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).

Fixes #3437

484cfae9d1 Use CSI @ instead of emitting lots of spaces 
This greatly reduces the amount of data written for a redraw especially
on big terminals where most of the data is trailing blanks

5466f63eeb Use insert/remove lines escapes to reduce terminal traffic 
Diff against known state and insert/erase relevant lines.

Erase everything first to avoid insertion invalidating lines that
get out of the terminal at bottom.

07750656a8 Blit all window together before outputing them to the tty 
This should reduce flicker, by avoiding transient states where
info/menu windows are not displayed, and paves the way for proper
diffing of the screen.
