sidedatacopies: write copies information in sidedata when applicable

If the format of the repository indicate it stores copies information into
changeset's sidedata, then we actually write that information into sidedata at
commit time. It will be put to use in later changesets.

Currently, we store all field unconditionally, but that is likely to change in
the future for the sake of efficiency.
