Update to latest git snapshot for bug fixes.
Also:
- Add -doc subpackage.
- Add gecode 5 support, enabling gecode support for all releases.
- Add -python3 patch to adapt to python3.
- Jacop support did not work at all. Add Requires: jacop, symlink
to jacop.jar where mp expects to find it, and fix rpath handling
so libjvm.so can be found.
- Do not invoke rpm to get the jacop version; that is not guaranteed
to work.
- Build with openblas instead of atlas.
- Run all tests on Fedora and EPEL 7+.
- Numerous small spec file cleanups.
