The position of the cursor should not be decreased if it is already at
the start of the paragraph. This can lead to a crash when trying to
display the caret.

Since the platform is selected at run time (e.g. xcb vs. Wayland), it
is not a good idea to decide at compile time what code is run. Another
example is on macOS, where having xcb libraries available will lead to
lauching the Xquartz whenever LyX is running.
With this patch, things are separated:
- the code is run when run-time platform is "xcb".
- the support code is compiled in when xcb header and libraries are
available.

Fixes ticket #13086.

Instead of baking our own support for -geometry command line option on
Windows (Qt only does that for Xcb), use the fact that Qt 5 provides
the equivalent -qwindowgeometry flag.
All we need to do is to replace the -geometry option with -qwindowgeometry.
This is part of the effort in ticket #13086 to get rid of the
compile-time QPA_XCB define.

The current buffer is part of allRelatives(), contrary to what I
thought. Therefore updateId() increased the buffer id by two.
(cherry picked from commit 2eb4e3d3ca)
Each buffer now has an id which is increased when it is marked dirty
(or when one of its relatives is marked dirty).
This can be a big win since updateMacros is very expensive.

That module was a wrapper over the popen module and it was scheduled to
be removed in Python 3.11.
This code is also compatible with Python 2.

It turns out that Qt font selection via style name is broken on
Windows (QTBUG-101436). As we use our own style name for discriminating
our math fonts and applying proper kerning, we need a fallback method.
With this commit we check for the family name when the style name does
not match. In computing the kerning we also consider the right bearing
reported by the font instead of the width of the enclosing bounding box,
as this produces better results (see bug 13087).
Fixes#13087.
