* Merge from debian unstable. Remaining changes: - debian/rules: Switch back to using /usr/bin/gpg and add back gnupg build dependency, as we don't install gnupg2 by default. - debian/control: Depends on "gnupg | gnupg2" rather than gnupg2, default to the old version since the new one depends on gpg-agent, pinentry-gtk2, and a bunch of other packages we don't need/want in the default installation * Dropped changes: - debian/patches/CVE-2014-3564.patch: upstream - debian/patches/test_engine_ignore_filename.diff: upstream - debian/rules: Fix build failure by running the tests without parallelization: handled in Debian by using newer automake
