time. previous behavior (search ".rb", then ".so") has a
security risk (ruby-bugs#PR140).
* array.c (rb_ary_to_ary): new function to replace internal
rb_Array(), which never calls to_a, but to_ary (rb_Array() might
call both). [new]
* regex.c (PUSH_FAILURE_POINT): push option status again.
* regex.c (re_compile_pattern): avoid pushing unnecessary
option_set.
* eval.c (rb_load): tainted string is OK if wrapped *and*
$SAFE >= 4.
* eval.c (rb_thread_start_0): should not nail down higher blocks
before preserving original context (i.e. should not alter
original context).
* eval.c (proc_yield): new method equivalent to Proc#call but no
check for number of arguments. [new]
