patch 8.1.1989: the evalfunc.c file is still too big

Commit: https://github.com/vim/vim/commit/af7645d3733fdd3cd2df03ec7b653601d26969ef
Author: Bram Moolenaar <Bram@vim.org>
Date:   Thu Sep 5 22:33:28 2019 +0200

    patch 8.1.1989: the evalfunc.c file is still too big

    Problem:    The evalfunc.c file is still too big.
    Solution:   Move f_pathshorten() to filepath.c.  Move f_cscope_connection() to
                if_cscope.c.  Move diff_ functions to diff.c.  Move timer_
                functions to ex_cmds2.c.  move callback functions to evalvars.c.
