When migrating the firmware to be installed as plain firmware files

The follow-up change to defaults/loader.conf is also consistently
missing the "fw".

Fix both places, and add the wrongly spelt version to ObsoleteFiles.inc
(entirely untested).

loader: add nvidia modules to the loader blacklist

It is known that nvidia modules, like the drm modules that are already
present, will panic if loaded in early boot rather than later. Pop them
into our list to deny loading them if someone were to add, e.g.,
nvidia-modeset_load="YES", to their loader.conf. This doesn't prevent
them from being loaded if one drops to the loader prompt, but it does
prevent the standard user from easy foot-shooting if they find old or
inaccurate information out in the wild.

loader.conf: add LinuxKPI based wireless drivers to module_blacklist

Despite being discouraged in the man page people are trying to load
the driver from loader. In that case firmware is missing and the
root file system is not there yet and the LinuxKPI based drivers
will panic the system on boot. Simply avoid any further support
trouble by disallowing them to be loaded from loader.
If someone still wants to do it, they will need to figure out how
to remove them from the blocklst and how to loader the firmware
file(s) in advance themselves.

lualoader: allow graphical bits to be disabled with loader_gfx

Some people prefer the old ASCII art look and it's good to have a way
to confirm that the fallbacks still work right on systems that have a
functional framebuffer available. Add a loader_gfx loader.conf(5)
variable to disable the eager use of graphics for these use-cases.

While we're here, clean up the style in the area a little bit; the early
porting that I did to lualoader did a lot of redundant ~= nil that has
carried over into some of the later work. We can drop some of that, and
also re-organize some of these variables to improve readability.

ziaee notes that the positioning of the orb is a bit off; this is due to
a change in positioning that happened in
1b4e1171315398dec ("loader: Fix orb position") to account for the image
dimensions. This should be partially reverted to get it right; we
shouldn't assume that we can use the same shift in gfx-* definitions for
both the ASCII art and the associated image -- the {image, image_rl}
pair should be converted to something more like an fbimg or gfx table
that has the image, image width and a shift override to avoid messing
up the ASCII positioning when disabled (or with no graphics available).

loader: Set twiddle globaldiv to 16 by default

Booting FreeBSD on an EC2 c5.xlarge instance, the loader "twiddles"
810 times over the course of 510 ms, a rate of 1.59 kHz. Even accepting
that many systems are slower than this particular VM and will take
longer to boot (especially if using spinning-rust disks), this seems
like an unhelpfully large amount of twiddling when compared to the
~60 Hz frame rate of many displays; printing the twiddles also consumes
roughly 10% of the boot time on the aforementioned VM.

Setting the default globaldiv to 16 dramatically reduces the time spent
printing twiddles to the console while still twiddling at roughly 100
Hz; this should be ample even for systems which take longer to boot and
consequently twiddle slower.

Note that this can adjusted via the twiddle_divisor variable in
loader.conf, but that file is not processed until nearly halfway
through the loader's runtime.

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.

Preload hostuuid for early-boot use

prison0's hostuuid will get set by the hostid rc script, either after
generating it and saving it to /etc/hostid or by simply reading /etc/hostid.

Some things (e.g. arbitrary MAC address generation) may use the hostuuid as
a factor in early boot, so providing a way to read /etc/hostid (if it's
available) and using it before userland starts up is desirable. The code is
written such that the preload doesn't *have* to be /etc/hostid, thus not
assuming that there will be newline at the end of the buffer or even the
exact shape of the newline. White trailing whitespace/non-printables
trimmed, the result will be validated as a valid uuid before it's used for
early boot purposes.

The preload can be turned off with hostuuid_load="NO" in /boot/loader.conf,
just as other preloads; it's worth noting that this is a 37-byte file, the
overhead is believed to be generally minimal.

It doesn't seem necessary at this time to be concerned with kern.hostid.

One does wonder if we should consider validating hostuuids coming in
via jail_set(2); some bits seem to care about uuid form and we bother
validating format of smbios-provided uuid and in-fact whatever uuid comes
from /etc/hostid.
