Problem: The eval.c file is too big.
Solution: Move code related to variables to evalvars.c. (Yegappan
Lakshmanan, closesvim/vim#4868)

Name the new file eval/vars.c instead.
- don't immediately vim_strsave and then xfree a heap buffer.
- allow replace_termcodes to take in a buffer instead of allocating it
- grug! memory allocation bad!
This marks the following Vim patches as ported:

Also cherry-pick a change for <unique> mappings from patch 8.2.0807.
Rename map_clear_mode() to do_mapclear().
Most code in keymap.h is for keycode definitions, while most code in
keymap.c is for the parsing and conversion of keycodes.
The name "keymap" may also make people think these two files are for
mappings, while in fact keycodes are used even when no mappings are
involved, so "keycodes" should be a better file name than "keymap".
