Qualifier no longer defers "(nested) class vs package" resolution.

Consider FQN 'a.b.c'.
If 'a' is a classifier in the current scope,
    resolve rest in the corresponding class scope.
Otherwise (if 'a' is a package),
    find the maximum possible prefix 'a.b' resolving to a package,
    resolve rest in the corresponding package scope.
