revert: use modified information from both statuses

Using status information against the target ensures we are catching all

We still need to distinguish fresh modifications for backup purpose.

test-largefile is affected because it reverted a file that needs no content
change.

 More rebase testing, but also test that the largefiles are downloaded from
 'default-push' when no source is specified (issue3584). (The largefile from the
 pulled revision is however not downloaded but found in the local cache.)
 Largefiles are fetched for the new pulled revision, not for existing revisions,
 rebased or not.

 Systematic behavior validation of most possible cases
 =====================================================
 
 This section tests most of the possible combinations of working directory
 changes and inter-revision changes. 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
