Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closesvim/vim#4943)
7528d1f6b5
This is an approximation vim-patch 8.1.2057. Applying the patch directly
isn't feasible since our version of screen.c has diverged too much,
however we still introduce drawscreen.c and drawline.c:
- screen.c is now a much smaller file used for low level screen functions
- drawline.c contains everything needed for win_line()
- drawscreen.c contains everything needed for update_screen()

Ref: 84f5463630
Rename:
- `underlineline` to `underdouble`
- `underdot` to `underdotted`
- `underdash` to `underdashed`
`underdouble` also now takes higher precedence than `undercurl`.
If `use_rgb` was false, we would attempt to set the `cterm_bg_color` to the
variable `bg`, which is only retrieved from `bg` and `background` keys, not
`ctermbg`. Same for `fg`. This means the values would be `-1` (the default,
un-got value) and we'd always set the returned values to `0`.
My understanding is `fg/bg` is always "gui" values, so instead we should be
using `ctermbg` when needed.
Nb: when looking around I think this function is currently *always* called with
`use_rgb = true`.

- 831fa45ad8 is related but this doesn't regress that
- The `cterm_normal_fg_color != ae.cterm_fg_color` comparison is originally
carried from patch to patch starting all the way back in 29bc6dfabd where it
was avoiding setting a HL attr. But `hlattrs2dict()` now is just
informational.

Problem: Syntax coloring and highlighting is in one big file.
Solution: Move the highlighting to a separate file. (Yegappan Lakshmanan,

This commit finishes support for colored and styled underlines adding
`CSI 4 : [2,4,5] m` support providing double, dashed, and dotted
underlines
Fixes#17362.
Problem: when accessing `nvim_set_hl` from Lua, empty tables are converted
to empty lists, not dictionaries, resulting in an error for
:lua vim.api.nvim_set_hl(0, "Comment", { cterm = {} })
Workaround: add an empty array as a special case when checking
`dict->cterm.type` and just set `cterm_mask_provided`.
(Proper solution: handle this in `gen_api_dispatch.lua`.)
Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.
