Diff to previous 32204

  Patch to correctly honour selector abort status settings in PROOF. Currently only
  the TSelector::kAbortProcess was handled by stopping processing. In particular
  TSelector::kAbortFile was ignored; this recently created some problems in ALICE
  with corrupted files, with repeated attempts to read events eventually leading to
  bad_alloc exceptions.

  This patch also fixes other related issues, in particular with the reporting of the
  non-processed {files, events} in the final 'MissingFiles' list. This list should
  now account much more precisely of the number of events which could not be processed.

  It also fixes a problem with the final update of the progress information affecting
  occasionally cases with skipped events.

   Add support for processing many datasets in one go in TProof::Process(const char *dataset, ...).
   Two options are provided:
   - 'grand dataset':  the datasets are added up and considered as a single dataset;
                       syntax: "dataset1|dataset2|..."
   - 'keep separated': the datasets are processed one after the other; the user is
                       notified in the selector of the change of dataset so she/he
                       has the opportunity to separate the results. A new packetizer,
                       TPacketizerMulti, has been developed for this case: it basically
                       contains a list of standard packetizers (one for each dataset) and
                       loops over them.
                       Syntax: "dataset1,dataset2,..." or dataset1 dataset2 ..."
   In both cases, entry-list can be applied using the syntax "dataset<<entrylist", e.g.
   "dataset1<<el1|dataset2<<el2|".
   See http://root.cern.ch/drupal/content/working-data-sets#currentelem for more details.

   A test for the new functionality has been added to test/stressProof.cxx .
