Resolves trac ticket #10636 (http://trac.ffmpeg.org/ticket/10636). Texinfo 7.0, released in November 2022, changed the names of various functions. Compiling docs with Texinfo 7.0 resulted in warnings and improperly formatted documentation. More old names appear to have been removed in Texinfo 7.1, released October 2023, which causes docs compilation to fail. This commit addresses the issue by adding logic to switch between the old and new function names depending on the Texinfo version. Texinfo 6.8 produces identical documentation before and after the patch.
