Bug#683073: unblock: gnunet/0.9.3-3

[Bertrand Marc <beberking@gmail.com>]

Dear release team,

I prepared a new revision of gnunet, fixing a grave bug (#670578), 
thanks to Gregor Herrmann. Here is the new changelog:
  * debian/control: update Vcs-* to the new repository in collab-maint.
  * Install only the generated binaries on Hurd, thanks to Cyril Roelandt
    (Closes: #670794).
  * Use chmod and chown instead of dpkg-statoverride to set special 
permissions
    and upgrade properly depending on the previous version (Closes: 
#673301).
  * Rewrite gnunet-server.init based on /etc/init.d/skeleton and make
    gnunet-server depend on lsb-base to use LSB logging.
  * Fix "gcc-4.6: [sparc] compiler fails to align stack-allocated
    struct, with array of uint32-values to 32-bit boundary":
    new patch sparc_alignment.patch, taken from upstream:
    https://lists.gnu.org/archive/html/gnunet-svn/2012-07/msg00548.html
    Thanks to Jurij Smakov for the analysis.
    (Closes: #670578)
