Jake Hillion b117150f83 tbv2: add dynamic context passed through all functions (#410)
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.
