53e6cb3ff6 Fix the gregorian date <-> julian day calculations in QDate
The old code is just plain wrong for negative julian days. Replaced
with plain math from The Calendar FAQ [1], which is correct for all
julian days, provided you use mathematical integer division (round to
negative infinity) rather than c++11 integer division (round to zero).

[1] http://www.tondering.dk/claus/cal/julperiod.php

While the conversion code works for up to around JD +/- (2^63/4), we
only use an int for the year in the API, so this patch limits minJd()
and maxJd() to 1 Jan (2^31) BC and 31 Dec (2^31-1) AD, respectively.

Note that while the new conversion code looks like it would be more
expensive than the old, gcc will in fact be able to optimize it to be
slightly faster (probably because x86 hardware implements round to
negative infinity, and so GCC manages to optimize floordiv to a single
instruction, compared to the three instuctions needed for operator/).

In the following test application, run with a release mode Qt and
redirecting stderr to /dev/null, I measured an improvement from
6.81s +/- 0.08s to 6.26s +/- 0.16s user time over five runs on an
otherwise idle x86_64 system.

int main(int, char *[])
{
    int year, month, day;
    qint64 jd;
    for (qint64 i = Q_INT64_C(-1048576) ; i < Q_INT64_C(1048576); ++i) {
        QDate::fromJulianDay(i).getDate(&year, &month, &day);
        jd = QDate(year, month, day).toJulianDay();
        qDebug() << jd << year << month << day;
    }
}

6a7a08b4a8 Improve QDate test coverage.
Some statements could not be tested, such as default cases of switches
where all possible cases are already handled and some statements where
the system locale is used.

I also removed some statements that would never be reached and hence
will never be able to be covered by tests.

f29896840c Handle invalid dates properly for QDataStream versions < 5.
In Qt 5, when streaming an invalid QDate using a QDataStream version
earlier than Qt_5_0, QDate.jd is written and read as 0, which is an
invalid julian day for Qt versions earlier than 5.0. For Qt 5.0
however, 0 is a valid julian day, so when comparing a deserialised
invalid date (read using a QDataStream version < Qt_5_0) against a
default-constructed invalid date, they won't compare equal when they
should.

672b5b7ab6 Set the Qt API level to compatibility mode in all tests.
Qt 5.0 beta requires changing the default to the 5.0 API, disabling
the deprecated code. However, tests should test (and often do) the
compatibility API too, so turn it back on.

8327fa7c11 QDateTime: Store Julian Day as qint64
Store the QDate Julian Day number as an qint64 instead of uint32 to
enable support for dates before 2 January 4713 BCE.  This changes the
possible date range to be approx 2.5 Quadrillion BC to 2.5 Quadrillion
AD. A qint32 was not used as it only covers 5 million BCE to 5 million
CE which does include Geological or Astronomical time.

The effective supported date range is currently 4800 BCE to 1.4 million
CE due to restrictions in existing conversion formulas.  The effective
range will be extended later with new formulas.
