Subject: * eval.c (rb_f_require): searches ".rb" and ".so" at the same   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]
