Building with Qt6

[gvanem]

Building qt-dab -s4 using Qt6 has issues since some enum stuff was moved from QString into Qt name-space. The compile error (from clang-cl):

radio.cpp(2913,35): error: no member named 'SkipEmptyParts' in 'QString'; did you mean 'Qt::SkipEmptyParts'?
        QStringList list = s.split (":", QString::SkipEmptyParts);
                                         ^~~~~~~~~~~~~~~~~~~~~~~
                                         Qt::SkipEmptyParts
f:/gv/Qt/6.2.4/msvc2019_64/include/QtCore\qnamespace.h(153,9): note: 'Qt::SkipEmptyParts' declared here
        SkipEmptyParts = 0x1,
        ^

Similar for QPalette::Background:

radio.cpp(636,34): error: no member named 'Background' in 'QPalette'
        lcdPalette. setColor (QPalette::Background, Qt::white);
                              ~~~~~~~~~~^

I suppose this could be patched into:

@JvanKatwijk I see you have patched to Qt::SkipEmptyParts in some places. But other places are missing. But the most serious part is that audio does not work in Qt6 + Windows. Hence closing.
