* Remove generic path_typed instance for lists. For the zippers in the operational semantics, it goes the other way around. * Remove constructor lemmas for values/memory_trees and use a generic tactic instead. This tactic uses the standard constructor tactic, but folds the type classes afterward.

Major changes: * A data structure to collect locked addresses in memory. * Operations to lock and unlock addresses. * Remove [ctree_Forall] and express it using [Forall] and [ctree_flatten]. This saves a lot of lines of code. * Add a [void] value. This value cannot be typed, but will be used as a dummy return value for functions with return type [void]. Minor changes: * Various deciders in preparation of the executable semantics. * Improve naming and notations. * Remove obsolete stuff.

* Parametrize refinements with memories. This way, refinements imply typing, for example [w1 ⊑{Γ,f@m1↦m2} w2 : τ → (Γ,m1) ⊢ w1 : τ]. This relieves us from various hacks. * Use addresses instead of index/references pairs for lookup and alter operations on memories. * Prove various disjointness properties.

The refactoring includes: * Use infix notations for the various list relations * More consistent naming * Put lemmas on one line whenever possible * Change proofs into one-liners when possible * Make better use of the "Implicit Types" command * Improve the order of the list module by placing all definitions at the start, then the proofs, and finally the tactics. Besides, there is some new machinery for proofs by reflection on lists. It is used for a decision procedure for permutations and list containment.

Both the operational and axiomatic semantics are extended with sequence points and a permission system based on fractional permissions. In order to achieve this, the memory model has been completely revised, and is now built on top of an abstract interface for permissions. Apart from these changed, the library on lists and sets has been heavily extended, and minor changed have been made to other parts of the prelude.
