doc/lib-functions: remove warnings

Browse Source 
Building the nixpkgs manual currently triggers a bunch of deprecation
warnings, because every attribute in `lib` is evaluated to see if it's
an attrset to generate locations for.

Instead, share the lib subsets to include in the documentation
between `lib-function-docs` and `lib-function-locations` so they can
coordinate.

Also generate the list of sections instead of duplicating it in
`library.xml`.
