1ef64e3da5 loader: add aarch64 support for zstd
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

e694696956 Force __BMI__ experimental instructions off.
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.

9257c69b1c Turn off zstd on aarch64
loader support for zstd and zfs doesn't work for aarch64. Disable it
to unbreak the build.

2fec3ae896 Add zstd support to the boot loader.
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.

e307eb94ae loader: zfs should support bootonce an nextboot
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.

3830659e99 loader: create single zfs nextboot implementation
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.

e499793e76 Remove duplicate lz4 implementations
Port illumos change: https://www.illumos.org/issues/11667

Move lz4.c out of zfs tree to opensolaris/common/lz4, adjust it to be
usable from kernel/stand/userland builds, so we can use just one single
source. Add lz4.h to declare lz4_compress() and lz4_decompress().

b8902de147 Move ZFS files into libsa
Move the libzfs stuff into libsa. There's no need for it to be a
separate library. The separate library adds to the issues of build
ordering that we see from time to time. Move the filesystem support
into libsa, like all the other filesystem support rather than making
zfs the odd-duck out.
