Sadly, inline namespaces are resulting in ambiguities. With two
declarations
QtJniTypes::android::io::File
and
QtJniTypes::org::qtproject::qt::android::QtWindow
referring to QtJniTypes::android already is ambiguous if `org`,
`qtproject`, and `qt` namespaces are all inline. This breaks the
idea behind Q_DECLARE_JNI_CLASS as a variadic macro that generates types
that we can transparently use as QtJniTypes.
So remove the inline keyword from the namespace declarations. The macro
might still be the way to go, but user code will to either fully qualify
the types, or use `using namespace QtJniTypes::java::lang` to use e.g.
the `String` type without ambiguities.
Types declared with the two-argument overload continue to live
directly in the QtJniTypes namespace anyway.
As a drive-by, break the excessively long lines.

A locale's UI language includes the script, e.g. the QLocale::uiLanguage
list for the Australian locale en_AU is {"en_Latn_AU", "en_AU", "en"}.
The old code iterated over each language in the outer loop, and for each
language tried several times, removing a segment from the back with each
try in the inner loop. The de-facto search order was then
en_Latn_AU
en_latn_au
en_Latn
en_latn
en
en_AU
en_au
en
Usually, translation files are provided for country_Territory, i.e.
en_AU. But if an en file (for a generic English translation) was also
present, then en_AU was never tried.
Fix this by breaking the logic into two loops: first, create a list of
candidates by removing segments from each UI Language. Then sort that
list of candidates so that entries with more segments come first. The
search order is now:
en_Latn_AU
en_latn_au
en_Latn
en_latn
en_AU
en_au
en
This way, en_AU gets loaded correctly, before en is tried.
Adjust the test, which was essentially duplicating the logic from
QTranslator to generate files. This only tested that two identical loops
result in the same thing. Instead of using the system locale, make the
test data-driven, and explicitly try en_US and en_AU, with candidate
files generated based on a hardcoded list for each data row.

Make the macro variadic. For N > 2 arguments, interpret the first
N-2 arguments as nested namespaces that are declared as inline
namespaces. We can then construct the signature string from those
namespaces, so
Q_DECLARE_JNI_CLASS(String, "java/lang/String")
is equivalent to
Q_DECLARE_JNI_CLASS(java, lang, String)
except that with the second overload, the C++ type will be in the
QtJniTypes::java::lang namespace. Since both the java and the lang
namespaces are made inline, QtJniTypes::String still works.
This helps with avoiding conflicts, as there might be Java classes
in different packages, but with the same name.

The relational operators were removed in
8652c79df0 with the argument that they
do not have a total order. Back than it was a valid argument, because Qt
did not support any of the C++20 ordering types.
Now Qt has its own implementation for all three ordering types, so we
could technically add relational operators and claim that QVariant
provides partial ordering.
However, that could potentially lead to many bugs and/or unexpected
results, if people start using QVariant as a key in std::map/QMap
containers.
We do not want that to happen, so we only use the helper macros to
implement (in)equality operators.
This commit also extends the unit tests, providing more extensive
testing of (in)equality operators and the pre-existing

Which will be used to represent timer IDs. Thanks to Marc for the idea
to use "a strongly typed int".
QTimer got a new id() method that returns Qt::TimerId (can't overload
timerId()). Various classes in qtbase have a member named timerId(), but
a new method is needed anyway in QTimer so id() it is (this is the
reason QChronoTimer only has id() and no timerId()). Besides
timer.timerId() has an extra "timer".
This commit fixes the inconsistency between QObject using `0` timer id
to indicate "failed to start", while QTimer::timerId() returned `-1` to
indicate "timer is inactive". QTimer::id(), being a new method and all,
now returns Qt::TimerId::Invalid, which has value `0`, so that the
values match between the two classes. Extend the unittests to ensure
QTimer::timerId()'s behavior is preserved.

The interval in QTimer is a QProperty of type int, which means it's
limited to the number of milliseconds that would fit in an int (~24
days), this could cause overflow if a user constructs a QTimer with an
interval > INT_MAX milliseconds. And it can't be easily changed to use
qint64/std::chrono::nanoseconds:
- changing the getters to return qint64 means user code would have
narrowing conversions
- the bindable QProperty interval can't be changed to qint64 during
Qt6's lifetime without the risk of breaking user code
- adding a new bindable QProperty that is qint64/nanoseconds is an
option, but it has the complication of what to do with the int
interval; set it when setInterval(milliseconds) is used by using
saturation arithmetic? and what about notifying observers of the
changed interval?
Thus the idea of creating a new stop-gap class, QChronoTimer, as a
cleaner solution. Both classes use QTimerPrivate.
During the lifetime of Qt6, QTimer's interval range is about 24 days,
whereas QChronoTimer's interval range is about 292 years
(duration_cast<years>nanoseconds::max()).
Currently the plan is to fold QChronotTimer back into QTimer in Qt7.
Mark all QPropertyS in the new class as FINAL since they aren't
intended to be overridden; this offers a performance boost for QML[1].

QObject::startTimer() returns 0 in case of failure, for example when

However, QTimer internally uses -1 as an invalid timer id.
This could lead to a situation when the timer was not really started,
but QTimer::isActive() returned true.
This patch fixes it in two ways:
- check the return value of QObject::startTimer() and treat 0 as an
error.
- do not treat 0 as a valid timer id when calculating the active state.
