This patch enables building .pdf documentation using new 'pdf-docs'
tox environment. The newly created tox environment creates latex
source codes using sphinx-build and then builds the pdf
documentation using make.
Also, convert README.md to README.rst for more seamless integration
of the README file in the pdf and html documentation.

Suppress the E006 warnings since we don't enforce
