This patch is a bit bigger than expected since Gentoo being
non-standard in some places.

 1. it is installing binaries at /usr/bin instead of /bin.

 2. it is using CamelCase names for consolefonts.

 3. /etc/rc.conf:unicode=(yes|no) just forbids loadkeys and setfont
    "-u" options, but do not disable the actual kernel default_utf8
    from vt module.
