[PATCH] gnu: Add ttf-dejavu

Hello all,

This font is derived from Bitstream Vera but includes glyphs for more
languages and also includes a serif font family.  The latin sans-serif
and monospace is the same as Bitstream Vera, or at least I'm not aware
of any difference.  It's a drop-in replacement with no downsides.

If you install this, I suggest that you remove the ttf-bitstream-vera
package at the same time, so that generic font names such as "Monospace"
will henceforth refer to DejaVu.  Emacs users will notice a big
improvement in the look of many of the non-latin character sets, as
demonstrated on the HELLO page (C-h h).

Note that you must run "fc-cache -fv" after installing this package to
rebuild your font cache, and Emacs won't pick it up until it is
restarted.

I haven't pushed this yet.  Comments and suggestions welcome.

      Mark
