* ser-termios.c, ser-go32.c: Remove DEFUN crap, clean up.

* serial.h (EXFUN):  Remove all uses, convert to PARAMS.
* config/sun4os4.mh:  Include ser-termios.o.  FIXME, all .mh files
should include a ser-XXX.o module.

* dbxread.c (elfstab_build_psymtabs):  Remove DEFUN crap.
* defs.h, i960-pinsn.c, remote-hms.c:  Replace CONST with simple const.

* configure.in:  Map unrecognized sun 68k's, sun sparcs, into
known suns in configure.in, rather than mapping them to unique
config files that happen to duplicate other config files.
* config/sun3.{mh,mt}:  Remove (use identical sun3os4.*).
* config/sun4.{mh,mt}:  Remove (use identical sun4os4.*).
