These patches are in the original upstream Debian package:

At least one of these is documented in the changelog already:

  * Fix implicit pointer conversion. (closes: #516867)

And some have likely been removed as documented in the new upstream

  * Don't longer build static libraries.

The remaining two from Ubuntu are documented in the changelog, and have
been forwarded to Debian:

    - add packages for upstream event manager (Debian bug 514706):
      - debian/patches/libdm-event-static.patch: force static library build.
      - debian/patches/rules-subdir.patch: update to reorder build targets.
