* io.c (rb_io_popen): accept integer flags as mode.

* file.c (rb_find_file_ext): extension table can be supplied from
  outside.  renamed.

* eval.c (rb_f_require): replace rb_find_file_noext by
  rb_find_file_ext.

* eval.c (rb_provided): should also check feature without
  extension.

* numeric.c (flo_to_s): do not rely on decimal point to be '.'

* parse.y (yylex): ternary ? can be followed by newline.
