This pertains exclusively to the set/restore functionality that we offer,
where any changes made by loader.conf previously will be effectively removed
upon reload of the configuration. We don't currently have a need to export
these, so don't bother.
Not all systems use efifb; pull hw.vga.textmode and choose a good console
mode instead if it's set to something non-zero. This is basically a revival
of the code that used to live in boot1, but instead rebased onto this
different way of doing mode selection in loader.efi.
Interestingly enough, the regression that was previously introduced where
GOP would not reflect the console setting does not seem to exist when
console mode selection is done here. I've not done any investigation as to
why this is the case. Nevertheless, boot1.efi is still not the best place to
do mode selection.
Default the max resolution to 1080p, we'll accept Width x Height
specifications along with the following presets:
- 480p
- 720p
- 1080p
- 2160p or 4k
- 5k

I thought I tested this scenario, but clearly I failed to. =(
BIOS boots won't have efi-autoresizecons, so trying to use it as a forth
word fails during include. Use evaluate on "efi-autoresizecons" as a string
instead to move any potential errors to runtime- safely after we've already
checked that we're booting UEFI.
Pointy hat to: me

r331321 delegated autoresizing to an efi-autoresizecons command that
currently is expected to be done in forth/lua prior to drawing anything
useful.
Add the Forth version of the lua addition in r331321, hook efi.4th up to be
installed.
efiboot? was written by dteske@; anything outside of that may be blamed on
me.
boot1 is too early to be deciding a good resolution. Console modes don't map
cleanly/predictably to actual screen resolutions, and GOP does not reflect
the actual screen resolution after a console mode change. Rip it out.
Add an efi-autoresizecons command to loader to choose an optimal screen
resolution based on the current environment. We'll explicitly execute this
later, preferably before we draw anything of value but after we load config
and pick up any tunables we may need to decide where we're going.
This method also allows us to actually pass the correct framebuffer
information on to the kernel.
UGA autoresizing is not implemented because it doesn't have the kind of mode
enumeration that GOP does. If an interested person with relevant hardware
could get in contact, we can take a look at implementing UGA autoresize.
This effectively "fixes" the breakage caused by r327058, but doesn't
actually set the resolution correctly until the interpreter calls
efi-autoresizcons. The lualoader version of this has been included for
reference; the forth equivalent will follow.

In the original lualoader project, 'escapef' and 'escapeb' were chosen for
'escape fg' and 'escape bg'. We've carried on this naming convention, and as
our use of attributes grow the likeliness of 'escapeb'/'resetb' being
confused upon glance for 'escape bold'/'reset bold' increases.
Fix this by renaming these four functions to {escape,reset}{fg,bg} rather
than {escape,reset}{f,b} for clarity.

See: comments in the hook module about intended usage, as well as the
introduced use for config.reloaded.
Use the newly introduced hook module to define a "config.reloaded" hook.
This is currently used to register core's clearKernelCache as a reload hook
to avoid a circular dependency and fix this functionality- it didn't
actually work out, and it isn't immediately obvious how it slipped into src.
Other hook types will be introduced into the core lualoader as useful hook
points are identified.
Previously, we sent a CSI 0m sequence to reset attributes, which also reset
the color scheme if the terminal defaults didn't match what we're expecting.
Go all-in and reset the color scheme, too, just in case.

The former is fairly vague; these are FDT overlays to be applied to the
running system, so /boot/dtb is a sensible location to put it without
cluttering up /boot/dtb even further if desired.
The console may have been set for different colors before lualoader kicks
in; notably, a black-on-white color scheme is not necessarily what we're
expecting.
While here, make color.default() a composition of color.escape() instead of
rewriting the escape sequence to make it more obvious what it's achieving: a
white-on-black color scheme with no attributes set.

lualoader in itself only uses another ~200K, but there seems to be no reason
not to bump it a little higher to give us some more wiggle room.
With this, I can boot using a menu-enabled lualoader, no problem and
reasonably fast. Some heap usage datapoints from the review:
forthloader, no menus, kernel loaded:
heap base at 0x1203d5b0, top at 0x1208e000, used 330320
lualoader, no menus, kernel loaded:
heap base at 0x42050028, top at 0x420ab000, used 372696
lualoader, menus, kernel loaded:
heap base at 0x42050028, top at 0x420d5000, used 544728
Since then, the no menu case for lualoader should have decreased slightly as
I've made some changes to make sure that it no longer loads any of th emenu
bits with beastie disabled.
While here, split heap size out into a HEAP_SIZE macro.

This fixes a problem encountered on the Lenovo Thinkpad X220/Yoga 11e where
runtime services would try to inexplicably jump to other parts of memory
where it shouldn't be when attempting to enumerate EFI vars, causing a
panic.
The virtual mapping is enabled by default and can be disabled by setting
efi_disable_vmap in loader.conf(5).

A foolish consistency is the hobgoblin of little minds, adored by
little statesmen and philosophers and divines. With consistency a
great soul has simply nothing to do. -- Ralph Waldo Emerson
The current system is fragile and requires very careful layout of all
*_devdesc structures. It also makes it hard to change the base
devdesc. Take a page from CAM and put the 'header' in all the derived
classes and adjust the code to match.
For OFW, move the iHandle h_handle out of a slot conflicting with
d_opendata. Due to quirks in the alignment rules, this worked.
However changing the code to use d_opendata storage now that it's a
pointer is hard, so just have a separate field for it.
All other cleanups were to make the *_devdesc structures match where
they'd taken some liberties that were none-the-less compatible enough
to work.
open_disk uses d_opendata for it's own purpse. We can't store blkio
there. Fortunately, blkio is stored elsewhere and we never actually
retrieve blkio from d_opendata. Eliminate it as a source of confusion.
Eliminate all stores of d_opendata in efi since this layer doesn't own
that field.
Make sure { on the same line as struct for all struct *devdesc. Move
some type definitions to next to the dv_type define, since that's what
sets the d_type.
This matches a convention that we use, at least in ubldr, to prefix
getc/putc with a loader-specific prefix to avoid collisions. This was
encountered while trying to build the beri loader with MK_LOADER_LUA=yes.

With autodetection turned on, hitting the filesystem everytime we need to
calculate choices for the kernel carousel is kind of slow. Cache once on the
first listing and reload it anytime the config is reloaded in case any of
the loader.conf(5) changes that affect this (kernel, kernels,
kernels_autodetect) have changed. This also picks up the case where we've
changed currdev and the autodetected kernels could change.
cli_execute was changed to return the status, cascade that to
cli_execute_unparsed.
This fixes a lot of false "Failed to execute" errors following r330620; no
failures actually occurred, but [module]_error would've then promptly
executed (and also "failed")
These tend to have less coverage in other places and they don't have
defaults as of yet, so mention them here:
- fdt_overlays
- kernels_autodetect (lualoader only)
