Commit e7fd9688ea changed vtfontcvt's command line parsing, but did
not correctly update the usage (it omitted the new -o flag).

Prepare support to be able to handle font data in loader, consolidate
data structures to sys/font.h and update vtfontcvt.
vtfontcvt update is about to output set of glyphs in form of C source,
the implementation does allow to output compressed or uncompressed font
bitmaps.

vtfontcvt: improve .bdf validation
Previously if we had a FONTBOUNDINGBOX or DWIDTH entry that had missing
or invalid values and and failed sscanf, we would proceeded with
partially initialized bounding box / device width variables.

NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are
polled, have terrible performance and just for ancient arm
hardware. NAND parts have evolved significantly from this early work
and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

Previously if we had a BBX entry that had invalid values (e.g. bounding
box outside of font bounding box) and failed sscanf (e.g., because it
had fewer than four values) we skipped the BBX value validation and then
triggered an assertion failure.

Previously we would crash if the BBX y-offset was outside of the font
bounding box.

I believe this case could be triggered by a broken .bdf font.

The kernel has a limit of 131072 glyphs in a font; add the same check to
vtfontcvt so that we won't create a font file that the kernel will not
load.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

vtfontcvt is useful for end users to convert arbitrary bitmap fonts
for use by vt(4). It can also be used as a build tool, allowing us
to keep the source font data in the src tree rather than uuencoded
binaries.
