Warn on access/modify of $SAFE, and remove effects of modifying $SAFE
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.
