    Bit flags impacting revision behavior. The following bit offsets define:
    0: REVIDX_ISCENSORED revision has censor metadata, must be verified.
    1: REVIDX_EXTSTORED revision data is stored externally.

    Base or previous revision this revision's delta was produced against.
    -1 means this revision holds full text (as opposed to a delta).
    For generaldelta repos, this is the previous revision in the delta

    revision in the delta chain.

 20-23 (4 bytes)
    A revision this revision is *linked* to. This allows a revision in
    one revlog to be forever associated with a revision in another
    revlog. For example, a file's revlog may point to the changelog
    revision that introduced it.
