vim-patch:8.1.2342: random number generator in Vim script is slow
Problem: Random number generator in Vim script is slow.
Solution: Add rand() and srand(). (Yasuhiro Matsumoto, closes vim/vim#1277)
https://github.com/vim/vim/commit/06b0b4bc27077013e9b4b48fd1d9b33e543ccf99
Add missing method call usage to builtin.txt.
vim_time and test_settime is N/A.
Add a modeline to test_random.vim.
Use typval_T* over listitem_T* vars so we don't need to use TV_LIST_ITEM_TV all
over the place...
Remove NULL list checks (tv_list_len covers this).
