Fix crash when app font is added

Loading app fonts will clear the application font cache, but
QFontPrivate::engineWithScript will try to load the font again,
in Mac the font engine used here must be the one used for shaping,
because subsequent sub font engines may be added to it during the
shaping process (QCoreTextFontEngineMulti::stringToCMap). That is
why we need to fetch the font engine directly from QTextEngine's
fontEngine cache instead of QFontCache.

Remove Qt 4.3 binary compatibility for MSVC

When we removed the useless "const" in the return type, we broke
compatibility with a few compilers that include the return type in the
mangling. We don't need that anymore in Qt 5.

This change should have had a ### Qt5 mark everywhere, not just in a
comment in qstring.cpp.

Remove the definition of QT_NO_FPU based on the processor or WS

The definition is just wrong these days. Modern ARMv7 and MIPS have
FPUs. Maybe AVR32, SH or SH4A don't, but then QT_NO_FPU should be
defined in the qplatformdefs.h for those platforms.

More importantly, since QPA is the only supported architecture for Qt
5, we definitely don't want to say that no platforms have no FPU.

Still let qreal be defined to float on ARM, though: on Cortex-A8,
which is the current norm these days, float performance is better than
double performance.

Don't issue GL calls when the geometry is empty

This works as a band-aid and optimization for QT-5104, because in the
text in the example, which contains latin text and has a latin default
font set, will think of all spaces between the cyrillic characters as
latin characters, hence it will make separate text items for them and
issue separate glDrawElements() calls. By cutting off if there are no
glyphs to draw, we can avoid hitting the actual bug for this and several
other use cases, making it less likely to happen.

Fixed opengldesktop configure test for mac.

This configure test has never worked for mac.

In a non-qpa configuration, this didn't matter, as the configure script
would skip this configure test on mac.  The configure script could also
be modified to skip the configure test in the qpa case, but it seems
cleaner to make the test actually work.

Qt Compositor propagates screen orientation changes to wayland, which
are then picked up by the wayland client. The wayland client then sends
a QScreenOrientationChangeEvent to QApplication, which can handle the

Add Happy-Eyeballs style IPv6 connection establishing.

In the cases where a DNS lookup will give you both an IPv4 and IPv6
address, this will start two connection channels at the same time.
One trying to connect using IPv4 and one on IPv6. This is done so
that we can use the fastest one for the connection. To do this we
have to do the hostlookup in the connection. The result is then
in the cache for the individual socket so it will not need to do
another lookup.
