* pythonPackages.matplotlib: add veprbl to maintainers
* pythonPackages.matplotlib: remove an old darwin hack
* pythonPackages.matplotlib: remove python and stdenv from buildInputs
* python3Packages.matplotlib: remove a hack for python33
* pythonPackages.matplotlib: remove outdated checkPhase
Downloading the baseline_images is not a real issue, building against
older freetype (local_freetype = True) is, perhaps, not what we
want. The good news is that the tests would pass (tested on 3.2.1) if
we were to enable them:
========== 6684 passed, 1332 skipped, 10 xfailed in 228.64s (0:03:48) ==========
* pythonPackages.matplotlib: provide setup.cfg from a file instead of a patch
* python3Packages.matplotlib: 3.1.3 -> 3.2.1
Numpy deprecated asscalar in 1.16. This will be fixed in the next
matplotlib version, but to avoid deprecation warnings (and because they
are breaking the sage testsuite), it can't hurt to backport the fix
already.

We currently do not build mathplotlib with any backend. This can be very
confusing for users. They will try to use matplotlib and it will simply
display nothing (see #51337). We should ship at least one backend. `tk`
was chosen somewhat arbitrarily. The gtk backend is problematic (see
https://github.com/NixOS/nixpkgs/issues/50959#issuecomment-441327767)
so tkinter seems like a good choice.
There is already a backend provided on darwin so there is no reason to
include tk there.
