A default-constructed static QBasicAtomicInt at function scope
will be dynamically initialized. It will still be zero-initialized,
but at least GCC adds guard variables for such objects.
When using aggregate initialization, the guard disappears.
Amends 04d6495bf773a6bb0d4fa6980df22d3b81a605b0.

A variable of static storage duration that is not zero-initialized
takes up space in the DATA segment of the executable. By making the
counters start at zero and adding the initial value afterwards, we
move them over to the BSS segment, which does not take up space in
the executable.
Wrap atomics used across function boundaries into small functions,
to avoid code duplication and to increase readability.

We can use 'override' directly since Qt 5.7.
Also remove redundant 'virtual'.

To support multiple displays in the emulator, it is necessary that an
additional EGLFS device integration be added to query information about
the available screens, and to help associate a window surface with a
screen.
