remove accidentally left in debug goop

use uint8_t for all 8bit masks and data to avoid sign extending weirdness
found by running this on hppa with gcc12

add support for doubling a font's size, with optional smoothing
- works only on fonts up to 8 pixels wide for now
- smoothing attempts to detect pixel staircases and add pixels to smooth
them out

include glyph name in -d output

put back quotation mark removal in FAMILI_NAME statement which got broken
in a previous commit

keep track of character names and dump them into the header file if known

do not rely on every STARTCHAR/ENDCHAR sequence starting with ENCODING - the
standard doesn't specify in which order each glyph's properties are listed

- cast to unsigned char for ctype macros
- some warn/err improvements

rename a local variable so it doesn't conflict with a global one
NFC

remove debug printf()

error out on proportional fonts, provide option to override

add -N option to override the font's name

limit the comment width in the header output to the size of the character cell

if there are comments in the bdf copy them into the header output

use [] instead of # to represent pixels in the header output, this way pixels
are somewhat closer to square and the preview looks closer to the actual
output.
suggested by uwe@

add -h option to write font data as a header file that can be compiled
into a kernel

move \n where it's supposed to be
now fonts wider than 8 are dumped correctly

fix tpyo - now we draw characters with a smaller bounding box than the
character cell correctly, like term14.bdf

add -d option to dump rendered characters to the console

- convert remaining error output to err()
- suppress console output unless -v is specified

bdfload: Teach it to write wsf font files.

wsfontload(8) now groks simple "wsf" file format - that is basically a
header of kinda struct wsdisplay_font but with string fields embedded
and numeric fields in little-endian and font data afterwards.

Teach bdfload to write out such files if -o file.wsf argument is
specified.

While here fix a couple of bugs too (sorry, should have been separate
commits). Fix an off by one in numchars calculations. Fix the type
of buflen.

bdfload: g/c trailing whitespace

a crude BDF font loader for wsdisplay
