Merge branch 'ks/combine-diff'

Browse Source 
Teach combine-diff to honour the path-output-order imposed by
diffcore-order, and optimize how matching paths are found in
the N-way diffs made with parents.

* ks/combine-diff:
  tests: add checking that combine-diff emits only correct paths
  combine-diff: simplify intersect_paths() further
  combine-diff: combine_diff_path.len is not needed anymore
  combine-diff: optimize combine_diff_path sets intersection
  diff test: add tests for combine-diff with orderfile
  diffcore-order: export generic ordering interface
