The goal of this PR is to bring down the TCB of our resource algebra formalization to what I believe is the smallest possible TCB that we can have given the absence of existentially quantified permissions in Gobra. Our assumptions are all listed in file `docs.gobra`, and only have to do with the introduction and elimination of existential quantifiers. There are a couple of todos here: - [ ] (maybe) clean up the code and use the implementations for MonoSet and MonoMap instead of the bespoke cooliomapio and cooliosetio :) - [x] Make `GlobalMem()` an invariant established during initialization and replace the `inhale`/`exhale` pairs with code to open the invariant. Done in #35, but it depends on viperproject/gobra#983. - [ ] Prove the last outstanding assumption: the product of all currently allocated elements for a reference is valid (might do this in a separate PR) (#36) PS: I introduced a new packet rather than changing package `resalgebra`, as the API for RAs changed slightly. I might deprecate `resalgebra` soon though
