Previously, we violated that assumption is we too the deep capture set of a capture reference wiht singleton type.
Count in dcs exactly those locations where a cap gets replaced by a reach capability.
Simplify code that handles applications, avoiding adding pieces of mutable state.
The correct point to address charging reach capabilities is in markFree itself: When a reach capability goes out of scope, and that capability is not a parameter, we need to continue with the underlying capture set.

Also, several refactorings and fixes to the way we handle applications and markFree. This PR reflects the state of how we can improve the capture checker with fixes and simplifications without changing anything fundamental in the policies.
