to this from acpica code.
* Add the ECAM memory area as mem resource 0. Implement the logic to
get the ECAM area from MCFG (using bus range which we now decode),
or from _CBA (using _BBN/bus range). Drop aarch64 ifdefs from acpica
code which did part of this.
* Switch resource activation to similar code as FDT implementation,
this can be moved into generic implementation in a later pass.
* Drop the mechanism of using the 7th bit of bus number as the domain,
this is not correct and will work only in very specific cases. Use
_SEG as PCI domain and use the bus ranges of the host bridge to
provide start bus number.
This commit should not make any functional change to dev/acpica/acpi.c

earlier additions in this file done for aarch64.

On arm64 (where INTRNG is enabled), the interrupts have to be mapped
with ACPI_BUS_MAP_INTR() before adding them as resources to devices.
The earlier code did the mapping before calling acpi_set_resource(),
which bypassed code that checked for PCI link interrupts.
To fix this, move the call to map interrupts into acpi_set_resource()
and that requires additional work to lookup interrupt properties.
The changes here are to:
* extend acpi_lookup_irq_handler() to lookup an irq in the ACPI
resources
* create a helper function acpi_map_intr() which uses the updated
acpi_lookup_irq_handler() to look up an irq, and then map it
with ACPI_BUS_MAP_INTR()
* use acpi_map_intr() in acpi_pcib_route_interrupt() to map
pci link interrupts.
With these changes, we can drop the ifdefs in acpi_resource.c, and
we can also drop the call for mapping interrupts in generic_timer.c

This quirk worked around a firmware bug that programmed the MSI-X bar

Add an undocumented -r option preceding the bectl subcommand to specify a BE
root to operate out of. This will remain undocumented for now, as some
caveats apply:
- BEs cannot be activated in the pool that doesn't contain the rootfs
- bectl create cannot work out of the box without the -e option right now,
since it defaults to the rootfs and cross-pool cloning doesn't work like
that (IIRC)
Plumb the BE root through to libbe(3) so that some things -can- be done to
it, e.g.
bectl -r tank/ROOT create -e default upgrade
bectl -r tank/ROOT mount upgrade /mnt
this aides in some upgrade setups where rootfs is not necessarily ZFS, and
also makes it easier/possible to regression-test bectl when combined with a
file-backed zpool.

libbe(3) currently uses zfs_be_root and locates which of its children is
currently mounted at "/". This is reasonable, but not correct in the case of
a chroot, for two reasons:
- chroot root may be of a different zpool than zfs_be_root
- chroot root will not show up as mounted at "/"
Fix both of these by rewriting libbe_init to work from the rootfs down.
zfs_path_to_zhandle on / will resolve to the dataset mounted at the new
root, rather than the real root. From there, we can derive the BE root/pool
and grab the bootfs off of the new pool. This does no harm in the average
case, and opens up bectl to operating on different pools for scenarios where
one may be, for instance, updating a pool that generally gets re-rooted into
from a separate UFS root or zfs bootpool.
While here, I've also:
- Eliminated the check for /boot and / to be on the same partition. This
leaves one open to a setup where /boot (and consequently, kernel/modules)
are not included in the boot environment. This may very well be an
intentional setup done by someone that knows what they're doing, we should
not kill BE usage because of it.
- Eliminated the validation bits of BEs and snapshots that enforced
'mountpoint' to be "/" -- this broke when trying to operate on an imported
pool with an altroot, but we need not be this picky.

We generally document shutdown(8) instead of reboot(8) as it's better for
interactive use.
In modern FreeBSD is matters a lot less, it's mostly just convention. One
minor thing is that shutdown(8) produces a global message, while reboot(8)
does not. It is believed that historically, some versions of reboot did not
do appropriate safe shutdown checks and just rebooted.
It's also just consistency: for example the handbook[1] documents shutdown.
There is actually another important difference between reboot and shutdown
-r now: reboot does not run /etc/rc.shutdown. This is because reboot has
its own shutdown procedure and does not signal init like init 6 and
shutdown -r now do (except in the case of rerooting via reboot -r).
A few years ago jilles@ proposed changing reboot's default to signalling
init (preserving reboot -q which just invokes the reboot system call), but
this was not accepted. Perhaps this can be tried again for 13.0.
