unit: remove union Unit

Now that objects of all unit types are allocated the exact amount of
memory they need, the Unit union has lost its purpose. Remove it.

"Unit" is a more natural name for the base unit class than "Meta", so
rename Meta to Unit.

Access to members of the base class gets simplified.
