0f17b429d0 vtfontcvt: initialize another variable to quiet GCC warning 
I believe this case could be triggered by a broken .bdf font.

24dd375e25 vtfontcvt: exit on error if the input font has too many glyphs 
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.

ccfb965433 Add META_MODE support. 
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.

b410b62c85 vt fontcvt: move to usr.bin/vtfontcvt 
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.
