In two places we use '0' for a column number. However, the upper left
hand corner of the screen is 1, 1. Fix those two confusions. Also, fix
a comment that flipped the coordinates in a comment (I'm used to the
vt100 convention where it's row, column (eg y, x)) and didn't notice
the rest of the code uses x, y.

Remove /^--\n--\s*\$FreeBSD\$.*$\n/

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

When colors are disabled, color.escape{fg,bg} would return the passed in
color rather than the proper ANSI sequence for the color.
color.escape{fg,bg} would be wrong.
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.

Remove a bunch of special cases for UEFI and serial consoles. We do
want to do curses and menu things here. This makes us match what we do
in FORTH, with the possible exception of boxes around menus.

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.

r330282 registered loader.printc as printc, so use it instead. This makes
sense for a couple reasons, the major point being that it reads a little bit
easier and pairs nicely with the global 'print'.
Similar cases can not really be made for other loader.* functions as most of
them are either highly specific to our use-case or usually available in
other modules, such as `os`. printc does not have a standard implementation
in the Lua world(*), so we have a little more leeway with it, and it's kind
of a special case of the globally available 'print'.
(*) I've been in the Lua world for all of two weeks, so this could be wrong.

- Add screen.default_x and screen.default_y to determine where
screen.defcursor resets the cursor to.
- Use screen.setcursor in screen.defcursor instead of rewriting the escape
sequence.
- Use screen.default_y when resetting the cursor after writing the new
twiddle character, add a comment verbally describing the position just in
case.

It worked on my test setup, but is clearly non-functional on others.
Further examination of check-password.4th showed that it actually reset the
cursor to 0,25 every time and overwrote the previous password prompt. Do
that, and also clear the "Incorrect Password" text if the correct password
gets entered.

With exception to drawing bits, which should probably be kept as-is to not
make a mess out of things.

This gives some form of feedback while typing, and matches-(ish*) Forth
behavior. The cursor generally rests two column after the password prompt,
then the twiddle is drawn three columns later and the cursor reset to
resting position after being drawn.
I've removed the note about re-evaluating it for security considerations and
instead set it up as a module-local variable that we can set later depending
on environment or something. It's set to false with no chance of changing at
the moment.
*As close as I can tell from reading check-password.4th, because I don't
have an easy test (or deployed) setup for forth loader to check how close
it is. Please do mention if it's not close enough.

screen was also guilty of not-so-great argument names, but it was also
guilty of handling color sequences on its own. Change those bits to using
the color module instead.
As a side note, between color and screen, I'm not 100% sure that returning
the color_value is the right thing to do if we won't generate the escape
sequences. This should be re-evaluated at a later time, and they should
likely return nil instead.

luaconf.h has a LUA_COMPAT_FLOATSTRING option that may be defined to do this
instead of needing intstring.

This was also a convenience convention (for me) that is not very lua-tic.
Drop it.
I've maintained some parentheses where I'd prefer them, for example,
'if x or y or (z and w) then', but these situations are far and few between.

This was previously chosen out of convenience, as we had a mixed style and
needed to be consistent. I started learning Lua on Friday, so I switched
everything over. It is not a very lua-nic convention, though, so drop it.
Excessive parenthesizing around conditionals is next on the chopping block.

We follow pretty closely the following structure of a module:
1. Copyright notice
2. Module requires
3. Module local declarations
4. Module local definitions
5. Module exports
6. return
Re-organize the one-offs (config/drawer) and denote the start of module
exports with a comment.
Notes:

Declare these adjacent to the local definitions at the top of the module,
and make sure they're actually declared local to pollute global namespace a
little bit less.

These are the style points that I'd like to try and maintain in our lua
scripts:
- Parentheses around conditionals
- Trailing semicolons, except on block terminators
- s:method(...) instead of string.method(s, ...) where applicable
There's likely more, but that'll get hammered out as we continue.

Decimals screw up the escape sequence and the cursor will not get set. Right
now this only affects setting the cursor for drawing "Welcome to FreeBSD" --
the resulting number after our (x+(w/2)-9) calculation gets output as
"14.0."
This should be fixed at the interpreter level, rather than here, but this is
not a widespread problem at the moment so we'll fix it up in further work.
