U-Boot setup a few variables :
- fdt_addr which is the board static dtb (most of the time loaded before
u-boot or coming from some hardware like a ROM)
- fdt_addr_r which is a location in RAM that holds the DTB loaded by
u-boot or before u-boot
In the case of u-boot + rpi firmware the DTB is loaded in RAM but the location
still end up in the fdt_addr variable and the fdt_addr_r variable exist.
Change the behavior so we test that a DTB exists for every possible variable :
- fdt_addr_r is checked first as if u-boot needed to modify it the
correct DTB will live there.
- fdt_addr is checked second as if we run on a hardware with DTB in ROM
it means that we what/need to run that
- fdtaddr looks like a FreeBSD-ism but since I'm not sure leave it.

Previously the code cut those fields on second colon, that prevented
boot from boot environments with colon in their names. This change
moves the limitation from dev field to path, which is empty by default.

If a disk is of an oddball size, like the 200mb + 512b used in rootgen.sh,
when disk_open() is called on a GELI encrypted partition, attempts to read
the partition table fail, as they pass through the decryption process which
turns the already plaintext data into jibberish.
When reading the partition table, always pass a slice and partition setting
of -1, and an offset of 0. Setting the slice to -1 prevents a false
positive when checking the slice against the cache of GELI encrypted
slices.

While in base we use it as a boolean (of the wrong spelling), there's
at least one out of tree user that needs it to be int since priorirty
is a small int, not a 0/1. In deference to the time it's wasted me and
my team, push this up into FreeBSD for whatever short life boot1 may

I will likely bring this back as an optional feature, similar to

Reduce by 1 the number of crazy libraries we need in stand by moving
geli into libsa (where architecturally it belonged all along). This
just moves things around without any code changes.
Normally the serial console is not enabled until /boot.config is read and
we know how the serial console should be configured. Initialize the
consoles early in 'dual' mode (serial & keyboard) with a default serial
rate of 115200. Then serial is re-initialized once the disk is decrypted
and the /boot.config file can be read.
This allows the GELIBoot passphrase to be provided via the serial console.

The GELI boot code rounds reads up to 4k, since the encrypted sectors are
4k, and must be decrypted as a unit. With oddball sized disks (almost
always virtual), this can lead to reading past the end of the disk.

`rdev` and `disk` serve the same purpose, read the partition table without
the `d_offset` or `d_slice` set, so the read is relative to the start of
the disk. Reuse the already initialized `disk` instead of making another
copy later.

callback to do the checks.
This will allow us to have a more graceful fallback code. In the
future, it's anticipated that we may fallback to a more global search
(or implement a command to do so) when reqeusted by the user, or we
detect a violation of the UEFI Boot Manager protocol severe enough to
warrant this backstop. For now, it just allows us to get rid of img as

To recap the problem: with a black-on-white xterm, the menu draws terribly.
Ideally, we would try our best for a white-on-black context for the menu
since graphics and whatnot might not be tested for other setups and there's
no reasonable way to sample the terminal at this point for the used color
scheme.
This commit attempts to address that further in two ways:
- Instead of issuing CSI bg/fg resets (CSI 39m and CSI 49m respectively for
"default"), issue CSI bg/fg escape sequences for our expected color scheme
- Reset to *our* default color scheme before we even attempt to load the
local module, so that we personally don't have any earlier text with the
console default color scheme.

dteske@, I believe, had originally pointed out that lualoader failed to
allow logo-*.lua for new logos to be added. When correcting this mistake, I
failed to do the same for brands.
Correct the sub-mistake: creating new brands is almost identical to creating
new logos, except one must use `drawer.addBrand` and 'graphic' is the only
valid key for a branddef at the moment.
While here, I've added `drawer.default_brand` to be set to name of brand to
be used (e.g. 'fbsd', project default).
Eventually this whole goolash will be documented.

We support both of the following cases of substitution:
bar="y"
foo="${bar}"
foo="$bar"
The latter substitution syntax is, of course, not recommended- all
punctuation must be considered potential variable names, and we do not go
through the effort of searching the different combinations of, for instance,
"$x.y.z" to determine if the variable is $x, $x.y, or $x.y.z.
This is not officially documented as supported, but it has worked in
forthloader for what is most likely a long time as `evaluate` is used to
process the right hand side of the assignment.
loader.conf(5) documents loader_conf_files to mean "additional configuration
files to be processed right after the present file." However, lualoader
ignored loader_conf_files after processing /boot/defaults/loader.conf.
Rewrite these bits to process loader_conf_files after each loaded file.
e.g. boot_mute, boot_single, boot_verbose, and friends; we checked for these
in multiple places, consolidate into common/ and allow a setting of "NO" for
any of these to turn them off. This allows systems with multiple
loader.conf(5) or loader.conf(5) overlay systems to easily turn off
variables in later processed files by setting it to NO.

This will not be executed on reload, though later work could allow for that.
It's intended/expected that later work won't generally need to happen on

config is reloaded but not upon the initial load.
r330809 replaced duplication of devdesc struct fields with an embedded copy
of the devdesc struct, to avoid fragility. That means all the scattered
