rust-utils: use new find_dirs iterator In cad3dde7a573, the `find_dirs` util was introduced, but the second changeset that made use of it didn't apply. This change fixes the issue. Differential Revision: https://phab.mercurial-scm.org/D6639

copies: remove unnecessary override of p[12]copies() in workingctx The implementation is identical to the version inherited from basectx. Differential Revision: https://phab.mercurial-scm.org/D6647

tests: properly position conditional output on Windows in test-subrepo.t The test runner doesn't always guess the right location when optional output is missing. This goes with f6540aba8e3e. Differential Revision: https://phab.mercurial-scm.org/D6640

abort: removed labels argument from abortmerge() Labels are used to label the code that belongs to `working copy` and `merge rev` in case of a conflicted state. No such labelling is required while aborting merge as conflicted parts are reverted to normal. Differential Revision: https://phab.mercurial-scm.org/D6638

py3: source-transform only call-sites of iteritems(), not definitions branchmap.branchcache, among other classes, defines a iteritems(). That currently gets replaced by items() by the source transformer. That makes it harder for extensions to work with both py2 and py3, since they have to call either items() or iteritems() on branchcache. Let's not replace definitions of iteritems() (and itervalues()) and only replace the call-sites. We need to also add an items() alias to branchcache (etc) so our transformer call-sites will find it.
