This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.
This modifies some internal functions that took a safe level argument
to no longer take the argument.
rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.
One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd. We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.
* range.c (range_step, range_each): String#upto should never
modifies the receiver, use frozen strings to enumerate symbols.
* re.c (reg_operand): matching target is not modified.
* ext/socket/constants.c (constant_arg): str_to_int never modifies
argument strings.
