* hash.c (env_clear): new Hash compatible method.
* hash.c (env_shift): ditto.
* hash.c (env_invert): ditto.
* hash.c (env_replace): ditto.
* hash.c (env_update): ditto.
* array.c (rb_ary_join): dispatch based on "to_str".
* array.c (rb_ary_times): ditto.
* array.c (rb_ary_equal): ditto.
* process.c (rb_f_exec): dispatch based on "to_ary".
* eval.c (umethod_bind): exact class match is not required. relax
the restriction to subclasses.
* eval.c (rb_eval): call "inherited" before executing class body.
* class.c (rb_define_class): call "inherited" after defining the
constant.
* class.c (rb_define_class_under): ditto.
* eval.c (massign): expand first element if RHS is an array and
its size is 1, and LHS has concrete assignment target (i.e. LHS
has target(s) other than *var).
* eval.c (massign): avoid unnecessary avalue/svalue conversion.
* eval.c (rb_yield_0): ditto
* array.c (rb_ary_update): do not allocate unused array if rpl is
nil (i.e. merely removing elements).
* io.c (io_read): should resize supplied string if it's shorter
than expected.
