Summary: tbv2: add dynamic context passed through all functions Previously for we had some shared state between all requests, noticeably the pointers set. This change adds a by reference value to all requests which can hold additional mutable state. The pointers set is moved into this mutable state for OIL, which means each concurrent request will have its own pointer set. Doing things this way allows more features to be added in the future without such a big code modification.
