Add support for curses color output over serial.
Note that the sequence \e[m for turning off bold resets all attributes, including color. Signed-off-by: Ulf Jordan <jordan@chalmers.se> Acked-by: Jordan Crouse <jordan.crouse@amd.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3561 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
