vim-patch:9.0.0303: it is not easy to get information about a script

Problem:    It is not easy to get information about a script.
Solution:   Make getscriptinf() return the version.  When selecting a specific
            script return functions and variables. (Yegappan Lakshmanan,
            closes vim/vim#10991)
