Frees up two bytes in GPUCell. Doesn't require a minimum texture row
size. Makes a bunch of code faster. Index uses 31 bits which gives us
2,147,483,647 aka ~ 2 billion sprites.
We now buffer the key events until the kitten tells us it is ready.
Without this the key presses are delivered to the underlying window
as the kitten's overlay window was not being focused until the kitten
set the ready message.

[Python docs](https://docs.python.org/3/c-api/intro.html) say:

Make it so. Since data-types.h is already included first in a lot of
*.c and *.h files, let's use that one.
Also fix the includes in launcher.
This is similar to commit 8e84b2145 (Re-order includes for
"_POSIX_C_SOURCE", 2018-06-02).
Also add an explicit error for this case, to make the resolution more
obvious? Here's the error when I try to include <stdlib.h> in screen.c:

Now can use the full range of standard mouse cursor shapes similar to
those supported by browsers via the CSS cursor property.
Still needs to be fully implemented for cocoa backend.
This commit introduces the Unicode placeholder image placement method.
In particular:
- Virtual placements can be created by passing `U=1` in a put command.
- Images with virtual placements can be displayed using the placeholder
character `U+10EEEE` with diacritics indicating rows and columns.
- The image ID is indicated by the foreground color of the placeholder.
Additionally, the most significant byte of the ID can be specified via
the third diacritic.
- Underline color can be optionally used to specify the placement ID.
- A bug was fixed, which caused incomplete image removal when it was
overwritten by another image with the same ID.
This allows us to have newline not affect the wrap status of a line.
Now a lines wrapping status is changed only when the last cell
in the line is changed. This actually matches the behavior of many other
terminal emulators so is probably a good thing from a ecosystem
compatibility perspective.
The fish shell expects this weird behavior of newline not changing
wrapping status, for unknown reasons, which is the actual motivation for
doing all this work.
Fixes#5766
