cf52379422 Do not run unit tests in release builds

anyway.

cbba348a83 always inline custom operator new/delete to avoid spurious warnings 
GCC 11 warns incorrectly about mismatched new/delete because it auto
inlines one but not the other, force inline those function to fix that.

e3957bb24c Generate different parse_quoted_balanced for each quote pair 
This seems to slightly improve parse speed which is where kakoune
spends most of its time during startup.

a4dd89f214 Improve code-generation for Strings 
Make String::Data use trivial copy of the short/long union to avoid

the compiler on moved-from Strings.

c643cd4467 Fix blitting of windows halfway through double-width codepoint 
Display a whitespace in place of the uncovered half of the codepoint.

(I know this is incorrect and we should be considering grapheme clusters
instead of codepoints, but this is a far bigger refactoring and another
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.

and tolerating them avoids the crash.

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.

Fixes #3482.

72271ce529 Handle skipped characters with erase line (EL) instead of insert blank (ICH) 
insert blank seems to behave differently between terminals and would
be less efficient because it still has to shift all following characters
(that we will overwrite anyway).
