Subject: * array.c (rb_ary_values_at): new method to replace select(index..).

* hash.c (rb_hash_values_at,env_values_at): ditto.

* re.c (match_values_at): ditto.

* struct.c (rb_struct_values_at): ditto.

* re.c (match_select): add iterator behavior.
	* ext/curses/curses.c, ext/digest/sha2/sha2.c, ext/iconv/iconv.c,
	  ext/racc/cparse/cparse.c: include "ruby.h" at the top to shut up
	  "_FILE_OFFSET_BITS redefined" warning on Solaris.

* class.c (rb_class_protected_instance_methods): now gives
  warnings to show migration path.  The default will be reversed
  on Jan 2004.

* numeric.c (num_step): "1.1.step(1.5,0.1)" to work.
