Added many patches from current upstream
    
    to fix mainly:
      - Loss of ordering with restart jobs and the behavior of try-restart while
        the service is inactive with a pending job (#753586).
      - Assertion in systemd-analyze while boot is still in progress (#701669).
      - systemd-tmpfiles preservation of atime on subdirectories (#810257).
      - Requires= dependencies were not started by systemctl restart (#802770).
    - As a dependency for #753586, a refactoring of the transaction code is
      included. It also fixes several bugs.
    - A few low-risk or cosmetic fixes are included too.
    
    Notably skipped were the patches that improve systemd behavior in containers.
    They were not considered important for F16.
