obsstore: also store the 'parents' field on disk
We now store the `parents` field on disk. We use the same strategy as for
`date`: We stick it into the metadata. This is slow and dirty, but this is also
the only way we currently have.
At some point we'll have a new obsstore format to store this properly.

The number of possible cases is significant but they all have a slighly different handling. So this section commits to generating and testing all of them to allow safe refactoring of the revert code. A python script is used to generate a file history for each combination of changes between, on one side the working directory and its parent and on the other side, changes between a revert target (--rev) and working directory parent. The three states generated are: - a "base" revision - a "parent" revision - the working directory (based on "parent") The file generated have names of the form: <changeset-state>_<working-copy-state> Here, "changeset-state" conveys the state in "base" and "parent" (or the change that happen between them), "working-copy-state" is self explanatory. All known states are not tested yet. See inline documentation for details. Special cases from merge and rename are not tested by this section. There are also multiple cases where the current revert implementation is known to slightly misbehave.
