Some specific tasks

1. ensure that "make doc" works : https://patchbot.sagemath.org/log/0/Ubuntu/18.04/x86_64/4.15.0-20-generic/petitbonum/2018-06-11%2009:26:28?plugin=docbuild

  1. update some packages

    1. update pynac : https://trac.sagemath.org/ticket/24838 ; https://trac.sagemath.org/ticket/24751 ; https://trac.sagemath.org/ticket/24752

    2. update sagenb : https://github.com/sagemath/sagenb/pull/446

    3. update brial : https://trac.sagemath.org/ticket/24786

  2. make all doctests pass

    1. fix doctests in plot/plot.py : https://trac.sagemath.org/ticket/25579/

    2. fix doctests in src/sage/combinat/root_systems/plot.py

    3. fix pickling : https://trac.sagemath.org/ticket/24582/

    4. fix all doctests of some touchstone files (for example src/sage/schemes/elliptic_curves/ell_rational_field.py)
    5. fix all doctests of some core files (for example src/sage/rings/integer_ring.pyx)

2. monitor the progress

  1. estimate how many files still have doctest failures
  2. tools to check for progress and prevent regression

  3. enhance the patchbot "pyflakes" plugin : https://github.com/sagemath/sage-patchbot/issues/128

  4. patchbot doctests on sage3 (HUGE) : https://patchbot.sagemath.org/log/0/Ubuntu/18.04/x86_64/4.15.0-20-generic/petitbonum/2018-06-15%2012:41:41?short
