Allow selecting fonts with irregular style names

Fonts like "Helvetica Neue UltraLight" or "Skia Regular Black
Condensed" can't be selected in Qt because either they don't
report correct numeric values for weight/stretch/etc. or these
values are not mapped from QFont enums in a linear way. Thus
we provide a shortcut to select these fonts with PostScript
name or full name without resorting to family name matching in
QFontDatabase (these fonts are not registered in font database
anyway). After this, we can simply use:

    QFont font("Helvetica Neue");
    font.setStyleName("UltraLight");

to select these fonts. QCoreTextFontEngineMulti matched like
this can be created directly from the CTFontRef instance
instead of creating from the font name, making this process
faster.

what will be used in comparisons and drawing calls. The vectors are
optimizations to avoid unnecessary copying if the user wants to use
the QVector based API (which makes it easier to manage the memory.)
This reflected in the functions that return QVectors, which will
return the stored vector if and only if it is identical to the
current pointer. Otherwise we will have to copy the memory.

The internal addition operators in QGlyphRun have been removed since

if the two glyph runs are based on different fonts.

Made tst_QWidget::repaintWhenChildDeleted() pass.

Implement some missing functionality in QWidget::destroy().

Prevent tst_QWidget::showAndMoveChild() from failing on KDE.

Since we grab the desktop the KDE task bar appears on top of the window
we're interested in. It's preferable to make the window a bit smaller.
