[bug#56729] [RFC PATCH v2 00/29] Add sagemath.

[vicvbcun <guix@ikherbers.com>]

Hello guix!

This is a second try, hopefully this time without silly errors.

The packaging of sagemath is for now structured as follows:
- `sagemath-just-build' builds everything using the minimal set of
  dependecies to avoid rebuilding where possible. As runtime
  dependencies are missing, this is useless on its own.
- `sagemath-with-dependencies' adds all remaining dependencies as
  propagated-inputs. This should work, if we set a few additional
  environment variables.
- `sagemath-tests' simply runs the tests.

If I interpret the output correctly, these are the tests that are still
failing:

Some of these seem harmless, others seem more concerning (including
segmentation faults), some due to still missing dependencies.

Some Notes:
- We need to set some environment variables, so that sage can find all
  dependencies (see `sagemath-tests'). I suppose we could wrap the
  `sage' command, but this would of course add them as dependencies.

- For the `sagemath-data-*' packages, I couldn't find explicit Licenses.
  In Sage's COPYING.txt it just says "None (database)" for license.

- How should we handle test failures? Given errors such as the ones
  below, it seems delusional to expect every test to succeed.
>  Failed example:
>      solve_ineq_fourier([x+y<9,x-y>4],[y,x])
>  Expected:
>      [[y < min(x - 4, -x + 9)]]
>  Got:
>      [[y < min(-x + 9, x - 4)]]

>  Failed example:
>      FDS.basename
>  Expected:
>      'sage.rings.integer'
>  Got:
>      '/gnu/store/.../lib/python3.9/site-packages/sage/rings/integer.pyx'

- `python-cython' is build-time dependency but may be needed at runtime.
  This could cause issues when cross-compiling, right? I think its path
  is only in the wrappers in bin/*.
