branchcache: move the processing of the new data in a dedicated method
In a future changeset, this will allow the V3 of the branch cache to use a fast
path when possible.
================================================================
test the interaction of the branch cache with obsolete changeset
================================================================
Some corner case have been covered by unrelated test (like rebase ones) this
file meant to gather explicite testing of those.
