Remove unused and unsupported code. Consult the file
`DEVELOPMENT' for details. Partly based on suggestions by
Gianluca Guida <glguida@gmail.com>.
* i386/bogus/at3c501.h: Remove file.
* i386/i386at/if_3c501.c: Likewise.
* i386/i386at/if_3c501.h: Likewise.
* i386/i386at/autoconf.c: Don't include <at3c501.h> anymore and adopt
all users of NAT3C501 as if it were always defined to `0'.
* i386/i386at/conf.c: Likewise.
