edfce46a6c Update the Unicode Data and Algorithms up to Unicode 6.3.0
* Mongolian and Phags-pa characters have been given a Joining_Type
  classification for contextual shaping. As a part of these additions,
  one Phags-pa character has the Joining_Type value of L (Left Joining),
  which no character had been assigned before.
* The unassigned code points in the Currency Symbols block have been
  given the Bidi_Class property value ET and the Line_Break property
  value PR, to help implementations support new currency symbols,
  when they are encoded.
* Hebrew letters and basic punctuation marks have been assigned
  the newly introduced Word_Break property values Hebrew_Letter,
  Single_Quote, and Double_Quote.
* The Bidi_Class property has been extended with four new values
  for directional isolates.
For more details, see http://www.unicode.org/versions/Unicode6.3.0/

eaedc04d90 Autotest: Fix QDateTime failure if the test got run West of Greenwich
There was a comment about the test failing for max() because of an
overflow. That happens if you're at UTC or ahead of it (to the East of
the Prime Meridian), which is how this test usually gets run (UTC,
Europe/Oslo, Europe/Helsinki, Pacific/Auckland). But if you're behind
UTC (to the West of the Prime Meridian), then the overflow happens for
min().

ee7536876c Add the UTF16-to-Latin1 in-place converter
This is only possible for two important reasons:

1) QString and QByteArray d pointers are both done with QArrayData and
   that class does not care that the alignof(T) changes from 2 to 1,
   so we can give the pointer from QString to QByteArray
   (after adapting the allocated size, which is now double)

2) conversion from UTF16 to Latin1 always has fewer bytes (exactly half)

3e803b5180 QCollator: enable move semantics
This necessitates adding d==0 checks in QCollator. By documenting that
moved-from instances can only be assigned to or destroyed, we can
limit the functions in which to check for d==0 to the assignment
operator and the destructor.

Doing otherwise would destroy all advantages of move semantics by
introducing a heap allocation to re-populate other.d.

Add a test for this (QCollator didn't have any before).

475cbed244 QDateTime - Fix round-trip of second occurrence times
At the Daylight Tme to Standard Time transition, the local time repeats
itself, i.e. 2am occurs twice. Qt's behavior when setting this using
the local time is ambiguous, as it depends on the system implementation
of mktime, which behaves differently on different platforms.  Currently
this behavior remains undefined.  When setting using an msecs or time_t
value however we can determine the correct instance to use and cache it
to ensure that any conversion back from local time to msecs is performed
consistantly on all platforms.

Note that caching this value will result in any calculations being wrong
should the system time zone change, or its rules change.  This will be
fixed in Qt 5.3 when the system time zone change signal is implemented
and QDateTime switches to using QTimeZone instead of mktime to provide
consistnt behavior across platforms.

The QTimeZone spec does not require this fix as it already caches the
correct offset in setMSecsFromEpoch().

Mac uses the CLDR format codes which need to be translated into their

This change updates support to the latest version of CLDR, fixes the
treatment of years, and defaults to ignoring any new format codes
added in the future.

Note that this change cannot have auto tests written as the system
locale formats change between versions of OSX.  Testing must be
done manually by changing system locale and formats.

48e2c3ac33 QTimeZone - Define new class and api
Implement the new QTimeZone class based on the Olsen Time Zone ID's.

This is the base implementation and does not include the Platform
backends which are implemented separately.

This change does include a default UTC backed to be used if no Platform
backend is available, i.e. if QT_NO_SYSTEMLOCALE is set and ICU is not
configured.  This backend also provides a default set of time zones in
the standard "UTC+00:00" offset format that are guaranteed to always
exist regardless of the Platform backend.

This change includes conversion functions between the Olsen ID's and
Windows ID's using a conversion table based on Unicode CLDR data.
This is implemented for all platforms for scenarios such as a Linux
program needing to communicate with a Windows Exchange Server using
the Windows ID.

The CLDR conversion table is included under the UNICODE license, see
http://unicode.org/copyright.html for details.

[ChangeLog][QtCore][QTimeZone] Added new QTimeZone class to support
time tone calculations using the host platform time zone database
and the Olsen time zone ID's.

to toCFString() and toNSURL(). These attributes assists
the clang static analyzer. Add Q_DECL_ helper macros
to qcompilerdetection.h.

Add test functions (in _mac.mm files) to the QString
and QUrl tests. Split out the test class declarations
into a separate headers files.

8d6ee59948 QDateTime - Add api for isDaylightTime()
Add new method to return if the current time is Daylight Time.

[ChangeLog][QtCore][QDateTime] Added new method isDaylightTime() to

7b07c3ff78 QDateTime - Fix Daylight Transition for "missing" hour
When Daylight Time transtion goes from Standard Time to Daylight Time
there is a "missing" hour, i.e. at 2am CET the clock goes forward to
3am.  Currently QDateTime ignores this gap and considers the time to be
valid and able to be manipulated.  This change respects the transition,
so any time set in the missing hour is considered invalid, and any date
maths returns valid results.

The validity in the current time zone needs to be checked every time
isValid() is called in case the system time zone has changed since the
last time it was checked. This is done by calling mktime to check the
returned result matches the expected result.  This could be very
inefficient, but the returned offset value is cached each time so
mktime is not required to be called again within each method call,
effectively meaning mktime is called the same number of times by
each method. Note that this means any new methods added must be
careful to ensure either isValid() or refreshLocalTime() is called
first by any method needing to use the UTC value.

[ChangeLog][QtCore][QDateTime] The Standard Time to Daylight Time
transition for Qt::LocalTime is now handled correctly.  Any date set
in the "missing" hour is now considered invalid.  All date math results
that fall into the missing hour will be automatically adjusted to a
valid time in the following hour.

18322bfabc QDateTime - Change date/time storage to msecs
Change from storing the date and time as QDate and QTime to a serialised
msecs format.  This format is a direct translation of the QDate and
QTime values, it is not the actual msecs since the Unix epoch.  This
msecs format ensures we are always able to recreate the original QDate
and QTime values, but should still simplify the code and improve
performance.

Because we no longer store the explicit date and time we need to store
their isNull()/isValid() status separately.

The changes in storage results in the same memory footprint as before.

Note that this change does not optimize the code nor set out to fix the
known bugs, it only seeks to maintain the current behavior, although
some bugs are fixed implicitly.  More bug fixes and optimizations will
follow.

[ChangeLog][Important Behavior Changes] The supported date range in
QDateTime has been reduced to about +/- 292 million years, the range
supported by the number of msecs since the Unix epoch of 1 Jan 1970
as stored in a qint64, and as able to be used in the
setMSecsSinceEpoch() and toMSecsSinceEpoch() methods.

e76c312eb8 QDateTime - Switch to using msecs based functions
A number of QDateTime functions directly use or modify the data stored
in the private, but future changes to store msecs and status make this
maintenance more complicated.  Where possible simplify this code to use
the standard msecs functions, standard constructors, or public api
instead.  This greatly simplifies the functions and the following msecs
storage code changes.

This is an intermim step towards storing the time in msecs.  Some
functions will be slower as a result of this change, optimization
will take place after all the msecs changes are completed.

Note this also removes a test that used valid QDates outside the range
of msecs, this change in behavior will be documented in the final
mscs change.
