There was not really a need for the lattice type classes, so I removed these.

The singleton maps notation is now also more consistent with the insert <[_ := _]> _ notation for maps.

Important changes in the core semantics: * Types extended with function types. Since function types are a special kind of pointer types, types now have an additional mutual part called "ptr_type". * Pointers extended with function pointers. Theses are just names that refer to an actual function in the function environment. * Typing environments extended to assign argument and return types to function names. Before we used a separate environment for these, but since the argument and return types are already needed to type function pointers, this environment would appear in pretty much every typing judgment. As a sideeffect, the frontend has been rewritten entirely. The important changes are: * Type checking of expressions is more involved: there is a special kind of expression type corresponding to a function designator. * To handle things like block scoped extern function, more statefullness was needed. To prepare for future extensions, the entire frontend now uses a state monad.

Integers with the same size, are no longer supposed to have the same rank. As a result, the C integer types (char, short, int, long, long long) are different (and thus cannot alias) even if they have the same size. We now have to use a more involved definition of integer promotions and usual arithmetic conversions. However, this new definition follows the C standard literally.

The proof now uses the stronger notion of memory permutation instead of a more general memory refinement. We have also proven that memory permutations are symmetric.
