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_scrollok): use RTEST().
* 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.

POSIX_SIGNAL is defined.
* eval.c (error_print): errat array may be empty.
* eval.c (rb_eval_cmd): should not upgrade safe level unless
explicitly specified by argument newly added.
* signal.c (sig_trap): should not allow tainted trap closure.
* variable.c (rb_f_trace_var): should not allow trace_var on safe
level higher than 3.
* variable.c (rb_f_trace_var): should not allow tainted trace
closure.
* gc.c: do not use static stack until system stack overflows.
* eval.c (eval): should call Exception#exception instead of
calling rb_exc_new3() directly.
* error.c (exc_exception): set "mesg" directly to the clone. it
might be better to set mesg via some method for flexibility.
* variable.c (cvar_override_check): should print original module
name, if 'a' is T_ICLASS.
* parse.y (yylex): float '1_.0' should not be allowed.
* variable.c (var_getter): should care about var as Qfalse
(ruby-bugs#PR199).
* array.c (cmpint): <=> or block for {min,max} may return bignum.
* array.c (sort_1): use rb_compint.
* array.c (sort_2): ditto.
* enum.c (min_ii): ditto.
* enum.c (min_ii): ditto.
* enum.c (max_i): ditto.
* enum.c (max_ii): ditto.

should remain anonymous.
* eval.c (rb_call0): self in a block given to define_method now be
switched to the receiver of the method.
* eval.c (proc_invoke): added new parameter to allow self
switching.

to mvalue. [experimental]
* eval.c (mvalue_to_svalue): new function to convert from mvalue
to svalue.
* eval.c (rb_eval): use mvalue_to_svalue().
* eval.c (rb_yield_0): use mvalue_to_svalue().
* eval.c (proc_invoke): proper mvalue handling.

stack bottom line.
* st.c (numhash): should shuffle bits by dividing by prime number.
* eval.c (rb_eval): multiple assignment behavior fixed, which
results "*a = nil" makes "a == []" now.
* eval.c (rb_f_require): should set SCOPE_PUBLIC before calling
dln_load().
