This is all going to be transparent to everyone. We've already split
out Acquisition, ExtensionClass (ComputedAttribute, MethodObject) in
the same way.

Note that the packages I'm proposing to split out have no Python fallback.

The C code which we might want to turn into optional optimizations at
a later point, would follow the same standard we already use in the
Zope Toolkit. So there won't be any new kind of risk. For example
zope.i18nmessageid and zope.interface use this approach.
