doc: initial sphinx-based documentation support
The release-notes script now produces Markdown compatible with
pandoc to help convert it into RST for sphinx.
Actual documentation is fairly limited currently.
We use intersphinx to link to various sub-projects' docs.
A .travis.yml file is added to build+publish documentation
when new code is pushed to github.
