By templating on the <chrono> types and unconditionally using
duration_cast to coerce the duration into a milliseconds, we
violate a principal design rule of <chrono>, namely that non-
narrowing conversions are implicit, but narrowing conversions
need duration_cast. By accepting any duration, we allow non-
sensical code such as
QTimer::singleShot(10us, ...)
to compile, which is misleading, since it's actually a zero-
timeout timer.
Overloading a non-template with a template also has adverse
effects: it breaks qOverload().
Fix by replacing the function templates with functions that
just take std::chrono::milliseconds. This way, benign code
such as
QTimer::singleShot(10s, ...)
QTimer::singleShot(10min, ...)
QTimer::singleShot(1h, ...)
work as expected, but attempts to use sub-millisecond
resolution fails to compile / needs an explicit user-
provided duration_cast.
To allow future extension to more precise timers, forcibly
inline the functions, so they don't partake in the ABI of the
class and we can later support sub-millisecond resolution by
simply taking micro- or nano- instead of milliseconds.

The fix is trivial, but the patch adds a new QSettings tests that iterates most
of the QMetaTypes and verifies that storing and retrieving them again gives the
same value. This is a more complete test than the testVariantTypes tests, which
is limited to a subset of the QVariant types. The new tests borrows logic from
the QMetaType test machinery.
QSettings has been Q_ENUM'ified in the process, for improved debug output.
Note that on backends such as the INI backend, the metatype of the QVariant read
from the settings will be a string, so it won't match the input QVariant type,
but the result of converting that to the original value type should still work.

One of the good features of the new connection style is that
implicit conversion is performed for the connection arguments.
However, this is also a bad feature when it comes to the old
C remnants in the C++ language: for instance, doubles implicitly
convert to ints, possibly losing precision (and GCC/Clang do not
even warn about those under -Wall, only MSVC does) or even
triggering undefined behavior.
For this reason, when using braced initialization, C++11
disables narrowing conversions or floating/integral conversions.
Use this feature when checking the arguments of a PMF-style
signal/slot connection. Technically this makes the program
ill-formed, however GCC still accepts it (but at least
warns under -Wall).
Hence, add a way to disable these implicit conversions.
This is a opt-in and guarded by a macro, as it's a source
incompatible change.
[ChangeLog][QtCore][QObject] The
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT macro has been added.
When using the new connection syntax (PMF-based) this macro
makes it illegal to narrow the arguments carried by the signal,
and/or to perform floating point to integral implicit
conversions on them. When the macro is defined,
depending on your compiler a QObject::connect() statement
triggering such conversions will now fail to compile.

This patch makes sure that all events posted using Qt on top of the
GLib event loop have the loopLevel counter incremented.
This is done since Qt depends on the fact that all deleteLater() calls
are issued within the scope of some signal handler (in other words,
triggered by the chain sendEvent() -> notifyInternal2()).
There is a side effect though: in the conditions affected by this
patch, that is deleteLater()s issued within a glib event handler for
example, manually calling processEvents() or sendPostedEvents() with
or without the QEvent::DeferredDelete flag has the same effect, and
deferred deleted events are always processed.
While this is not a currently working feature which the patch breaks,
this side effect seems to be difficult to avoid without separating
sendPostedEvents() and processEvents() into a public and a private
method, in order to detect when they are manually called.
Such change could perhaps be done for Qt6.
An autotest for QTBUG-36434 is also included.
Autotesting for QTBUG-32859 seems to be more challenging in this
