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,

The use of 'softtabstop' to set tabSize was introduced in 5d5b068,
replacing 'tabstop'. If we look past the name tabSize and at the actual
purpose of the field, it's the indentation width used when formatting.
This corresponds to the Vim option 'shiftwidth', not 'softtabstop'.
The latter has the comparatively mundane purpose of controlling what
happens when you hit the tab key (and even this is incomplete, as it
fails to account for 'smarttab').
s:EndTermDebug should only be called when exiting if the debugger started
without error, otherwise the plugin breaks.
Vim handles this by using job_setoptions to set the on_exit callback to
s:EndTermDebug after startup succeeds. However, Nvim does not have such
functionality; instead; use s:starting to mimic this behaviour.
Also, introduce s:running to fix s:CheckGdbRunning; it did not work correctly
due to the "[Process exited X]" message keeping the job's channel alive (though
the stream is closed). This means nvim_get_chan_info cannot be used to check if
the debugger has exited, as it may still return a non-empty dict.
