vim-patch:8.1.1807: more functions can be used as a method

Problem:    More functions can be used as a method.
Solution:   Add append(), appendbufline(), assert_equal(), etc.
            Also add the :eval command.
https://github.com/vim/vim/commit/25e42231d3ee27feec2568fa4be2aa2bfba82ae5

:eval is already ported.
