853845a4a2 Fix bugs in internal comparison operators
The comparison operators between QJsonPrivate::String
and QJsonPrivate::Latin1String weren't all correct, leading
to wrong sorting of keys in QJsonObjects when the keys were
outside of the latin1 range and resulting lookup errors.

e35841e374 Fix endianness part of QSysInfo::buildAbi() string
Both Q_LITTLE_ENDIAN and Q_BIG_ENDIAN macros are always defined
on all architectures. So, byte order detection results in
"little_endian" value for big endian systems. Test the system
endianness in a right way, according to Q_BYTE_ORDER macro
documentation.

7dce962200 Add operator-> to QJson iterators
The iterators for QJsonArray and QJsonObject are currently lacking an
operator-> definition. Unfortunately it is not possible to do in clean
way without redefining either the iterators or QJsonValueRef class.

This patch instead adds two fake pointer classes that are only used
to handle the operator-> return value.

- allows to retrieve volume for specific path and check if two or more

091653e9e7 Implement native settings format for WinRT
WinRT stores settings inside the app bundle, not in the registry.
Some tests are not fully functional due to errors in the file
implementation (See QTBUG-40588).

QSettings::SystemScope translates to a roaming container on WinRT,
meaning that settings stored inside there should be uploaded and
shared among devices. However, this is untested so far.

The tests have been updated for those platforms which do not store
the order of keys. This has been done on some locations only so
far, but needed to be done on more places for WinRT.

dcf9883dff Move the special QByteArrayList methods into QList
and make QByteArrayList be a simple typedef.

As a side-effect, the constructor taking a QByteArray is no longer
available since I couldn't find a way to add it to QList<T> when T is
QByteArray. My template-foo failed me. I tried:

 - QEnableIf<is_same<T, QByteArray>::value, QByteArray>::type
   => makes QList fail to compile for any T that isn't QByteArray
 - make the constructor a template member
   => it compiles if the parameter is a QByteArray, but not a const
      char[4] like the test was
 - inheriting constructors
   => runs into ICC and Clang bugs that I could not work around

Besides, the constructor with std::initializer_list is a superior
solution anyway.

7f78d547ca QCommandLineParser: support extremely concise option configuration in C++11
The goal of this commit to make the code in the test work:

    QCommandLineParser parser;
    parser.addOptions({
        { "a",                "The A option." },
        { { "v", "verbose" }, "The verbose option." },
        { { "i", "infile" },  "The input file.", "value" },
    });

For this, QCommandLineParser needs a version of addOption that can
take a list of options. That's what addOptions() is for.

More importantly, the QCommandLineOption ctors mustn't be explicit.
OTOH, any implicit conversion from QString or QStringList to
QCommandLineOption is also undesirable.

To solve this dilemma, add new QCommandLineOption ctors that just
take one argument and are explicit, and make the existing ctors
implicit. In order to avoid ambiguities, remove the default values
of their resp. 2nd arguments. The new ctors are by intention not
\since 5.4, as they are completely transparent to the user.

Et voila, even better than getopt_long(3).

[ChangeLog][QtCore][QCommandLineParser] Added addOptions() method.

c55aec2ed7 QFutureInterface: allow to work with a QThreadPool != globalInstance()
Background:
It is often necessary/advisable to schedule tasks on thread pools !=
globalInstance(). As Herb Sutter writes in
http://www.drdobbs.com/parallel/use-thread-pools-correctly-keep-tasks-sh/216500409
and the Qt Training Material stresses, tasks you schedule on a (global)
thread pool should be non-blocking, which currently rules out using any of
the QtConcurrent functions for, say, file I/O.

Nonetheless it's often convenient to have thread pools also for file I/O, as
the thumbnail viewer exercise in the Qt Training Material shows. In this
case, you'd use a dedicated thead pool, leaving the global thread pool for
CPU-bound tasks.

Yet, none of the QtConcurrent functions allow to pick the QThreadPool
instance on which to schedule the work created with them.

This patch prepares for them to do so.

This is the first part of the forward-port of
https://qt.gitorious.org/qt/qt/merge_requests/1281.

Implement by using a new QThreadPool* member that defaults to nullptr,
and adding setThreadPool to set this member, then using it in lieu of
QThreadPool::globalInstance() everywhere.

I chose to leave m_pool == nullptr to mean globalInstance() to avoid
creating the global instance whenever a QFuture is created, even if the
future represents the result of a calculation not run on the global thread
pool.

[ChangeLog][QtCore][QFuture] Can now be used with any QThreadPool, not
just globalInstance().

a non-existing property, is not causing a property to be added

referenced values. Such reference is supposed to not live long,
only to the first compacting or assignment.

aaaba5da24 tst_QSet: verify that {}-style initialization drops duplicates
No actual reason for this test, except my curiority. Then again, it's
good to have this check, too.

Also checks that the last entry in the init_list "wins", which is
not how std:: containers work.

8d15068911 QSettings: use QSaveFile and QLockFile to write the settings
The old unix locking code is no longer working on unix since it locks on
a file descriptor, but QSaveFile creates a new file, and as a result we
get the lock on the wrong file. Also there is no need to keep the lock
held only for reading as QSaveFile is atomic. It just needs to be held
when doing a read before writing.

As a result, since we don't hold the same lock, there could be a race
with an application running an older version of Qt if they are writing
on the same configuration file.

[ChangeLog][QtCore][QSettings] Fixed data loss while writing the config
to the disk fails.

[ChangeLog][Important behavior changes] The locking mechanism inside
QSettings has changed and is no longer compatible with the one of
previous versions of Qt. There might be corruption if two applications
running different versions of Qt are writing to the same config file
at the same time. You must also now have write permissions in the
directory containing the settings file in order to write settings

df4f334ad0 Rewrite QRingBuffer
QRingBuffer is a fully inlined class used in many I/O classes.
So, it must be as fast and small as possible. To this end, a lot of
unnecessary special cases were replaced by generic structures.

4fcd5a3da9 Make QTextStream respect QLocale with OmitGroupSeparators
The default in QTextStream is to use the C locale, so default
QTextStream are not affected. When you set a QLocale on it, the default
was to use group separators (which is the QLocale default too). This
commit makes QTextStream respect a QLocale in which the
OmitGroupSeparators option had been set.

f07c27eec1 Don't store QLibraryPrivate with empty file names in the global store
They shouldn't exist in the first place. They exist in two cases only:
1) mistake by the user in the QLibrary or QPluginLoader constructors or
setFileName

2) as a kludge for setLoadHints before a file name is set (we need to
store the user's requested hints somewhere)

This is important for the second case, as otherwise all QLibrary and
QPluginLoader objects without a file name would share the setting.
