Olivier Goffart 6797570a59 Fix UB in QFutureInterface: invalid casts from ResultStoreBase to ResultStore<>
ResultStore never actually exists, only ResutStoreBase does. So casting to
ResultStore<T> and calling its  member functions is UB. Put the type dependent
function as template member functions within ResultStoreBase and so we don't
need QtPrivate::ResultStore anymore.
Same goes for the iterator.

Marc Mutz 9c016cefe9 QFuture(Interface): remove unneeded special member functions
The compiler-generated ones are just fine.

This is BC because the class is not exported and
QFutureInterfaceBase (needlessly) contains virtual
functions (the dtor), so this class will never be
trivially copyable. It's also not movable, until I
figure out how to add move special member functions
to QFutureInterfaceBase.

Also made the QFutureInterface(State) constructor
explicit, because a State is not a faithful
representation of a QFutureInterface.

Jani Heikkinen 1a88b2f768 Updated license headers
From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/

Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

Jani Heikkinen 83a5694dc2 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

Marc Mutz 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().

Axel Waggershauser b11317a643 Whitespace cleanup: remove trailing whitespace
Remove all trailing whitespace from the following list of files:
*.cpp *.h *.conf *.qdoc *.pro *.pri *.mm *.rc *.pl *.qps *.xpm *.txt *README
excluding 3rdparty, test-data and auto generated code.

Note A): the only non 3rdparty c++-files that still
have trailing whitespace after this change are:
* src/corelib/codecs/cp949codetbl_p.h
* src/corelib/codecs/qjpunicode.cpp
* src/corelib/codecs/qbig5codec.cpp
* src/corelib/xml/qxmlstream_p.h
* src/tools/qdoc/qmlparser/qqmljsgrammar.cpp
* src/tools/uic/ui4.cpp
* tests/auto/other/qtokenautomaton/tokenizers/*
* tests/benchmarks/corelib/tools/qstring/data.cpp
* util/lexgen/tokenizer.cpp

Note B): in about 30 files some overlapping 'leading tab' and
'TAB character in non-leading whitespace' issues have been fixed
to make the sanity bot happy. Plus some general ws-fixes here
and there as asked for during review.
