loader: Make vidc_biosputchar static

It's currently unused outside of vidconsole.c. Gerald Hicks' fix to the
beep code from de37e4a6d2333/1998 introduced the funciton as
static. Maxim Sobolev (sobomax) made it non-static since his spinconsole
called it in c4c3b35172d67/2009. When sobomax dropped the direct call
after making spinconsole console independent in b35172d67/2017,
vidc_biosputchar remained a harmless unreferenced global. Make it static
once again.

teken: color #3 is yellow not brown - use TC_YELLOW as the name

The console escape code standard (ECMA-48) specifies color #3 (escape
code 33) as yellow. A brown console color is an artifact of the VGA
palette, which replaces dim (but not bright) yellow with brown.

loader: accept "yellow" as a named color

For historical reasons console color number 3 may be either yellow (most
consoles) or brown (VGA palette). The console escape code standard
uses "yellow", but teken color name constants appear to be based on the
VGA scheme and use TC_BROWN for color 3. Even so, the palette table
used 50,50,0 as the RGB percentage tuple, resulting in a dim yellow for
framebuffer consoles at the time teken was introduced.

Amusingly, in 19e2ce2d8367 the comment on the palette entry was changed
from "brown" to "dark yellow" but the colour itself was changed from
a pure yellow to being somewhat brown.

Apparently palette update while in text mode, will cause
some adapters to end up with blank display. Previous update had
condition reversed.

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

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.

Probably something else I forgot...
