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.

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).

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().

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.
