efi, like the various ${MACHINE} directories, should have a dependency on
the enabled interpreters.
The general rule here is that any top-level directory that has a program at
any depth within that includes loader.mk should add ${INTERP_DEPENDS} added
to its dependencies so that the appropriate ficl/lua bits are ready before
they begin.
Note that the only directories in-tree that require it but will not get it
in a more appropriate manner are i386 (on amd64), efi, and userboot. i386
and userboot are handled explicitly in Makefile.amd64 where they are added
to S.yes.

lualoader was previously not processing \ as escapes; this commit fixes
that and does better error checking on the value as well.
Additionally, loader.conf had some odd restrictions on values that make
little sense. Previously, lines like:
kernel=foo
Would simply be discarded with a malformed line complaint you might not
see unless you disable beastie.
lualoader tries to process these as well as it can and manipulates the
environment, while forthloader did minimal processing and constructed a
`set` command to do the heavy lifting instead. The lua approach was
re-envisioned from building a `set` command so that we can appropriately
reset the environment when, for example, boot environments change.
Lift the previous restrictions to allow unquoted values on the right hand
side of an expression. Note that an unquoted value is effectively:
[A-Za-z0-9-][A-Za-z0-9-_.]*
This commit also stops trying to weirdly limit what it can handle in a
quoted value. Previously it only allowed spaces, alphanumeric, and
punctuation, which is kind of weird. Change it here to grab as much as it
can between two sets of quotes, then let processEnvVar() do the needful and
complain if it finds something malformed looking.
My extremely sophisticated test suite is as follows:
<<EOF
X_01_simple_string="simple"
X_02_escaped_string="s\imple"
X_03_unquoted_val=3
X_04_unquoted_strval=simple_test

Future work may provide a stub loader module in userland so that we can
formally test the loader scripts rather than sketchy setups like the above
in conjunction with the lua-* tools in ^/tools/boot.
There is no need to keep multiple copies of the relocation code. The
amd64 code works on arm64 with a few small changes to relocation types.

Handle malloc failures in vbe_init().
If it should so happen and we do get malloc failure in vbe_init(),
use original mode list.
Replace nitems with nentries to have naming consistency and avoid
confusion with nitems() macro.

Some systems may provide multiple GOP instances and not all are
bound to hardware. The current loader is picking up the first GOP,
which may not be usable. Instead we load the GOP handle array,
and test every handle to have registered ConOut protocol. If ConOut is
present, we can use this GOP handle to open GOP protocol.
This fixes the positioning of the "Welcome to FreeBSD" heading, which was
misplaced after the recent update to Lua 5.4. The issue was previously
masked by a compatibility knob in Lua 5.3 that would cause float-tagged
numbers to render faithfully without the decimal component. Lua 5.4 dropped
that and ensures that it always prints a decimal component, even if it has
to append a ".0" to the value.
Standard division produces a "float", floor division (//) can be used to
guarantee an integer. Floating point operations have been completely ripped
out of the liblua compiled for the bootloader, so this is a nop. This is
decidedly better than trying to hack out the float tag entirely.

We do select font based on desired terminal size, we do query
UEFI terminal size with conout->QueryMode(), but by mistake, the fallback
values are used.
Pass gfx_state to efi_find_framebuffer(), so we can pick between
GOP and UGA in efi_find_framebuffer(), also we can then
set up struct gen_fb in gfx_state from efifb and isolate efi fb data
processing into framebuffer.c.
This change does allow us to clean up efi_cons_init() and reduce
BS->LocateProtocol() calls.
A little downside is that we now need to translate gen_fb back to
efifb in bootinfo.c (for passing to kernel), and we need to add few
-I options to CFLAGS.
hw.vga.textmode is directing VT VGA backend to use text mode.
The default screen mode for BIOS loader is text, and default
screen mode for VT VGA backend is graphics (unless we are running on
hypervisor or hw.vga.textmode is set to 1). Using hw.vga.textmode
for loader does remove possibility to have graphical mode VT VGA with
text mode loader.
screen.textmode can have possible values "0" to disable text mode,
and "1" to set text mode.
Instead of trying to set reasonable register values, save significant
register values, then prepare for font upload and then restore
registers from saved data.
This seems to fix text mode for most cases where text mode breakage
was reported.
Draw console on efi.
Add vbe framebuffer for BIOS loader (vbe off, vbe on, vbe list,
vbe set xxx).
autoload font (/boot/fonts) based on resolution and font size.
Add command loadfont (set font by file) and
variable screen.font (set font by size). Pass loaded font to kernel.
Export variables:
screen.height
screen.width
screen.depth
Add gfx primitives to draw the screen and put png image on the screen.
Rework menu draw to iterate list of consoles to enamble device specific
output.
Probably something else I forgot...

Previously having ficl/liblua in LIB32LIST with their respective option
turned OFF would be relatively harmless, as we wouldn't act on it unless we
were building the non-32 variant. As of ac5f382a9d, however, these are
now used for dependencies in some cases and must reflect what's actually
going to be built.
buildworld already runs the stand build in parallel[1], so make it easier to
identify ordering issues by properly establishing dependencies or adding
.WAIT where needed.
Everything in stand/ relies on libsa, either directly or indirectly, because
libsa build is where the stand headers get installed and it gets linked in
most places.
Interpreters depend on their libs, machine dirs usually depend on top-level
libs that are getting built and at least one of the interpreter flavors.
For i386, order btx/libi386/libfirewire before everything else using a
big-ol-.WAIT hammer. btx is the most common dependency, but the others are
used sporadically. This seems to be where the race reporting on the mailing
list is- AFAICT, the following sequence is happening:
1.) One of the loaders gets built based on stale btx/btxldr
2.) btx/btxldr gets rebuilt
3.) installworld triggers loader rebuild because btx was rebuilt after
This seems like the most plausible explanation, as they've verified system
time and timestamps.
While we're here, let's switch stand/ over to a completely parallel build so
we can work out these kinds of issues in isolation rather than in the middle
of a larger build.

loader_conf_dirs is the supporting mechanism for the included
/boot/loader.conf.d directory. When lualoader finishes processing all of
the loader_conf_files it finds after walking /boot/defaults/loader.conf,
it will now check any and all loader_conf_dirs and process files ending
in ".conf" as if they were a loader.conf.
Note that loader_conf_files may be specified in a loader.conf.d config
file, but loader_conf_dirs may *not*. It will only be processed as specified
in /boot/defaults/loader.conf and any loader_conf_files that were loaded
from there.

luacheck rightfully complains that i is unused in the show-module-options
loop at the end (it was used for some debugging in the process).
We've added a new pager module that's compiled in, so declare that as an
acceptable global.
This effectively dumps everything lualoader knows about to the console using
the libsa pager; that particular lua interface was added in r368591.
A pager stub implementation has been added that just dumps the output as-is
as a compat shim for older loader binaries that do not have lpager. This
stub should be moved into a more appropriate .lua file if we add anything
else that needs the pager.
