A default-constructed QDateTime is invalid, but compared equal to a
valid one referencing the start of 1970. This lead to date properties
in QML being initialized invalid but not getting an onChange if the
first value they're set to is the start of 1970.
Fixing that then lead to some tests failing. Indeed, the original
equality check involved using toMSecsSinceEpoch(), whose value is
undefined unless the datetime is valid, without a prior check on its
validity: so ensure all uses of toMSecsSinceEpoch() are guarded with
isValid() checks.
Reworked tst_QDateTime::toSecsSinceEpoch() to use its bool column
(previously unused, after separating from toTime_t(), which uses this
column for "out of time_t's range") for validity of the datetime.
[ChangeLog][QtCore][QDateTime] Invalid datetimes are now treated as
equal and less than all valid ones. They could previously be found
equal to valid datetimes.

There is no year 0 in the proleptic Gregorian calendar, so QDate()
won't be happy if asked for a date in it. Tweak scanning of the data
we get from MS-Win so as to avoid a date calculation that could
otherwise happen in year 0 when constructing
QDateTime(QDate(1, 1, 1), QTime(0, 0, 0), QTimeZone("Australia/Sydney")).
Added a test for this case, which Oliver Wolff has kindly verified
does reproduce the assertion failure. However, Coin is unable to
reproduce, as all its MS builds are configured with -release, so
Q_ASSERT() does nothing. (The relevant code then skips over year 0,
albeit for the wrong reasons, and gets the right results, albeit
inefficiently, leaving no other symptom by which to detect the
problem.)

- Replaced the usages of:
* QDateTime::toTime_t() -> QDateTime::toSecsSinceEpoch().
* QDateTime::fromTime_t() -> QDateTime::fromSecsSinceEpoch().
* QDate::shortDayName() -> QLocale::system().dayName().
* QTime by QElapsedTimer, where the deprecated methods of QTime
were used.
- Modified the tests for the deprecated methods to be enabled only
when the corresponding methods are enabled: when the deprecated
APIs are disabled, the tests will be also disabled, and the
compilation won't be broken.

As planned when adding YearRange: now that it's merged up to dev, move
it to QDateTime, since we can add to the API at 5.14.0.
This follows up on commit 82ad4be4a2.

We'll be adding calendar code here as well, and tools/ was getting
rather crowded, so it looks like time to move out a reasonably
coherent sub-bundle of it all.
