New changelog entries:
  * Stop upgrades purging walinuxagent meta-data and configuration files
    (LP: #1079897):
    - d/{control,walinuxagent-data-saver.preinst}: Added
      walinuxagent-data-saver package to ensure that agent generated data is
      not lost on upgrade by diverting /usr/sbin/waagent during the upgrade
      process.
    - d/walinuxagent-data-saver.lintian-overrides: Override errors about use
      of dpkg-divert in this package.
    - d/control: Added Pre-Depends to walinuxagent on walinuxagent-data-saver.
    - d/prerm: Stop calling waagent --uninstall during reconfiguration
      and upgrade, specify files to remove manually for purge.
    - d/postinst: Remove divert of /usr/sbin/waagent prior to completion of
      package install.
  * d/preinst: If upgrading from package version with unmanaged waagent upstart
    configuration stop the agent and remove the upstart configuration.
  * d/upstart: Tidied description in upstart job.
