bookmaker does deprecated

Bookmaker does not require documentation for public symbols
described as "deprecated", "private", or "experimental".
Adding one of these words (case-insensitive) to the symbol
description in the include file tells bookmaker that the bmh file
should not include documentation, and the generated markdown
should omit it in its indices and descriptions.

Symbols marked as "to be deprecated" or "may be deprecated"
are still regarded as public and documented.

Private notes in the includes that start with TODO: are
omitted as well.

This CL updated generated includes to describe its symbols
accordingly. The includes will be fully regenerated in a future
CL. The corresponding documentation has been deleted from the
bmh files, and the web markup has been regenerated.
