GTID looses all binlog state after crash if InnoDB is disabled

          Description

          If InnoDB is disabled (and no other XA-capable engine is enabled), then the
          server does not do any binlog crash recovery during restart after a crash.

          This is not sufficient for GTID, as we need to recover the last GTID logged
          into the binlog (so that we can know the next seq_no to assign to new GTIDs
          and how to reply to connecting slaves etc.).

          Thus, even in non-XA case we still need to scan the binlog and do crash
          recovery, though the XA part of it can be ignored.

          Same when using using_heuristic_recover().

          (MyISAM of course is not crash safe, but it is still better to loose a few
          seconds of state or whatever compared to all state since prior server start).

                The patch ensures that we run a limited version of binlog recovery after a
                crash, even if we do not have any XA storage engine, so that the binlog state
                is recovered correctly.
