revlog-index: add `replace_sidedata_info` method...

revlog-index: add `replace_sidedata_info` method During a `pull` operation where the server does not provide sidedata, the client that requires it should generate them on-the-fly. In the generic case, we need to wait for the changelog + manifests + filelogs to be added, since we don't know what the sidedata computers might need: this means rewriting the sidedata of index entries from within the pull transaction (and no further back) right after we've added them. Both Python and C implementations only allow for rewriting the sidedata offset and length for revs within the transaction where they were created.
