Subject: [PATCH 03/16] Release 5.5.18

This release introduces following features:

  - Addition of signal that caused crash and thread name to
    dbus signal (in sys.signal and sys.tid.comm fields, respectively)

    Additionally, report path is appended properly to the signal
    (bugfix)

  - Livecoredump reports are saved in livedump/ subdirectory
    from this release

  - Executable name is passed to minicoredumper allowing per-app
    recipes to be specified

  - All executables are rebuild as PIE as needed for ASLR to work

Subject: [PATCH 05/16] Lower the number (and priority) of crash-worker sysctl
 config file

Install sysctl file with 70 prefix instead of 99.  This will allow
overriding variables by creating eg. 99-local.conf file with appropriate
vars.
