This is a refactor extracted from vim-patch 9.0.0067: cannot show virtual text
The logic for inline virtual text is going to be different in nvim than
text property based text in vim, but this refactor is still useful,
as calculation of displayed linesize is going to be stateful in a
similar way.
Problem: Some source files are too big.
Solution: Move text formatting functions to a new file. (Yegappan
Lakshmanan, closesvim/vim#6021)

Omit duplicate docs. It's removed in patch 8.2.3623.
Nvim doesn't seem to need callback_set() as it was omitted when patch 8.1.1437
was first ported.
Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closesvim/vim#4943)

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()

Omit win_redr_ruler() change: winbar may still need redraw.
Omit win_update() changes: Nvim doesn't use `Rows` there.
Omit redraw_asap(): removed.
Problem: If 'operatorfunc' invokes an operator the remembered Visual mode
may be changed. (Naohiro Ono)
Solution: Save and restore the information for redoing the Visual area.

Cherry-pick a line from patch 8.2.0522.
Problem: When re-formatting with an indent expression the first line of a

Solution: Apply the correct indenting function for the first line.

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.
