drawscreen.c vs screen.c makes absolutely no sense.
The screen exists only to draw upon it, therefore helper functions
are distributed randomly between screen.c and the file that
does the redrawing. In addition screen.c does a lot of drawing on the
screen.
It made more sense for vim/vim as our grid.c is their screen.c
Not sure if we want to dump all the code for option chars into
optionstr.c, so keep these in a optionchar.c for now.
Problem: Scrolling two lines with even line count and 'scrolloff' set.

allowing to customize the status column. Also supporting the %@
click execute function label. Adds new items @C and @s which
will print the fold and sign columns. Line numbers and signs
can be clicked, highlighted, aligned, transformed, margined etc.

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.

it since this only works fully for .c files and not headers.

This was used in the past with assumption that curwin/curbuf
is "special" but this has not been true since basically forever
at this point.
Reduce NOT_VALID/CLEAR panic in options.lua . These should not
be set if an effect of the option is causing something
which by itself invokes redraw_later().
Problem: There is no way to get the byte index from a virtual column.

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()

The size of long varies depending on architecture, in contrast to the
MAXLNUM constant which sets the maximum allowable number of lines to
2^32-1. This discrepancy may lead to hard to detect bugs, for example
https://github.com/neovim/neovim/issues/18454. Setting linenr_T to a
fix maximum size of 2^32-1 will prevent this type of errors in the
future.
Also change the variables `amount` and `amount_after` to be linenr_T
since they're referring to "the line number difference" between two
texts.
Add space around arithmetic operators '+' and '-'.
Remove space between back-to-back parentheses, i.e. ')(' vs. ') ('.
Remove space between '((' or '))' of control statements.
Add space between ')' and '{' of control statements.
Remove space between function name and '(' on function declaration.
Collapse empty blocks between '{' and '}'.
Remove newline at the end of the file.
Remove newline between 'enum' and '{'.
Remove newline between '}' and ')' in a function invocation.
Remove newline between '}' and 'while' of 'do' statement.
The check in redraw_for_cursorline() is not needed because VALID_VIRTCOL
is always cleared when the cursor moves to another line, so the check in
redraw_for_cursorcolumn() is enough.
Problem: With 'nowrap' cursor position is unexected in narrow window.

vim-patch:8.2.4614: redrawing too much when 'cursorline' is set
Problem: Redrawing too much when 'cursorline' is set and jumping around.
Solution: Rely on win_update() to redraw the current and previous cursor
line, do not mark lines as modified. (closesvim/vim#9996)
c20e46a4e3
This doesn't match the patch exactly, because I missed some lines when
porting patch 8.1.2029, and these lines were removed in this patch.
This also makes win_update() always update for 'concealcursor' like how
it always updates for 'cursorline', as 'cursorline' and 'concealcursor'
redrawing logic has been unified in Nvim.
As redrawing for 'cursorline' now always only requires VALID redraw
type, it is no longer necessary to call redraw_for_cursorline() in
nvim_win_set_cursor().
