Problem:
1. Some calls to preserve_exit() don't put a message in IObuff, so the
IObuff printed by preserve_exit() contains unrelated information.
2. If a TUI client runs out of memory or receives a deadly signal, the
error message is shown on alternate screen and cannot be easily seen
because the TUI exits alternate screen soon afterwards.
Solution:
Pass error message to preserve_exit() and exit alternate screen before
printing it.
Note that this doesn't fix the problem that server error messages cannot
be easily seen on exit. This is tracked in #21608 and #21843.
- The defined interface for the UI is only the RPC protocol. The original
UI interface as an array of function pointers fill no function.
- On the server, all the UI:s are all RPC channels.
- ui.c is only used on the server.
- The compositor is a preprocessing step for single-grid UI:s
- on the client, ui_client and tui talk directly to each other
- we still do module separation, as ui_client.c could form the basis
of a libnvim client module later.
Items for later PR:s
- vim.ui_attach is still an unhappy child, reconsider based on plugin experience.
- the flags in ui_events.in.h are still a mess. Can be simplified now.
- UX for remote attachment needs more work.
- startup for client can be simplified further (think of the millisecs we can save)
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.
Enable and fix bugprone-misplaced-widening-cast warning.
Fix some modernize-macro-to-enum and readability-else-after-return
warnings, but don't enable them. While the warnings can be useful, they
are in general too noisy to enable.
all pointers returned by arena_alloc residing in arena block should be
properly aligned
to meet neovim's alignment requirements but keeping it simple settle on
ARENA_ALIGN = MAX(sizeof(void *), sizeof(double)).
Problem: Command line history code is spread out.
Solution: Put the code in a new file. (Yegappan Lakshmanan, closesvim/vim#4779)
Also graduate the +cmdline_hist feature.

Problem: File for Insert mode is much too big.
Solution: Split off the code for Insert completion. (Yegappan Lakshmanan,

Cherry-pick ins_compl_len() -> get_compl_len() from patch 8.2.4001.
Revert a71c5e9eb9: ctrl_x_mode is no
longer a global variable, so l_ctrl_x_mode is no longer needed.
Problem: With EXITFREE defined terminal menus are not cleared.
Solution: Also clear terminal menus. Remove condition that is always true.

Note for external UIs: Nvim can now emit multiple "redraw" event batches
before a final "flush" event is received. To retain existing behavior,
clients should make sure to update visible state at an explicit "flush"
event, not just the end of a "redraw" batch of event.
* Get rid of copy_object() blizzard in the auto-generated ui_event layer
* Special case "grid_line" by encoding screen state directly to
msgpack events with no intermediate API events.
* Get rid of the arcane notion of referring to the screen as the "shell"
* Array and Dictionary are kvec_t:s, so define them as such.
* Allow kvec_t:s, such as Arrays and Dictionaries, to be allocated with
a predetermined size within an arena.
* Eliminate redundant capacity checking when filling such kvec_t:s
with values.
drawback: tracing memory errors with ASAN is less accurate for arena
allocated memory.
Therefore, to start with it is being used for Object types around
serialization/deserialization exclusively. This is going to have
a large impact especially when TUI is refactored as a co-prosess
as all UI events will be serialized and deserialized by nvim itself.
Add space around arithmetic operators '+' and '-'.
Remove space between back-to-back parentheses, i.e. ')(' vs. ') ('.
Remove space between '((' or '))' of control statements.
Add space between ')' and '{' of control statements.
Remove space between function name and '(' on function declaration.
Collapse empty blocks between '{' and '}'.
Remove newline at the end of the file.
Remove newline between 'enum' and '{'.
Remove newline between '}' and ')' in a function invocation.
Remove newline between '}' and 'while' of 'do' statement.
Problem: The ModeChanged autocmd event is inefficient.
Solution: Avoid allocating memory. (closesvim/vim#10134) Rename
trigger_modechanged() to may_trigger_modechanged().

Make v:event readonly for ModeChanged.
Problem: Syntax coloring and highlighting is in one big file.
Solution: Move the highlighting to a separate file. (Yegappan Lakshmanan,

Problem: No generic way to trigger an autocommand on mode change.
Solution: Add the ModeChanged autocommand event. (Magnus Gross, closesvim/vim#8856)

N/A patches for version.c:
vim-patch:8.2.3434: function prototype for trigger_modechanged() is incomplete
Problem: Function prototype for trigger_modechanged() is incomplete.
Solution: Add "void".
28e591dd50Fixes#4399.
Fixes#7416.
Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.

* refactor: format with uncrustify
* fixup(dundar): fix functions comments
* fixup(dundar): remove space between variable and ++/--
* fixup(dundar): better workaround for macro attributes
This is done to be able to better use uncrustify rules for macros
* fixup(justin): make preprocessors follow neovim style guide

"Pointer to local array 'sourcing_name_buf' is stored outside the scope
of this array. Such a pointer will become invalid."
False positive: `sourcing_name = save_sourcing_name` before returning
from this scope.
Problem: Using freed memory in quickfix code. (Dominique Pelle)
Solution: Add the quickfix_busy() flag to postpone deleting quickfix lists
until it is safe. (Yegappan Lakshmanan, closes#3538)
