--- | Encapsulates a common pattern of operation between hashing and HMAC
--- computation. Both of these operations require an allocated context local to
--- the operation. The context gets initialized once, updated repeatedly, and
--- then finalized. Finally, we read the result out of a buffer produced by the
--- finalizer.
---
--- The updater must not mutate any argument other than the context.
---
--- If all arguments are safe to use under 'unsafeLocalState', this whole
--- function is safe to use under 'unsafeLocalState'.
