Changes:

- Improve the -ecm patch.
- Add -formatargspec patch to silence doc-building warnings.
- Add -data-elliptic_curves_large subpackage.
- Build with bliss, coxeter3, and mcqd support.
- Fix typo that made the singular.hlp file inaccessible.
- Add more gap packages to get closer to the set shipped by upstream.
- Refactor Requires so they apply to the correct subpackages.
- More python 3 patching due to changes in python 3.8.
- Use upstream's method of installing jupyter support.
- Obsolete the sagemath-notebook-export subpackage.
