modifying buffer is shared.
* array.c (ary_make_shared): make an internal buffer of an array
to be shared.
* array.c (rb_ary_shift): avoid sliding an internal buffer by
using shared buffer.
* array.c (rb_ary_subseq): avoid copying the buffer.
* parse.y (gettable): should freeze __LINE__ string.
* io.c (rb_io_puts): old behavoir restored. rationale: a) if you
want to call to_s for arrays, you can just call print a, "\n".
b) to_s wastes memory if array (and sum of its contents) is
huge. c) now any object that has to_ary is treated as an array,
using rb_check_convert_type().
* hash.c (rb_hash_initialize): now accepts a block to calculate
the default value. [new]
* hash.c (rb_hash_aref): call "default" method to get the value
corrensponding to the non existing key.
* hash.c (rb_hash_default): get the default value based on the
block given to 'new'. Now it takes an optinal "key" argument.
"default" became the method to get the value for non existing
key. Users may override "default" method to change the hash
behavior.
* hash.c (rb_hash_set_default): clear the flag if a block is given
to 'new'
* object.c (Init_Object): undef Data.allocate, left Data.new.

* ext/curses/curses.c (window_idlok): ditto.
* ext/curses/curses.c (window_keypad): ditto.
* ext/curses/curses.c (window_idlok): idlok() may return void on
some platforms; so don't use return value.
* ext/curses/curses.c (window_scrollok): ditto for consistency.
* ext/curses/curses.c: replace FIX2INT() by typechecking NUM2INT().
* parse.y (str_extend): should not process immature #$x and
#@x interpolation, e.g #@#@ etc.
* enum.c (enum_sort_by): sort_by does not have to be stable always.
* enum.c (enum_sort_by): call qsort directly to gain performance.
* util.c (ruby_qsort): ruby_qsort(qs6) is now native thread safe.
* error.c (rb_sys_fail): it must be a bug if it's called when
errno == 0.
* regex.c (WC2MBC1ST): should not pass through > 0x80 number in UTF-8.

* gc.c (rb_gc_mark): ditto.
* gc.c (rb_gc): ditto.
* enum.c (sort_by_i): slight performance boost.
* gc.c (gc_mark_rest): should call gc_mark_children(), not gc_mark().

name, if 'a' is T_ICLASS.

oklass if oklass is a Module.
* hash.c (rb_hash_equal): check identiry equality first.

is permitted.

to break.

stable sort.

classes/modules.

* eval.c (ruby_finalize): should enclosed by PUSH_TAG/POP_TAG.

marked. it may contain non object pointer.

function.
