CI fixes (#1744)

* Fix warning that not including a cmake source or build dir will be a fatal error (it is now on newest CMakes) * Fixes appveyor * Travis uses CMake 3.9 for more than a year now * Travis dropped sudo: false in December * Dropping Sphinx 2 - clang7: Suppress self-assign warnings; fix missing virtual dtors - pypy: - Keep old version (newer stuff breaks) - Pin packages to extra index for speed - travis: - Make docker explicit; remove docker if not needed - Make commands more verbose (for debugging / repro) - Make Ubuntu dist explicit per job - Fix Windows - Add names to travis
