As of change a094af0017, X11 now joins
other platforms in having a fake screen if no physical screens are
attached, rather than ever allowing QGuiApplication::screens() to
return an empty list or QGuiApplication::primaryScreen() to return
null. This is more consistent across platforms and helps to prevent
bugs in applications which want to use QScreen in some context but
fail to check whether it exists.
[ChangeLog][X11] In case there are no physical screens attached,
QGuiApplication::screens() and QGuiApplication::primaryScreen() will
return a placeholder QScreen object.

... but they were only marked as bidirectional.
Fixed.
This change is slightly BiC, because if some class used tag
dispatching on this iterator type, a recompile might now
pick a different overload, and the old one may not be
available to a user anymore (no longer instantiated).
I do not think Qt uses that technique, yet, though. Not on
iterator categories, at least.

For QLatin1String, operator== is overloaded, so comparing to a latin-1
(C) string literal is efficient, since strlen() is comparatively fast.
OTOH, QStringLiteral, when not using RVO, litters the code with
QString dtor calls, which are not inline. Worse, absent lambdas,
it even allocates memory.
So, just compare using QLatin1String instead.

The old code did the equivalent of strcpy(), thus stopping
at the first NUL byte, ignoring the QLatin1String's size().
That is not acceptable, for two reasons:
1. Appending QLatin1String to a QString uses the size(), too.
2. The QConcatenable claims an ExactSize = true, so
it cannot go and write less data than it's own
size() said it would. Even worse, it will happily
write _more_ data, too, if the QLatin1String is
not properly zero-terminated.
This change has low risk, because the equivalent change
to the QString branch has been applied between 5.2 and
5.3 (in fd0f1bc3), with no complaints from the user base.
It is also in a branch that is very unlikely to be taken:
Since QConcatenable<QLatin1String> is setting ConvertTo
to QString, any QStringBuilder expression containing it
will only implicitly convert to QString, not QByteArray.
In fact, I don't even know how to make it invoke the
changed code in normal operation...

Whenever there are spies installed, we call out to the main thread to
call to the kded/kiod message spies. This allows the spy code to do just
about anything, where previously it was restricted in what it could do
to avoid deadlocking or triggering assertions if it recursed back into
QDBusConnection code in the manager thread. After the spies are done,
the message is re-inserted into the QDBusConnection processing pipeline.
This commit moves the spy handling to after the check for disabled
dispatching, as doing otherwise would mean the message could get
postponed again for no good reason. It's also possible that the main
thread isn't done installing the hooks, so waiting until the dispatching
is enabled is a good idea.
For simplicity, this commit also restricts spying to method calls
only. Signals are no longer spyable.
