Fixes for Sphinx version 7.

[sayravai]

Description

Some fixes to make compilation go through with Sphinx v7.4.7, which is apparently slightly stricter with the syntax, and no longer supports the master_doc setting. The master_doc to root_doc change was already made in Sphinx 4.0.0b1 so this should also compile with RST tools 1.4 (not tested).
