Docs build config changes to address warnings and improve rendering

The combined effect of these changes greatly reduces the number of warning
emitted when building the documentation, and improve some rendering. Several
more source files are omitted from the documentation build process that do not
add any information to the documentation but confuse the build system leading
to many warnings and some rendering errors. There are notes in each commit
about the various configuration changes.

These changes are made under both the "Apache 2.0" and the "GNU Lesser General
Public License 2.1 or later" license terms (dual license).
