telnetd.c (main):
telnetd-ktd.c (main): POSIX states that getopt returns -1 when it
	is done parsing options, not EOF.

configure.in: Rename HAS_* to HAVE_* for the following tests: sac.h,
	sys/ptyvar.h, sys/filio.h, sys/stream.h, gettosbyname(), and make
	appropriate adjustments in the rest of the .c files.  Remove tests
	which aren't being used anymore: vhangup, utmpx.h, utmp.h, etc.

defs.h: Use HAVE_SYS_FILIO_H instead of FILIO_H

sys_term.c: Use HAVE_SAC_H and HAVE_SYS_STREAM_H instead of
      HAS_SAC and STREAMS.

telnetd.c, telnetd-ktd.c: Use HAVE_GETTOSBYNAME instead of
      HAS_GETTOS

telnetd.c: Use HAVE_SYS_PTYVAR_H instead of HAS_PTYVAR.
