doc: make the RST files consistently formated and other improvements.

The biggest things here are:
 * move doc/sources/*/README.rst to doc/rtd/topics/datasources
   This gives each datasource a page in the rtd docs, which make
   it easier to read.
 * consistently use the same header style throughout.
   As suggested at
   http://thomas-cokelaer.info/tutorials/sphinx/rest_syntax.html
   use:
     # with overline, for parts
     * with overline, for chapters
     =, for sections
     -, for subsections
     ^, for subsubsections
     “, for paragraphs

Also, move and re-format vendor-data documentation to rtd.
