revlog: introduce a `sidedata` method
The method give access to extra information related to the revision. Such data
will not be part of the hash be strongly related to the revision. Having them
stored at the revlog level helps the storage consistency story and simplify
various things.
Example of data we could store there:
- copy tracing related informations
- graph structure related information (useful for discovery)
- unresolved conflict data
The full implementation will be introduced gradually in the coming changesets.
