Enable OpenJDK update through uscan

[Tiago Stürmer Daitx]

In order to make OpenJDK 7 updates easier uscan/watch file should be enabled.

The OpenJDK 7 package is comprised of tarballs for IcedTea, JamVM, IcedTea sound, and OpenJDK modules (the OpenJDK "root", corba, hotspot, jaxp, jaxws, jdk, and langtools).

Both IcedTea and IcedTea-sound provide a PGP signature while the tarballs for OpenJDK modules and JamVM do NOT provide a PGP signature upstream.

Fortunately - IcedTea can do a sha256 checksum on both OpenJDK modules and JamVM tarballs if they are kept pristine. Additionally the OpenJDK modules would have to be uncompressed in a specific tree format, which is not supported by MUT. Given those restrictions it is better to pack these pristine tarballs inside their own orig tarball.

The proposed format is:
- keep the icedtea tarball pristine as the orig tarball file.
- keep the icedtea-sound tarball pristine as the "orig-icedtea-sound" module tarball.
- use a script (debian/repack) to download the OpenJDK modules + JamVM and put their tarballs under a single "orig-drops" module tarball.

    - S8172299: Improve class processing.
  * debian/compat: updated from 5 to 9.
  * debian/watch: using watch version 4 to download both icedtea and
    icedtea-sound. LP: #1642420.
  * debian/repack: simplified tarball download.
  * debian/rules:
    - removed 8u121 patches as they have been applied to 7u131.
    - building icedtea-sound on build/ directory
    - replaced 'dh_strip -k' calls by dh_prep
    - have the 'build' rule depend on 'debian/control' rule to force
      failure if debian/control gets regenerated.
    - added file 'security/blacklisted.cert' to be copied to etc dir
      (introduced by S8011402).
    - simplified build dependencies.
    - removed jtreg's xvfb-run call since icedtea takes care of calling it.
    - removed window manager as there are no additional significant failures
      on the jdk tests when not running one.
    - re-enabled jdk jtreg tests.
    - removed lpia arch.
    - use fonts-wqy-microhei and fonts-wqy-zenhei instead of transitional
      package names.
    - drop Recommends on obsolete GNOME libraries so they are not in a
      default GNOME desktop installation (Simon McVittie). Closes: #850270.
      + sun.net.spi.DefaultProxySelector prefers libglib2.0-0 (>= 2.24)
        over obsolete libgconf2-4.
      + sun.nio.fs.GnomeFileTypeDetector prefers libglib2.0-0 (>= 2.24)
        over libgnomevfs-2-0.
      + sun.xawt.awt_Desktop prefers libgtk2.0-0 (>= 2.14) over
        libgnomevfs2-0.
  * debian/control.in: added static build dependencies as their previous
    selection logic in debian/rules is no longer required.
  * debian/control: regenerated.
  * debian/patches/icedtea-sound.diff: removed, now packing icedtea-sound
    1.0.1 which includes those fixes.
  * debian/upstream/signing-key.asc: add new signing key.
