Some time ago, the boot loader stopped polling for a key press during
the kernel and module loading prior to the transition to lua. Inspection
of the code shows the polling is no longer there. Document the change.

I think we should centralize documentation on the loader settings in one
manual, such a loader.8. The current proliferation is not obvious where
to find the documentation. To the user, these are all set in loader.conf
or at the loader prompt.

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).

stand/lua: always allow overriding with local config files

Files listed here are the last ones read. And /boot/loader.conf.local was
moved from loader_conf_files to local_loader_conf_files leaving only
loader.conf and device.hints in loader_conf_files by default.

The idea is to ensure local_loader_conf_files, i.e., /boot/loader.conf.local,
can always be used to override other user defined settings.

So the sequencing is now as follow:

1. Bootstrap:
/boot/defaults/loader.conf

2. Read loader_conf_files files:
/boot/device.hints
/boot/loader.conf

3. Read loader_conf_dirs files:
/boot/loader.conf.d/*.conf

lualoader: add support for .lua configuration files

If a file is specified in loader_conf_files that ends in '.lua', lualoader
will now load and execute that file. These may be used in place of a
traditional loader.conf to use more complicated logic, where some values
may be set based on others or based on the environment that the C bits has
left us with.

Lua scripts are run in a limited environment. In particular, it does not get
access to any modules or, in-fact, anything except environment variable.

A config.buildenv hook has been added so that a local module can add
whatever it may need to to the environment.

When a global var is set in the lua script, it does not immediately alter
the loader environment. Instead, the script's environment is initially
empty and processed only if the whole script executes successfully.
Effectively, a lua configuration file either takes effect or it does not,
an error will not leave it in a half-baked state.
