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.

lualoader: fix setting of loader_color=NO in loader.conf(5)

Previously color.disabled would be calculated at color module load time,
then never touched again. We can detect serial boots beyond just what we're
told by loader.conf(5) so this works out in many cases, but we must
re-evaluate the situation after the config is loaded to make sure we're not
supposed to be forcing it enabled/disabled.

Discovered while trying to test r353872.

Instead return '', as the associated reset* functions will also return ''.
This should get rid of the funky '2' and '4' in the kernel selector if
you're booting serial.

loader: Respect loader_color=YES for serial consoles

It's not uncommon these days for the terminals attached to serial consoles
to support ANSI escape sequences. However, we assume escape sequences may
break some serial consoles and default to not using them when boot_serial or
boot_multicons (or if console contains "comconsole" in the forth loader) for
broader compatibility. We also have loader_color which can be explicitly set
to "NO" to disable the use of ANSI escape sequences.

The problem is that loader_color=YES gets ignored when boot_serial=YES or
boot_multicons=YES (or when console contains "comconsole" in the forth
loader).

To fix, the existing default behavior remains unchanged when loader_color is
unset, loader_color=NO explicitly disables the use of ANSI escape sequences
still, and the change is that loader_color=YES can now be used to explicitly
allow ANSI escapes when a serial console is enabled.

lualoader: More black-on-white fixes

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.

lualoader: Clear up some possible naming confusion

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.

CSI (30-37)m ... CSI 39m
CSI (40-47)m ... CSI 49m

- Provide resetf/resetb to match escapef/escapeb
- Use CSI 22m to undo a bold

This is a more reasonable approach than what was previously taken.

lualoader: Setup default color scheme if we're using colors

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.
