`abstract` attribute should be disallowed in `interface`s in any way as it does
nothing except confuses people.

This code should NOT compile:
---
interface I
{
    abstract void f();      // should be error
    abstract { void g(); }  // should be error
    abstract: void h();     // should be error
}
---
