There was a race condition between QObject::disconnect() and
QMetaObject::activate() which can occur if there are multiple
BlockingQueued connections to one signal from different threads and
they connect/disconnect their connections often.
What can happen in this case is:
T1 is in activate() method and T2 is in disconnect() method
T1 T2
locks sender mutex
selects next connection
unlocks sender mutex
locks sender mutex
sets isSlotObject to false
creates QMetaCallEvent derefs connection
posts event
Two things can happen here:
1. Connection can still be valid, but it will have isSlotObject==false
and callFunction will be used instead of slotObj
2. Connection can already be invalid
To fix it mutex unlock should be moved after QMetaCallEvent creation.
Also there is another case, when we don't disconnect but delete the
receiver object. In this case it can already be invalid during
postEvent, so we need to move mutex unlock after postEvent.

Windows with "Qt::BypassWindowManagerHint" flag can't be activated by
mouse. They can be activated only from code calling "activateWindow()"
or "requestActivate()" methods.
The patch applies also for "Qt::ToolTip" and "Qt::Popup" windows which
have implicit "Qt::BypassWindowManagerHint" flag.
The patch fixes some major issues:
- don't activate tooltips on mouse press - this causes that Qt "thinks"
that original windows loses its focus causing e.g. that text cursor
stops blinking,
- don't activate X11 tray icon - this causes that the active window
looses its focus by clicking tray icon.
The patch restores the Qt4 behavior.

This is a partial revert of a4e2f2e687ca7aec88ecf82f72d42ac61e17a5b9.
That fix tried to avoid the risk of a crash in pixel() by ensuring
Mono QImages created with external data also got a default color
table. However, that broke usable behavior in existing code that was
painting in Mono QImages using color0/color1.
This commit reverts to the old behavior, and instead expands on the
checking in pixel() so that lacking color table is handled gracefully
for all indexed formats.

Disable the scrolling optimization in QBackingStore
and fall back to repainting for non-integer deltas.
The existing rendered pixels are not re-usable in
this case.
The test is made on the delta, and not on the scale
factor. This means that user code can cooperate and
generate (logical delta, scale factor) combinations
that result in integer pixel deltas (which _can_ be
scrolled).

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).

Change e109b8a0f3c89c595f0da689e7ee847130e2ee47 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.

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.

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.

Most fields were over-written after setting invalid. The two that
weren't (not used by QUtcTimeZonePrivate) should be (if only for
uniformity with other QTimeZonePrivate variants), so set them to
sensible values.

The XML parser uses fastScanLiteralContent() to read a block of
text. The routine was not checking the range of valid characters as
defined in the XML standard:
https://www.w3.org/TR/2008/REC-xml-20081126/#NT-Char
A check has been added to stop reading the bad character.
Note that the characters are legal in XML 1.1, but QXmlStreamReader
is a well-formed XML 1.0 parser
[ChangeLog][QtCore][QXmlStreamReader]
Fixed a bug in the XML parser that prevented to load XML that
contained invalid characters for XML 1.0.

harfbuzz-ng doesn't link to Qt libraries, but uses the Qt headers for
some types. With CONFIG -= qt, we don't get QT_NAMESPACE set, which
leads to linker errors later. Instead of setting QT_NAMESPACE, ask
qversiontagging.h not to tag the headers.

it positively makes no sense to have a configure test which will be
never reached due to the configure/qmake bootstrap failing with a
slew of totally unhelpful error messages.
pre-standardization partial c++11 implementations are now rejected,
except for VS2013, which is still sufficient despite not announcing full
compatibility.

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_) {}
