http://bugs.debian.org/662175

* Upstream update

[ Jonas Smedegaard ]
* Drop local CDBS snippets: All included in main cdbs now.
* Use source format 3.0 (quilt), and stop including patchsys-quilt.mk.
  Stop build-depending on quilt, patchutils.
* Add full licensing header to debian/rules, and update copyright
  years.
* Add README.source (and drop outdated README.cdbs-tweaks).
* Refresh patches with shortening quilt options --no-index
  --no-timestamps -pab, and fix their path prefix.
* Rewrite copyright file using draft DEP-5 format.
* Update control file Vcs-* fields: Packaging moved to Git.
* Ease building with git-buildpackage:
  + Add gbp.conf, enabling pristine-tar and tag signing.
  + Git-ignore quilt .pc dir.
* Bump debhelper compat level to 7.
* Update Vcs-Browser field to use anonscm.debian.org.
* Add Giulio Paci and Jérémy Lal as uploaders, and permit Debian
  Maintainers to upload.

[ Jérémy Lal ]
* Drop patch 1002 to fix capitalized flag: corrected upstream.

[ Giulio Paci ]
* Restart package development.
  Closes: #662175.
* Add patches to fix compilation and documentation.
* Provide JIT flavor on supported architectures (i386 and amd64).
* Bump standards-version to 3.9.3.
* Update copyright file:
  + Adjust licenses now clarified/improved upstream.
* Update ChangeLog.cvs.
* Enable CDBS autogeneration of autotools files.
