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.
