Add the in* and out* functions for i386. Note: the sys/io.h header for
glibc-2.2.2 actually defines static inline versions for i386, but only
provides prototypes for externs for the other archs I looked at. Since
uClibc shares this header amongst archs, I stashed the inline defs in
bits/io_i386.h and included it when __i386__ was defined. Better solutions
are most welcome, but it doesn't clutter sys/io.h too badly and now lilo
and the pcmcia tools build against uClibc on i386 without modification.
