* init.d-mandos (Required-Start, Required-Stop): Bug fix: Added
                 "$syslog", thanks to Petter Reinholdtsen
                 <pere@hungry.com> (Debian bug #546928).

* initramfs-tools-script: Removed erroneous comment.

* plugins.d/askpass-fifo.c: Removed TEMP_FAILURE_RETRY since it is
                            not needed.

* plugins.d/mandos-client.c (main): Bug fix: Initialize
                                    "old_sigterm_action".

* plugins.d/splashy.c (main): Bug fix: really check return value from
                              "sigaddset".  Fix some warnings on
                              64-bit systems.

* plugins.d/usplash.c (termination_handler, main): Save received
                                                   signal and
                                                   re-raise it on
                                                   exit.
  (usplash_write): Do not close FIFO, instead, take an additional file
                   descriptor pointer to it and open only when needed
                   (all callers changed).  Abort immediately on EINTR.
                   Bug fix:  Add NUL byte on single-word commands.
                   Ignore "interrupted_by_signal".
  (makeprompt, find_usplash): New; broken out from "main()".
  (find_usplash): Bug fix: close /proc/<pid>/cmdline FD on error.
  (main): Reorganized to jump to a new "failure" label on any error.
          Bug fix: check return values from sigaddset.
          New variable "usplash_accessed" to flag if usplash(8) needs
          to be killed and restarted.  Removed the "an_error_occured"
          variable.
