Don't set the autocr flag on the serial console; clean up crapsyslinux-3.81-pre12

libutil would set the autocr flag on the serial console, which really
never was any point -- we already do \n -> \r\n conversion explicitly
in the serial code.  This was always very annoying to deal with if the
menu was interrupted.

Furthermore, drop completely unnecessary
initialization/deinitialization routines that completely duplicated
other code.
