PROBLEM
------------------------------------------------------------------------
$NVIM_LISTEN_ADDRESS has conflicting purposes as both a parameter ("the
current process should listen on this address") and a descriptor ("the
current process is a child of this address").
This contradiction means the presence of NVIM_LISTEN_ADDRESS is
ambiguous, so child Nvim always tries to listen on its _parent's_
socket. This is the cause of lots of "Failed to start server" spam in
our test/CI logs:
WARN 2022-04-30… server_start:154: Failed to start server: address already in use: \\.\pipe\nvim-4480-0
WARN 2022-04-30… server_start:154: Failed to start server: address already in use: \\.\pipe\nvim-2168-0
SOLUTION
------------------------------------------------------------------------
1. Set $NVIM to the parent v:servername, *only* in child processes.
- Now the correct way to detect a "parent" Nvim is to check for $NVIM.
2. Do NOT set $NVIM_LISTEN_ADDRESS in child processes.
3. On startup if $NVIM_LISTEN_ADDRESS exists, unset it immediately after
server init.
4. Open a channel to parent automatically, expose it as v:parent.

Ref #8696
Problem: When there is a partially matching map and modifyOtherKeys is
active a full map may not work.
Solution: Only simplify modifiers when there is no matching mapping.

Omit test as it sends terminal codes. Use a Lua test instead.
Problem: CTRL-R CTRL-R doesn't work with modifyOtherKeys.
Solution: Allow key codes when fetching argument for CTRL-R. (closesvim/vim#5266)
Also fix CTRL-G in Insert mode.

Omit test as it sends terminal codes. Use a Lua test instead.
Problem: Mapping with partly modifyOtherKeys code does not work.
Solution: If there is no mapping with a separate modifier include the
modifier in the key and then try mapping again. (closesvim/vim#6200)

Use KEYLEN_PART_KEY for incomplete modifier sequence.
Omit test as it sends terminal codes. Use a Lua test instead.
Problem: Dropping modifier when putting a character back in typeahead.
Solution: Add modifier to ins_char_typebuf(). (closesvim/vim#6158)

Vim's test doesn't seem to work properly as the hit-enter prompt seems
to be delayed. Add a Lua screen test.
Problem: CurSearch highlight does not work for multi-line match.
Solution: Check cursor position before adjusting columns. (closesvim/vim#10133)

Problem: Current instance of last search pattern not easily spotted.
Solution: Add CurSearch highlighting. (closesvim/vim#10133)

This fixes CurSearch highlight for multiline match.
Omit screen redrawing code because Nvim redraws CurSearch differently.
Problem: Cursorcolumn is sometimes not correct.
Solution: Recompute the cursor column when entering Insert mode and the
cursor is on a character wider than a screen cell.

Problem: 'cursorline' not always updated with 'cursorlineopt' is
"screenline".
Solution: Call check_redraw_cursorline() more often. (closesvim/vim#10013)

Code was reverted in patch 8.2.4638, so this just ports the test.
Problem: Superfluous check if a redraw is needed for 'cursorline'.
Solution: Remove check_redraw_cursorline(). (closesvim/vim#10030, closesvim/vim#10029)

redraw_after_callback() is N/A.
Omits changes that just revert code from patch 8.2.4630.
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.
Ref: #9342
Adds the option to have a single global statusline for the current window at the bottom of the screen instead of a statusline at the bottom of every window. Enabled by setting `laststatus = 3`.
Due to the fact that statuslines at the bottom of windows are removed when global statusline is enabled, horizontal separators are used instead to separate horizontal splits. The horizontal separator character is configurable through the`horiz` item in `'fillchars'`. Separator connector characters are also used to connect the horizontal and vertical separators together, which are also configurable through the `horizup`, `horizdown`, `vertleft`, `vertright` and `verthoriz` items in `fillchars`.
The window separators are highlighted using the `WinSeparator` highlight group, which supersedes `VertSplit` and is linked to `VertSplit` by default in order to maintain backwards compatibility.
Don't add sign extmarks to state->active. Instead when drawing signs,
perform a full line scan for sign marks. This allows decor_redraw_line
to be moved back inside the `!number_only` block in screen.c, which
prevents decor scans when redrawing the number column when
'relativenumber' is set.
