LLVM12 complains if you change the symbol binding:
`error: _longjmp changed binding to STB_GLOBAL`
In this case LLVM actually ignored the weak directive and used the
later .global, but GNU as would mark the symbol as weak.
None of the other architectures mark the libsa _setjmp as weak so
just drop this directive.
Parentheses added to HASZERO macro to avoid a GCC warning, and formatted
with clang-format as we have adopted these and don't consider them
'contrib' code.

The integer arrays are encoded in nvlist as counted array <count, i0, i1...>,
loader xdr_array() is missing the count. This will affect the pool import when
there are hole devices in pool.
Also fix the new data add and print functions.
Follow-up to r353959 and r368070: do the same for other architectures.
arm32 already seems to use its own .fnstart/.fnend directives, which
appear to be ARM-specific variants of the same thing. Likewise, MIPS
uses .frame directives.

We don't have NEON available in the boot loader, so we have to disable
it. OpenZFS included ZSTD which used the wrong symbol to bring in neon
support. Change to use the code that's been submitted upstream as a
pull request to both.
__ARM_NEON is the proper symbol, defined in ARM C Language Extensions
Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
sources suggest __ARM_NEON__, but that's the obsolete spelling from
prior versions of the standard.

ZSTD Pull Request: https://github.com/facebook/zstd/pull/2356
We are using asize property from pool label and we do not depend
on partition data to find last two pool labels and to validate LBA for disk IO.
This does allow us to re-enable support for partitionless disk setups.
The OpenZFS code that uses the BMI instructions is broken. Forcibly
disable them to prevent their use. When enabled, the build breaks.
This fixes the build when compiled for a core with BMI instructions.
This is the same fix committed in r364777, for the same issue.

Add support to the _STANDALONE environment enough bits of the kernel
that we can compile it. We still have a small zstd_shim.c since there
were 3 items that were a bit hard to nail down and may be cleaned up
in the future. These go hand in hand with a number of commits to
sys/sys in the past weeks, should this need be MFCd.

OpenZFS will start using some of the kernel timekeeping bits
shortly. This implements the bare minimum of that which currently
is just the time_seconds variable.
During devswitch probe, we pick boot pool based on boot disk, if the boot
disk happens to have multiple pools in freebsd-zfs partitions, the current
code does pick last pool from boot disk as boot pool. While there is no
way at that stage to test, the more logical approach would be to pick
first matching pool.
This patch is assuming we do pass pool guid pointer with guid value 0,
this will help us to determine, if the guid value is already set or not.
The general suggestion would be not to share disk between different pools.

There was a small window cp was broken. Work around this by using :>
instead of cp /dev/null. Ideally, we'd keep the cp /dev/null in the
build as a regression test, but doing so breaks people that upgraded
during the cp breakage and this is simpler than bootstrapping a
working cp since there's no good __FreeBSD_version sign posts for
that.

Too stubborn for his own good: imp
bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.
By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.
By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.
bootonce dataset name is recorded in boot pool labels, bootenv area.
in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.
bootonce and nextboot features are usable in both UEFI and BIOS boot.
To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).
At this time, only lua loader is updated.

Please note that neither zstd nor encryption is
supported by the loader at this instant. This
change makes it safe to use those features in
one's root pool, but not in one's root dataset.
It can be useful to know what type of machine we are running on for desktop

It also allow us to support all the DMI variable that linux driver can fetch.

The checkpoints are another way of keeping the state of ZFS.
During the rewind, the pool has to be exported.
This makes checkpoints unusable when using ZFS as root.
Add the option to rewind the ZFS checkpoint at the boot time.
If checkpoint exists, a new option for rewinding a checkpoint will appear in
the bootloader menu.
We fully support boot environments.
If the rewind option is selected, the boot loader will show a list of
boot environments that existed before the checkpoint.

We should have nextboot feature implemented in libsa zfs code.
To get there, I have created zfs_nextboot() implementation based on
two sources, our current simple textual string based approach with added
structured boot label PAD structure from OpenZFS.
Secondly, all nvlist details are moved to separate source file and
restructured a bit. This is done to provide base support to add nvlist
add/update feature in followup updates.
And finally, the zfsboot/gptzfsboot disk access functions are swapped to use
libi386 and libsa.
