Subject: [PATCH] Restore LongHashFunction.xx_r39() to allow consumers to
 migrate to xx()

Add alias to LongHashFunction.xx() called LongHashFunction.xx_r39() to allow
consumers to migrate code from xx_r39() to xx() without breaking at runtime.

The LongHashFunction.xx_r39() method delegates to LongHashFunction.xx() so it
is identical in behavior. It's marked as deprecated.
