Remove unused and unsupported code. Consult the file `DEVELOPMENT' for details. Partly based on suggestions by Gianluca Guida <glguida@gmail.com>. * i386/bogus/blit.h: Remove file. * i386/i386at/blit.c: Likewise. * i386/i386at/blitreg.h: Likewise. * i386/i386at/blituser.h: Likewise. * i386/i386at/blitvar.h: Likewise. * i386/i386at/conf.c: Don't include <blit.h> anymore and adopt all users of NBLIT as if it were always defined to `0'. * i386/i386at/kd.c: Likewise. (blit_init): Remove definition. (blit_present): Likewise and adopt all users as if it were always defined to `FALSE'. * i386/Makefile.in (i386at-files): Remove `blit.c'.
