Clean up and ANSIfy unexcoff.c.

 unexcoff.c (report_error, make_hdr, write_segment)
 (copy_text_and_data, copy_sym, mark_x, adjust_lnnoptrs, unexec):
 Convert argument lists and prototypes to ANSI C.
 (make_hdr, write_segment): Remove unused variables.
 (unexec): Remove commented-out line.  Initialize `new' to shut up
 compiler warnings.

 +      Simplify termio code.
 +      All non-MSDOS non-WINDOWSNT platforms define HAVE_TERMIOS, so
 +      HAVE_TERMIO code is obsolete.
 +      Replace HAVE_TERMIOS conditionals with !DOS_NT.
 +      * systty.h: Do not define HAVE_TCATTR.
 +      Remove HAVE_TERMIO, HAVE_LTCHARS and HAVE_TCHARS code.
 +      Do not define EMACS_HAVE_TTY_PGRP.  Only define
 +      EMACS_GET_TTY_PGRP for !DOS_NT.
 +      * sysdep.c: Include sysselect.h unconditionally.  Do not include
 +      sys/ioctl.h and termios.h, systty.h does it.  Use
 +      HAVE_SYS_UTSNAME_H instead of USG as an include guard.
 +      (init_baud_rate): Remove HAVE_TERMIO code.
 +      (child_setup_tty): Remove HAVE_TERMIO code.
 +      (emacs_get_tty, emacs_set_tty): Remove HAVE_TERMIO, HAVE_TCHARS
 +      and HAVE_LTCHARS code.  Use !DOS_NT instead of HAVE_TCATTR.
 +      (new_ltchars, new_tchars): Remove, unused.
 +      (init_sys_modes): Remove HAVE_TERMIO, HAVE_TCHARS and HAVE_LTCHARS
 +      code.  Remove special casing for __mips__, it was a no-op.  Remove
 +      HAVE_TCATTR conditional, it is implied by HAVE_TERMIOS.
 +      (init_sys_modes): Remove HPUX special case.
 +      * process.c: Include stdlib.h unconditionally.  Do not include
 +      fcntl.h, systty.h does it.  Remove conditional code for
 +      HAVE_SERIAL, it is always true.
 +      (process_send_signal): Remove HAVE_TERMIOS conditional, it's
 +      always true when SIGNALS_VIA_CHARACTERS is true.
 +      (Fcontinue_process, Fprocess_send_eof): Simplify conditionals:
 +      !WINDOWSNT means HAVE_TERMIOS.
 +      (create_process): Remove HAVE_TERMIOS, it's inside a HAVE_PTYS
 +      conditional, which is true for all HAVE_TERMIOS systems.
 +      * keyboard.c (init_keyboard): Do not use HAVE_TERMIO, use !DOS_NT
 +      instead of HAVE_TERMIOS.
 +      * emacs.c (shut_down_emacs): Use !defined DOS_NT instead of
 +      EMACS_HAVE_TTY_PGRP.
 +      * callproc.c (child_setup): Move EMACS_SET_TTY_PGRP use to the
 +      non-MSDOS, non-WINDOWSNT code, it's only defined for such systems
 +      anyway.

        * dispnew.c (buffer_posn_from_coords): Fix off-by-one error in
