On TUI startup write the CSI sequence that signals to the controlling
terminal that Neovim supports the CSI u scheme for encoding modifiers
documented in [1].
This is similar to, but distinct from, Vim's usage of the `t_TI` and
`t_TE` variables to handle Xterm's `modifyOtherKeys` setting. For a
longer explanation on those differences see [2]. Since Neovim uses
libtermkey for key input handling, we use the CSI u encoding rather than
Xterm's modifyOtherKeys encoding.

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().
Problem: Cursor line not updated when a callback moves the cursor.
Solution: Check if the cursor moved. (closesvim/vim#9970)

redraw_after_callback() is N/A. Nvim handles timers on the main loop.
vim-patch:8.2.4613: return type of swapfile_unchanged() is wrong
Problem: Return type of swapfile_unchanged() is wrong.
Solution: Use "int". (closesvim/vim#10000 Yeah!)

Problem: Highlight and match functionality together in one file.
Solution: Move match functionality to a separate file. (Yegappan Lakshmanan,
closesvim/vim#6352)

If this is not properly escaped doxygen 1.9.3 will not work correctly,
and the documentation generated in local machines will differ with what
is generated in CI.
When pasting, all of key buffer can be consumed, and in case of phase 3
the paste event must be put exactly once, so using rbuffer_read() should
be better here.
Problem: The equivalent class regexp is missing some characters.
Solution: Update the list of equivalent characters. (Dominique Pellé,
closesvim/vim#8029)

Match upstream's indent in s:equivalence_class().
Problem: Syntax coloring and highlighting is in one big file.
Solution: Move the highlighting to a separate file. (Yegappan Lakshmanan,
closesvim/vim#4674)

Name the new file highlight_group.c instead.
