Summary: In the current state of things, the deallocation path puts a chunk in the Quarantine whether it's enabled or not (size of 0). When the Quarantine is disabled, this results in the header being loaded (and checked) twice, and stored (and checksummed) once, in `deallocate` and `Recycle`. This change introduces a `quarantineOrDeallocateChunk` function that has a fast path to deallocation if the Quarantine is disabled. Even though this is not the preferred configuration security-wise, this change saves a sizeable amount of processing for that particular situation (which could be adopted by low memory devices). Additionally this simplifies a bit `deallocate` and `reallocate`.
