Problem: The 'statuscolumn' width is being estimated without the
proper context. In particular, this resulted in the fact
that a custom fold column could be included in the estimated
`number_width()`, and doubly added when actually drawing the
statuscolumn due to `win_col_off()` also adding the
`'foldcolumn'` width. Resulting in a status column that is
`'foldcolumn'` cells wider than necessary.
Solution: Estimate 'statuscolumn' width in `get_statuscol_str()` when
a buffer's line count has changed.
Problem: When a folded line has virtual lines attached, the following
problems occur:
- The virtual lines are drawn empty.
- The 'foldtext' line is drawn empty.
- The cursor is drawn incorrectly.
Solution: Check whether virtual lines belong to a folded line.

This is a false positive as "did_emsg" can be set by get_syntax_attr()
Example: get_syntax_attr() -> syn_current_attr() -> syn_getcurline()
-> ml_get_buf() -> siemsg() -> semsgv() -> emsg() -> emsg_multiline()
Problem: The default fold column, as well as the 'statuscolumn', were
drawn unnecessarily/unexpectedly for virtual lines placed
with `virt_lines_leftcol` set.
Solution: Skip the column states if a virtual line with
`virt_lines_leftcol` set will be drawn.
Problem: The `'statuscolumn'` was not re-evaluated for wrapped lines,
when preceded by virtual/filler lines. There was also no way
to distinguish virtual and wrapped lines in the status column.
Solution: Make sure to rebuild the statuscolumn, and replace variable
`v:wrap` with `v:virtnum`. `v:virtnum` is negative when drawing
virtual lines, zero when drawing the actual buffer line, and
positive when drawing the wrapped part of a buffer line.
test(statuscolumn): add more tests more wrapped lines
Also initialize a "relnum" variable to suppress a Coverity warning.
The uninitialized value wasn't actually used by build_statuscol_str().
Problem: Unable to customize the column next to a window ('gutter').
Solution: Add 'statuscolumn' option that follows the 'statusline' syntax,
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.
Problem: Match highlighting of tab too short.
Solution: Do not stop match highlighting if on a Tab. (Christian Brabandt,

Problem: Match highlighting continues over breakindent.
Solution: Stop before the end column. (closesvim/vim#9242)

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.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Before only win_line lines were considered. this applies nodelta
to all screen elements. Causes some failures, which might indeed
indicate excessive redraws.
- Added 'spell' option to extmarks:
Extmarks with this set will have the region spellchecked.
- Added 'noplainbuffer' option to 'spelloptions':
This is used to tell Neovim not to spellcheck the buffer. The old
behaviour was to spell check the whole buffer unless :syntax was set.
- Added spelling support to the treesitter highlighter:
@spell captures in highlights.scm are used to define regions which
should be spell checked.
- Added support for navigating spell errors for extmarks:
Works for both ephemeral and static extmarks
- Added '_on_spell_nav' callback for decoration providers:
Since ephemeral callbacks are only drawn for the visible screen,
providers must implement this callback to instruct Neovim which
regions in the buffer need can be spell checked.
The callback takes a start position and an end position.
Note: this callback is subject to change hence the _ prefix.
- Added spell captures for built-in support languages

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: 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()
