Vincent Ambo 0c99dac497 doc: Add automatic generation of library function documentation
Modifies the build process of the manual to invoke nixdoc
automatically to generate XML files with function documentation.

Currently documentation is present for five of the files in `lib/`.

To add another file to the generated docs, both
`doc/functions/library.xml` and `doc/lib-function-docs.nix` must be
updated.
