Problem:
- The `ZR` feature makes it more obvious that we need some sort of flag so that
an `ExitPre` / `QuitPre` / `VimLeave` handler can handle restarts differently
than a normal exit. For example, it's common that users want `:mksession` on
restart, but perhaps not on a normal exit.
- Nvim has no way to report its "uptime".
Solution:
- Introduce `v:starttime`
- Introduce `v:exitreason`
Problem:
- Choosing a new EXX error code is tedious.
- It's possible to accidentally use an EXX error code for different
purposes.
Solution:
Add a lint check which requires EXX error codes to have a :help tag.
This also avoids duplicates because `make doc` does `:helptags ++t doc`
which fails if duplicates are found.
Problem:
The "restart" event has some problems:
- all UI clients must implement a somewhat complex set of setups
- UI must be on the same machine as the server
- only works for the "current" UI
- race/edge case: If the user config has errors / waiting for input, are
all UIs able to attach while Nvim is waiting for input?
Solution:
- Perform the restart on the server, not the client.
- Pass listen address (instead of CLI args) in the UI event.
- Simplifies UI logic: they only need to attach to new address.
- Opens the door for more enhancements in the future, such as allowing
all UIs to reattach instead of only the "current" UI.

Problem:
- `:restart <cmd>` prepends `-c <cmd>` before the original `-c` args (if
any). So the original `-c` args may "override" it, which is
surprising.
- Confusing logic: `v:argv` is partially prepared in `ex_docmd.c`, and
then later `ui.c` skips other parts of it.
Current behavior is nonsense, for example this sequence:
:restart echo "Hello"
:restart +qall echo "Hello" | echo "World"
results in this v:argv:
[
'nvim'
'-c'
'echo "Hello" | echo "World"'
'--embed'
'-c'
'echo "Hello"'
...
]
Whereas after this commit, v:argv is:
[
'nvim'
'--embed'
...
'-c'
'echo "Hello" | echo "World"'
]
Solution:
- Append `-c <cmd>` at the _end_ of `v:argv`, not the start.
- Use a dummy placeholder `+:::` to mark where the "restart command"
appears in `v:argv`.
- Do all `v:argv` preparation in `ex_docmd.c`. This simplifies `ui.c`.
- Drop `-- [files…]` from `v:argv` since it is probably more annoying
than useful. (Users can use sessions to restore files on restart.)
Use double sentence spacing and wrap lines at 'textwidth'. Code
examples and tables were not wrapped unless this had already been done
locally.

Fix incorrect docs in :h ModeChanged.

Problem:
Not easy for a user to tell ":restart" to "run this command(s) after restarting".
Solution:
All ":restart" args following the optional +cmd arg are treated as a big cmdline that is passed as a "-c" CLI arg when restarting nvim.
Problem:
":restart" always executes ":qall" to exit the server.
Solution:
Support ":restart +cmd" so the user can control the command
used to exit the server.

Problem:
Developing/troubleshooting plugins has friction because "restarting"
Nvim requires quitting and manually starting again. #32484
Solution:
- Implement a `:restart` command which emits `restart` UI event.
- Handle the `restart` UI event in the builtin TUI client: stop the
`nvim --embed` server, start a new one, and attach to it.
Problem:
Hidden options are documented despite being no-ops.
Solution:
Remove docs for hidden options.
Move tags for options that we plan to restore, to ":help nvim-missing".
Move tags for permanently removed options, to ":help nvim-removed".
Problem:
The default builtin UI client does not declare its client info. This
reduces discoverability and makes it difficult for plugins to identify
the UI.
Solution:
- Call nvim_set_client_info after attaching, as recommended by `:help dev-ui`.
- Also set the "pid" field.
- Also change `ui_active()` to return a count. Not directly relevant to
this commit, but will be useful later.
Ref #21393
- Move default user commands to _defaults.lua as that now contains all
kinds of defaults rather than just default mappings and menus.
- Remove the :aunmenu as there are no menus when _defaults.lua is run.
Problem: Menu functionality insufficiently tested.
Solution: Add tests. Add menu_info(). (Yegappan Lakshmanan, closesvim/vim#5760)

Omit feedkeys() change: even if "L" flag is implemented it will likely
use input_enqueue(), which already checks for interrupts.
Omit Test_mouse_popup_menu(): already tested in Lua.
Problem:
Since right-click can now show a popup menu, we can provide messaging to
guide users who expect 'mouse' to be disabled by default. So 'mouse' can
now be enabled by default.
Solution:
Do it.
Closes#15521
Problem: Internal error when using :popup.
Solution: When a menu only exists in Terminal mode give an error. (Naruhiko

Problem: No menus specifically for the terminal window.
Solution: Add :tlmenu. (Yee Cheng Chin, closesvim/vim#3439) Add a menu test.

ADDR_OHTER comes from patch 8.1.1241, which has already been ported.
Problem: Can't use :popup for a menu in the terminal. (Wei Zhang)
Solution: Make :popup work in the terminal. Also fix that entries were
included that don't work in the current state.

Neovim already removed `evim` (or any similar flags). The 'insertmode'
option is a weird remnant, so get rid of it.
The 'insertmode' option is replaced with a script that closely emulates
the option. This script is documented at :help 'insertmode'
