Notable changes: * I am now using the same names for the fields of the language record and the instances in heap_lang. In order to deal with shadowing, I have put all definitions in heap_lang.v in a module. * Instead of defining evaluation contexts recursively, these are now defined using lists. This way we can easily reuse operations on lists. For example, composition of evaluation contexts is just appending lists. Also, it allowed me to simplify the rather complicated proof of step_by_val as induction on the shape of contexts no longer results in a blowup of the number of cases. * Use better automation to prove all lemmas of heap_lang. * I have introduced tactics to invert steps and to do steps. These tactics greatly helped simplifying boring parts of lifting lemmas.

This way we can more easily state lemmas for concrete languages for arbitrary global functors.

This enables us to remove a whole bunch of type annotations.

Instead, we have just a construction to create a CMRA from a RA. This construction is also slightly generalized, it now works for RAs over any timeless COFE instead of just the discrete COFE. Also: * Put tactics and big_ops for CMRAs in a separate file. * Valid is now a derived notion (as the limit of validN), so it does not have to be defined by hand for each CMRA. Todo: Make the constructions DRA > CMRA and RA > CMRA more uniform.
