configure.ac:  use new Autoconf 2.70 syntax for AC_PROG_LEX

Use 'noyywrap' for AC_PROG_LEX.
Use AC_CONFIG_HEADERS instead of obsolete AC_CONFIG_HEADER.

>From Autoconf 2.70 documentation:
  AC_PROG_LEX now takes one argument, which may be either 'yywrap' or
  'noyywrap'.  If it is 'noyywrap', AC_PROG_LEX will only set LEXLIB
  to '-lfl' or '-ll' if a scanner that defines both main and yywrap
  itself still needs something else from that library.  On the other
  hand, if it is 'yywrap', AC_PROG_LEX will fail (setting LEX to ':'
  and LEXLIB to nothing) if it can't find a library that defines yywrap.

  In the absence of arguments, AC_PROG_LEX's behavior is bug-compatible
  with 2.69, which did neither of the above things.  This mode is
  deprecated.

  Prior to Autoconf 2.70, AC_PROG_LEX did not take any arguments,
  and its behavior was different from either of the above
  possibilities: it would search for a library that defines 'yywrap',
  and would set 'LEXLIB' to that library if it finds one.  However,
  if a library that defines this function could not be found,
  'LEXLIB' would be left empty and 'LEX' would _not_ be reset.  This
  behavior was due to a bug.
