fix entities for list requests

I put the wrong entities in my previous commit.
However, there is a reason for that:

get_releases_by_* etc. are named wrong.
You don't get releases, you get a discid entity which includes a list of
releases.

Merge branch 'list_requests' into doc_changes

We don't want to document the wrong includes.

docs: set module

This way we don't have to specify the module for every function again.
This also makes the module turn up in the module index.

We can use `currentmodule` to set the module in other files,
without adding these files as links targets for the module.
