QTimeZone("UTC") should be valid, as "UTC" appears in the list of
availableTimeZoneIds(), and tst_QTimeZone::dataStreamTest() constructs
timezones like this, which are considered valid.
The internal representation of a QTimeZone("UTC") as created by
QTimeZone::QTimeZone(const QByteArray &ianaId) is a QUtcTimeZonePrivate
which isValid(), so the containing QTimeZone isValid() too.
When QTimeZone is serialized into a QDataStream, it calls
tz.d->serialize(ds) which is QUtcTimeZonePrivate::serialize. This
writes QStringLiteral("OffsetFromUtc") followed by the IANA ID and
the offset (etc.) to the datastream.
When QTimeZone is deserialized it looks for this marker string, and if
present, it passed all of the parameters to the QTimeZone constructor
(not just the name). However, that constructor does not support standard
IANA timezones (only custom ones), and when it detects that the supplied
IANA ID is actually listed in availableTimeZoneIds(), it leaves the
pointer to the QTimeZonePrivate uninitialized (NULL), which leaves
the QTimeZone invalid (isValid() returns false).
Thus, a valid timezone which was serialized and then deserialized has
become invalid. This also affects serialization of QDateTimes with
timezones.
Fixed by calling the name-only constructor first, which works (only) for
IANA standard timezones and leaves the QTimeZone invalid (isValid()
returns false) otherwise. In which case, we can call the many-argument
contructor to create a custom timezone with the same offset as the one
which was originally serialized.
[ChangeLog][QtCore][QTimeZone] Fixed sending IANA standard UTC-offset
QTimeZones through QDataStream, which previously came out invalid after
deserialization.

Such mappings are ill-defined in the presence of daylight-savings time
(DST); at its transitions, you need information about whether DST is
active or not to determine the correct UTC value. Existing code did
not have a way to be told that hint, so could not be correct.
Fixing this required changing the (thankfully private) APIs by which
QDateTime accessed QTimeZone's information stipulated by zone time.
In QDateTime, this required propagating the needed hint, when DST
status was known.
QAndroidTimeZonePrivate overloaded QTimeZonePrivate::dataForLocalTime
with an implementation that works whenever !hasTransitions(); the base
implementation handled this case lamely, so I've moved the Android
implementation there, to have only one place for both re-writes.
Amended tst_QDateTime's expected failures; passing a date and time to
the constructor *is* ambiguous when the moment indicated is in a
transition. I have changed which way we resolve that ambiguity.
Added round-trip test of QDateTime's fromMSecs/toMSecs (but as a
QTimeZone test, since that's what's actually getting tested), based on
a test-case from Marko Kangas. Initially failed for various zones,
each at one hour-offset; and, on some platforms, for some zones, at
all offsets. These last revealed that a platform may claim to have
zone information yet, for some zones, lack it (or have very incomplete
information). In each case, despite this, the platform does give
offsetFromUtc(). (The test also found another pre-existing bug on
Linux; fixed in an earlier commit.)
To accommodate these gaps in transition data, the transition-based
code now falls back to the offsetFromUtc()-based code (used when there
are no transitions) if it can't find a previous transition (which, in
any case, it needs to do its job).

On some operating systems, tzdata files carry the Local Mean Time (LMT)
for the city in question, which better represents how time was tracked
before standard, hourly timezones were introduced in the early 20th
century. The test was asking for the data for 1653-02-09 and assumed
that it would find the first Central European Time (CET) rule, which
Germany didn't start using until 1893-04-01.
This fix allows us to remove the blacklist that had been applied to this
test without investigation. It wasn't related to OpenSUSE, aside from
the fact that OpenSUSE tzdata carries the LMT data.

Previously WinRT was using the UTC backend which fails on all platforms
for some QDateTime autotests related to timezone items. Hence switch to
the Windows implementation for WinRT as well.
However, the windows backend does query the registry heavily, which is
not supported on WinRT. Instead use the API version provided by the SDK.
Long-term we might want to switch to this version on desktop windows as
well, as direct registry access would not be required and we could
harmonize the codepaths for both platforms.

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.
