Sync liblinear 1.8+dfsg-2 (main) from Debian unstable (main)

Please sync liblinear 1.8+dfsg-2 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
  * debian/control:
    - Use dh_python2 instead of python-support
    - Add X-Python-Version
    - Drop libsvm-tools from Recommends to Suggests, as the tools are only
    mentioned in man pages.
  * debian/pyversions:
    - Drop, unused with dh_python2
Fixed in debian

Changelog entries since current utopic version 1.8+dfsg-1ubuntu1:

liblinear (1.8+dfsg-2) unstable; urgency=low

  * debian/control:
    - Demoted liblinear1's Recommends for liblinear-tools to Suggests, so
      packages depending only on the library don't pull in the tools.
      Closes: #682062
    - Demoted liblinear-tools' Recommends for libsvm-tools to Suggests, for the
      same reasons. Closes: #679992
    - Bumped Standards-Version to 3.9.5 (no changes needed)
    - Bumped debhelper compatibility version to recommended level 9
    - Dropped dependency on python-support, and added a dependency on
      python-all-dev (>= 2.6.6-3~) for dh_python2, as well as added
      X-Python-Version >= 2.5. Closes: #679993
    - Updated BLAS dependency to libblas-dev | libblas.so, the currently
      recommended approach.
  * debian/compat:
    - Raised debhelper compatibility level to recommended level 9
  * debian/rules:
    - Converted to dh_python2
    - Fixed get-orig-rules target in debian/rules. The generated tarball did
      not match the git version
    - Use DEB_CFLAGS_MAINT_APPEND, as recommended, instead of CFLAGS
  * debian/copyright:
    - Updated to machine-readable copyright format 1.0
  * debian/gbp.conf
    - Created (package is based on dfsg branch, not upstream)
  * debian/patches (new):
     - 0006-Improve-option-parsing
       Use optarg, avoid atoi, verify argument count. Closes: #716115
  * debian/patches (modified):
    - 0001-Properly-build-shared-and-static-libraries-programs
      Include CPPFLAGS to avoid hardening flag warnings
  * debian/source/lintian-overrides:
    - Added override for debian-watch-may-check-gpg-signature
  * debian/*.lintian-overrides:
    - Added overrides for no-upstream-changelog
