Add dracut(8) support

Add support for the dracut(8) system for generating initramfs image

* .bzrignore (dracut-module/password-agent): Ignore new binary file.
* dracut-module: New directory for the dracut module.
* INSTALL (Prerequisites/Libraries/Mandos Client): Add dracut as an
                                                   alternative to
                                                   initramfs-tools,
                                                   and also add GLib.
* Makefile (DRACUTMODULE, GLIB_CFLAGS, GLIB_LIBS): New.
  (CPROGS): Add "dracut-module/password-agent".
  (DOCS): Add "dracut-module/password-agent.8mandos".
  (dracut-module/password-agent.8mandos): New.
  (dracut-module/password-agent.8mandos.xhtml): - '' -
  (dracut-module/password-agent): - '' -
  (check): Add command to run tests of password-agent(8mandos).
  (install-client-nokey): Also install the dracut module directory,
                          its files, and the password-agent(8mandos)
                          manual page.
  (install-client): To update the initramfs image file, run
                    update-initramfs or dracut depending on what is
                    installed.
  (uninstall-client): - '' - and also uninstall the the files in the
                      dracut module directory, that directory itself,
                      and the password-agent(8mandos) manual page.
* debian/control (Build-Depends): Add "libglib2.0-dev (>=2.40)".
  (Package: mandos-client/Depends): Add "dracut (>= 044+241-3)" as an
                                    alternative dependency to
                                    initramfs-tools.
  (Package: mandos-client/Conflicts): New; set to
                                      "dracut-config-generic".
  (debian/mandos-client.README.Debian): Document alternative commands
                                        to update the initramfs image
                                        for when dracut is used.
* debian/mandos-client.postinst (update_initramfs): Use alternative
                                                    commands to update
                                                    the initramfs
                                                    image for when
                                                    dracut is used.
* debian/tests/control (password-agent, password-agent-suid): Add two
                                                              new tests.
* dracut-module/ask-password-mandos.path: New.
* dracut-module/ask-password-mandos.service: - '' -
* dracut-module/cmdline-mandos.sh: - '' -
* dracut-module/module-setup.sh: - '' -
* dracut-module/password-agent.c: - '' -
* dracut-module/password-agent.xml: - '' -
* initramfs-unpack: Use the dracut "skipcpio" command, if available.
                    Also be more flexible and try hard to detect where
                    compressed data starts.
* plugins.d/mandos-client.xml (SECURITY): Be more precise that the
                                          mandos-client binary might
                                          not always be setuid, but
                                          that the program assumes
                                          that it has been started
                                          that way.
* plugins.d/password-prompt.c: Add new "--prompt" option.
  (conflict_detection): First try to detect the new PID file of
                        plymouth.
  (main): Define and use new "prompt" variable.
* plugins.d/password-prompt.xml (SYNOPSIS): Show new --prompt option.
  (DESCRIPTION): Describe new behavior of looking for plymouth PID
                 file.
  (OPTIONS): Document new "--prompt" option.
  (ENVIRONMENT): Clarify that the CRYPTTAB_SOURCE and CRYPTTAB_NAME
                 environment variables are not used if the --prompt
                 option is used.  Remove unnecessarily specific
                 details about where the CRYPTTAB_SOURCE and
                 CRYPTTAB_NAME comes from, since this can now be
                 either initramfs-tools or dracut.
  (SEE ALSO): Remove superfluous crypttab(5) reference, and add commas
              to separate the other references.
* plugins.d/plymouth.c: Add new "--prompt" and "--debug" options.
  (debug): New global flag.
  (fprintf_plus): New function, used for debug output.
  (exec_and_wait): Add extra "const" to "argv" argument.
  (main): Define and use new "prompt" variable.  Add debug output.
  (main/options, main/parse_opt): New; used to parse options.

  (OPTIONS): Document new options.
  (ENVIRONMENT): Clarify that the cryptsource and crypttarget
                 environment variables are not used if the --prompt
                 option is used.  Remove unnecessarily specific
                 details about where the cryptsource and crypttarget
                 comes from, since this can now be either
                 initramfs-tools or dracut.
  (EXAMPLE): Add an example using an option.
  (SEE ALSO): Remove superfluous crypttab(5) reference.
* plugins.d/splashy.xml (ENVIRONMENT): Clarify that the cryptsource
                                       and crypttarget environment
                                       variables are not used if the
                                       --prompt option is used.
                                       Remove unnecessarily specific
                                       details about where the
                                       cryptsource and crypttarget
                                       comes from, since this can now
                                       be either initramfs-tools or
                                       dracut.
  (SEE ALSO): Remove superfluous crypttab(5) reference.
