6c5de416c9 Merge remote-tracking branch 'origin/5.6' into 5.7
Conflicts:
	src/corelib/io/qtemporarydir.cpp
One side encapsulated a repeated piece of #if-ery in a local define;
the other added to the #if-ery.  Made its addition to the other's.

	src/corelib/kernel/qeventdispatcher_unix_p.h
One side moved some members into a struct; this collided with a #undef
check that neither side now has.  Discarded the #undef part.

	src/gui/opengl/qopengltexturehelper_p.h
5.7 deleted a bunch of methods; not clear why merge got confused.

	src/tools/moc/moc.cpp
One added a name to the copyright header; another changed its URL.

When the mouse wheel step is set to "Scroll one screen",  querying
SPI_GETWHEELSCROLLLINES returns the special value unsigned(-1). Return the
default instead of converting it to int in that case since Qt does not

ad0d2f463a Cocoa integration - fix a crash in QMacPasteboard
QMacPasteboard's dtor skips LazyRequest promises and this leaves pasteboard
manager in broken state, since we release the pasteboard itself
of the next step in destructor. As a result, not only Qt's app doing D & D
(and thus via QCocoaDrag creating a stack-allocated QMacPasteboard) can die
suddenly when somebody inspects a pasteboard, this 'somebody' ... can also
die amazingly. So now we DO resolve promises using PasteboardResolvePromises
(but we also preserve the original intent of not providing or providing empty
data for lazy requests).

49926bb9ef Fix performance regression when changing fonts
Change e109b8a0f3 introduced a
performance regression when rapidly switching fonts as long as
the number of different fonts is over a relatively small number, since
the cost of fonts can be high compared to the limits set on the cache.

Since the original patch was intended to avoid exceeding the
open file limit when using Freetype on Windows, we add an
additional check on the number of engines in the cache as well
for the added, synchronous cache flush.

The limit is set to 256 to make it unlikely that it is exceeded
during a single paint event, but it can also be configured when
building Qt if a higher limit is needed.

[ChangeLog][QtGui][Text] Fixed performance regression when rapidly
switching between a large set of fonts.

b5153d5bfa Windows: Disable unsupported C++11 features with Clang-cl and ICC
Whenever someone installs Clang or the Intel compiler on Windows, it's
very likely that the compiler will be much newer than the MS headers
that came with the installed Visual Studio version. So let's make sure
we disable the C++11 features that the MS headers don't support
properly.

For example, MS's <limits> header supplied with VS 2013 doesn't mark the
max() function as constexpr, resulting compiler errors in uses of that
function in Qt code declared with Q_DECL_CONSTEXPR:

qdeadlinetimer.h(62,13) :  note: non-constexpr function 'max' cannot be used in a constant expression
        : s(std::numeric_limits<qint64>::max()), ns(0), type(type_) {}
            ^

8e4c8be0b9 Don't compile configure.exe with clang-cl.exe if cl.exe is available
Sometimes clang-cl.exe is on PATH and would get picked up by the
build. That is often by mistake, but it will inreasingly happen
as clang-cl becomes more popular. Unfortunately, configure.bat is
too early to detect which MSVC version it's set to compile
against, so the -fms-compatibility-version option will often be
wrong. One such case is when trying to build for MSVC
2013. Microsoft headers for VS2013 are unsuitable for our use in
Qt with clang-cl.

Instead, use cl.exe. It's a much better-known quantity and is
always on PATH if trying to build with clang-cl, as the latter
needs the former to fall back to if necessary.

This does not affect the build of Qt libraries and tools.

e6034a4740 Make sure JNI_OnLoad is not called more than once
Since Android 5.0 Google introduce a nasty bug[1] which calls
JNI_OnLoad more than once.
Basically every time when a library is loaded JNI_OnLoad is
called if found, but it calls *again* JNI_OnLoad of its .so
dependencies! So, JNI_OnLoad of libQt5Core.so gets called may times,
this is not a problem as long as it's called from Qt's java delegate
class loader. The problem is that the application .so file *must* be
called from default class loader to allow the user to find his custom
Activity/Service stuff.

c14c149b51 Fix QTemporaryDir to handle Unicode characters on Windows
For platforms not providing mkdtemp(), QTemporaryDir relied on an implementation
of q_mkdtemp() operating on char *, converting back and forth using
QFile::encodeName()/decodeName() when passing the name to QFileSystemEngine.
This caused failures on Windows (which uses "System"/Latin1 encoding)
for names containing characters outside the Latin1 space.

Reimplement q_mkdtemp() to operate on QString, which avoids the conversions
altogether and also enables the use of larger character spaces for the
pattern.

Add tests.

178ab88562 PathStrokeRenderer::initializePoints(): use float division
The (example) code used a real to hold 360 / 7, which is of course 51,
discarding the 3/7 that was most likely meant to be kept.  Noticed by
Coverity (CID 22364).  Use 360.0 instead of 360 to get more accurate
results.

6bb0bc73c8 QWindowsTheme: Fix the available file icon sizes
Previously, QWindowsTheme had a hardcoded list of of available file icon sizes.
As the sizes depend on the Windows display scale factor, this can lead to
undesired scaling of icons.

Maintain an array of the standard sizes against which the sizes are
matched; refresh in display change.
