Since its initial implementation, QRingBuffer had the following
fragilities in the architecture:
- it does not guarantee validity of the pointers, if new data will
be appended. As an example, passing an address of the QRingBuffer
chunk as a parameter to the WriteFileEx() function on Windows
requires the stability of the pointer. So, we can't add new data
to the QRingBuffer until the overlapped operation completed
(related issues were fixed for QWindowsPipeWriter and QSerialPort
in 5.6 branch by introducing an intermediate byte array);
- inefficient reallocations in reserve(), if a shared chunk was
inserted in the queue (we can get a reallocation in the place
where we don't expect it:
char *writePtr = buffers.last().data() + tail; <- line #133
).
Proposed solution is to avoid reallocation by allocating a new
block instead. That was accomplished by introducing a QRingChunk
class which operates on a fixed byte array and implements head/tail
pointers strategy for each individual buffer in the queue. So,
QRingBuffer is no longer dependent on QByteArray's internal
shrink/growth algorithms.

Commit 68bcccac took account of MS TZ APIs mis-describing non-DST
zones making changes to standard offset (e.g. Europe/Samara in 2011 at
the end of October); however a DST transition that coincides with an
equal and opposite change to standard offset, while the other end of
its DST period changes normally, ends up looking exactly the same
(although it's nominally subtly different), in MS's APIs. Thus fixing
the more common case broke this more obscure case; there is no way to
fix this (other than not using MS's broken-by-design APIs). So kludge
the test to skip the bit we know this breaks.

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.

The QString API symmetry test strikes again, showing that this is
inconsistent with both QString and QByteArray, which both return empty
for empty inputs.
The fix actually makes the implementation simpler.
Extend the QStringRef test to cover null inputs, too. I can't merge
the trimmed() test in the API symmetry test until everything is
actually consistent.
[ChangeLog][QtCore][QStringRef] trimmed() now returns an empty
string-ref for an empty input. Before, it would return a null one.

qstrcmp sorts null strings before empty ones, while the Qt string
classes consider them equal.
The qt_compare_strings() overload for QLatin1String was using
qstrcmp(), but is supposed to implement the semantics that Qt string
classes use, so we need to add an extra check.
Was uncovered by tests for QLatin1String::startsWith(), but added a
new test for qCompareStrings() now, which is a bit more complicated
than desired, due to the lack of QUtf8String.

Since commit bf2160e72c, we can rely on
charNN_t support in all compilers except MSVC 2013, and since that
commit, we use (in 5.10, not 5.9, yet)
!defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS)
when we only need charNN_t, the type, as opposed to its library
support (u16string, char_traits<char16_t>, ...).
This patch splits the Q_C_UNICODE_STRINGS macro into two, adding
Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving
Q_C_UNICODE_STRINGS for when we need just charNN_t support.
In QDebug, when constructing a QChar out of a char16_t, cast to ushort
first, since QChar(char16_t) was only officially introduced in Qt 5.10.
[ChangeLog][Potentially Source-Incompatible Changes] The internal
Q_COMPILER_UNICODE_STRINGS macro is now defined if the compiler
supports charNN_t, even if the standard library does not. To check for
availability of std::uNNstring, use the new Q_STDLIB_UNICODE_STRINGS
macro.

We have two functions to get a substring without doing some
calculations involving size():
- mid(p): mid(p, size() - p)
- right(n) : mid(size() - n, n)
(left does not involve size(), so isn't in that set). What was missing
was a name for
- f(n): mid(0, size() - n)
As an action, it's called chop(), so call the transformation version
chopped().
I made chopped(n), n < 0 or n > size(), undefined, because QString(Ref)
::left() is broken[1], while the QByteArray implementation is not. This
is the only way to get consistent behavior among the three classes.
I's also the correct thing to do.
[1] instead of returning the empty string for negative indexes, it
returns the whole string.
[ChangeLog][QtCore][QString/QStringRef/QByteArray] Added chopped(n), a
const version of chop(n).

Like the qt_compare_strings()/qCompareStrings() split, distinguish
between the internal and exported functions.
Because of the circular dependency between qstring.h and qvector.h,
the inline toUcs4() function has to be in qvector.h.
At some point, we need to refactor the headers so qvector.h is lower
in the dependency chain than qstring.h. It's not the first time this
bites.

Akin to the successful tst_QStringApiSymmetry, add such a test for
generic containers, too. Yes, we have tst_collections, but it's a
cut'n'paste mess that makes it hard to systematically perform
cross-class checks for consistency. This new test, still in its
infancy, uses templates and thus ensures that exactly the same checks
are run on all containers.
Starting out with front()/back(), which the string classes were found
to lack, we will build this test up, as we did and continue to do with
the string API one.
