Check for equality

<p>
This will only return true if the other object is a masked long, even if this one is
fully-defined, and the value is equal to a given long (or {@link Long}). The other masked
long must have the same mask and value to be considered equal. For other sorts of "equality"
checks, see {@link #agrees(Object)} and friends.
