Log Message:
wscons(4): Add support for 256 colours to VT100 emulation

Also implemented are CSI 90-97 and CSI 100-107 to set the bright
versions of the regular eight colours directly.

wscons already has full support of 8/16/24/32-bit displays (and
can take advantage of them for antialiased fonts), but increasingly
command-line applications are built to take advantage of colours beyond
the standard 8 provided by the ANSI escape codes. These extensions are
not generally standardized, but xterm serves as a de-facto standard.

Patch from Crystal Kolipe, adjusted slightly to work on 16-bit and
24-bit displays by me.
