summary:

bpo-35293: Travis CI uses "make venv" for the doc (GH-22307)

Doc/requirements.txt becomes the reference for packages and package
versions needed to build the Python documentation.

* Doc/Makefile now uses Doc/requirements.txt
* .travis.yml now uses "make env" of Doc/Makefile

files:
M .travis.yml
M Doc/Makefile
M Doc/requirements.txt
