6548846950 Slight refactoring of bracketed paste feature
Handle begin/end paste directly in paste csi, manage paste buffer
out of get_char, filter Key::Invalid earlier.

get_next_key returning Key::Invalid means there was some input but
it could not be represented as a Key. An empty optional means there
was no input at all.

b2cf74bb4a Implement bracketed paste
Text pasted into Kakoune's normal mode is interpreted as command
sequence, which is probably never what the user wants. Text
pasted during insert mode will be inserted fine but may trigger
auto-indentation hooks which is likely not what users want.

Bracketed paste is pair of escape codes sent by terminals that allow
applications to distinguish between pasted text and typed text.

Let's use this feature to always insert pasted text verbatim, skipping
keymap lookup and the InsertChar hook. In future, we could add a
dedicated Paste hook.

We need to make a decision on whether to paste before or after the
selection. I chose "before" because that's what I'm used to.

TerminalUI::set_on_key has

	EventManager::instance().force_signal(0);

I'm not sure if we want the same for TerminalUI::set_on_paste?
I assume it doesn't matter because they are always called in tandem.

Closes #2465

ad36585b7a Make TerminalUI::get_next_key() helpers static
The only depend on the TerminalUI object which is a singleton, so we
can make them all static.

6acc18373d Add option to set maximum info box width
Some plugins (*cough* kak-lsp) and help texts tend to have immensely long content
in a single line. This generates info boxes that span the entire terminal width.
This is made especially worse on widescreen monitors or at small text size.

This grants user control over how wide these boxes are.

I deliberately avoid pushing this change to `kak-lsp` because it's not the only
plugin that this could help--see the `hook` help text for an example of this
problem in vanilla Kakoune. I would also suggest that since this is a rendering
concern, it be handled by the terminal rendering logic.

b3a1017a26 Remove scrolling detection/optimization in terminal output
Just validate if line changed or not. This should avoid flickering
on terminals such as the linux console that eagerly redraw on line
deletions. Unfortunately this means drawing will use more data and
might add a bit of latency on slow links.

3fc8e29d10 Add support for curly underline and separate underline color
Add support for a third color in face definition that controls
the underline and a 'c' attribute for curly underline (that takes
precedence over 'u' if both are specified)

Allow empty colors to mean default, so that `,,red+u` means the
same as `default,default,red+u`

can of worms to handle with terminal emulators).

428ddeb97b Add 'terminal_synchronized' ui_option to opt-in synchronized output
Synchronized output does not work well with various terminals
(including the linux console). It should also be unnecessary when
not going through a slow link.

This will eventually be removed if it is not proven to be useful
to some users.

de065dad2d terminal_ui: restore termios settings before suspending Kakoune.
TerminalUI::suspend() is responsible for undoing all Kakoune's modifications to
the terminal state, actually suspending the process, then re-applying all the
modifications after Kakoune wakes back up.

Previously, the "undo" and "reapply" steps for termios settings were both after
the suspend point, so on some platforms they were incorrect when the user
arrived back at the shell prompt.

Now, the termios "undo" step is back before the suspend point, and the undo and
reapply steps should be in exactly reversed order.

Fixes #3488.

e760f2df6b Use iTerm2 "synchronised update" sequences around redraws.
In terminals that support it, this sequence causes the terminal to not redraw
*its* output until the application has finished, reducing redraw flickering.

The sequence is defined in:

    https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec

...and is apparently also supported by kitty and libVTE.

insert blank seems to behave differently between terminals and would
