Cleanup: move public doc-strings into headers for various API's

Some doc-strings were skipped because of blank-lines between
the doc-string and the symbol and needed to be moved manually.

- Added space below non doc-string comments to make it clear
  these aren't comments for the symbols directly below them.
- Use doxy sections for some headers.
