* One automodule in a file for our modules is way too much, so we split it into
files. Unfortunately this means that only one file can have those classes and
functions be linkable from elsewhere.
* Instead we bite the bullet and manually curate the items into pages, and at
the same time subdivide the 'enums and data' page more which is a general
readability and usability win as well.
* We also add some previously not-included functions, and add a doc-build time
check to ensure that functions and classes aren't omitted from the
documentation in future
