sidedata: replace sidedata upgrade mechanism with the new one
Note: this is split into a separate change (like some other patches in this
series) because it's not easy to have all patches work 100% and this seemed
easier for reviewers.
When cloning or upgrading a repo, we may need to compute (or remove) sidedata.
This is the same mechanism that is used in exchange, so we re-use the new
system to simplify the code and fix the remaining issues (correctly dropping
flags and handling partial removal, etc.).
This also highlighted an issue with `test-copies-in-changeset.t` that kept
sidedata categories that are not relevant anymore. They should probably be
dropped entirely, but that would be for another patch.

'''http authentication with factotum This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide authentication information for HTTP access. Configuration entries specified in the auth section as well as authentication information provided in the repository URL are fully supported. If no prefix is specified, a value of "*" will be assumed. By default, keys are specified as:: proto=pass service=hg prefix=<prefix> user=<username> !password=<password> If the factotum extension is unable to read the required key, one will be requested interactively. A configuration section is available to customize runtime behavior. By default, these entries are:: [factotum] executable = /bin/auth/factotum mountpoint = /mnt/factotum service = hg The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path to the factotum file service. Lastly, the service entry controls the service name used when reading keys.
