Replace renumber.pl with hextosrc.c. Improved TTF.

* Introduce VERSION and HASH for utility programs.
* Fontlint complained about the + in BDF U+1234 character names, so
  I changed them to U1234.

+### What about the TrueType gallant.ttf?
+
+Some systems no longer support BDF (or PCF) fonts. The days of raster
+fonts are numbered, it would seem. With high DPI displays these days,
+rendered anti-aliased fonts are the new norm.
+
+The `gallant.ttf` file is a conversion from BDF to TTF using
+[FontForge](https://fontforge.org/en-US/). (See the
+[GNUmakefile](GNUmakefile) for the scripted command sequence.) A TTF
+font can contain a raster font at its design size; sometimes this is
+called a *bit strike*. On systems supporting TrueType you may be able to
+use Gallant. The font family name is `Gallant12` to disambiguate it from
+`gallant` and to indicate that the design size is 12. Usage example with
+xterm:
+
+```
+xterm -fa Gallant12:size=12
+```
+
+You *can* use a larger `size` value, but that will only affect the line
+spacing, not the glyph size. Visually this is most apparent in the box
+drawing characters, where there will be vertical gaps. The same applies
+to all glyphs that connect to glyphs above and below, such as large
+parentheses, braces, brackets, integrals, etc.
