- Fix typo in `boost/iterator.hpp`. Fixes #3434.
- Always include `add_reference` header in iterator adaptor header.
* Use `doc/src/*.css` instead of `doc/html/*.css`.
* Remove wiki and people directories.
* Some documentation fixes.
* Left out `minimal.css` changes and boostbook changes because of clashes.
