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.

d53ed73590 Fix video on PCI heuristic
The video on PCI heuristic was broken. It was supposed to infer a
video device when the last element of the path was a PCI DEVICE PATH
node. However, the last node in the device path is an END node, so
this heuristic never fired.

This leads, among other things, to bhyve only producing output in the
serial connection once we leave the boot loader. This restores the
dual headed boot on bhyve + UEFI (as we did in 11.2), but will favor
serial in the absence of other config which may be a change from 11.2.

867ae3c38d loader: zfs_probe_dev should pick first matching zfs pool
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.

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.

277f38abff zfs: add an option to the bootloader to rewind the ZFS checkpoint
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.

4f8212c8b2 loader: Avoid -Wpointer-to-int cast warnings for Arm and RISC-V
On RISC-V, Clang warns with:

    cast to smaller integer type 'unsigned int' from 'void (*)(void *)'

Instead, use %p as the standard format specifier for printing pointers.
Whilst Arm's pointer size is the same as unsigned, it's still cleaner to
use the right thing there too.

2192efc03b RISC-V boot1.efi and loader.efi support
This implementation doesn't have any major deviations from the other EFI
ports. I've copied the boilerplate from arm and arm64.

I've tested this with the following boot flows:
OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD
OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD

Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required,
as the HSM extension is needed to bring them up explicitly. Because of this,
using BBL as the SBI implementation will not be possible. Additionally, there
are a few recent u-boot changes that are required as well, all of which will be
present in the upcoming v2020.07 release.

12c470af75 boot1.efi: use malloc family from libsa
The zfs reader development did reach to the point where linking boot1,
we will get errors about duplicate symbols Malloc, Free, Calloc.

We can just use libsa version, just as loader.efi does. The only concern is,
libsa zalloc is using fixed size heap region, I did pick 64MB as other
stage instances are using, but this size is likely not optimal. In any case,
with limited memory setups, we should boot loader.efi directly.

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.

the node length is large enough so no two nodes overlap.

While here return failure on malloc failure rather than a NULL pointer

afc571b1a6 veloader use vectx API for kernel and modules
The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.

For doing an install via loader, avoiding the need to rewind
large files is critical.

This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform.  On a fast VM we see 6% improvement.

For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().

For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.

Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.
