356f5bbac3 Cocoa: Make child window cursors work correctly
The existing cursor logic had a couple of issues:

- It made the faulty assumption that we could not use
the NSWindow invalidateCursorRectsForView API for
child NSViews.

- It used NSWindow invalidateCursorRectsForView and
NSView resetCursorRects. This API has been replaced
by the more general NSTrackingArea API.

- It did not implement falling back to the parent
window cursor if the current window has no cursor
set.

Document that QWindow cursors work the same way as
QWidget cursors in that a QWindow with no set cursor
will fall back to the parent window cursor.

Change the cocoa platform code to use NSTrackingArea
exclusively and implement NSView cursorUpdate which
sets the cursor. Handle immediate change on QWindow::
setCursor() manually.

Add QWindow::effectiveWindowCursor() and
applyEffectiveWindowCursor() which finds the correct
window cursor.

Add a manual test for the child window, child widget,
and QWidget::createWindowChild cases.

e70e168abb Plug leaks in tst_QWizard
This completely over-engineered piece of code has a hierarchy of
Operation subclasses encapsulating but three actual operations
on a QWizard.

Because these operations and their containers were all allocated
on the heap, but never deleted, asan went crazy and reported over
50 leaks (not the record so far, but a (distant) second).

Since these collections are passed through addColumn/QFETCH, too,
it's nearly impossible to track their lifetimes. So instead of
trying, delegate that to the runtime, ie. pack the Operation
objects into QSharedPointer and pass around those instead.

0e888ae1a1 tst_QGraphicsItem: plug remaining leaks
Store QGraphicsItems that are either not added to a scene or
removed from it again and that are also not children of other
items - iow: those that were leaked, even on successful runs
of the tests, in either a QScopedPointer, or, where that'd
cause too much churn due to adding of .data() calls, back the
pointer by a stack-allocated object.

This fixes the remaining leaks reported by GCC 6.2.1's ASan on
successful runs of tests/auto/widgets/graphicsview/qgraphicsitem.

4cb614c7ab Apple OS: Handle QSetting strings with embedded zero-bytes
Saving strings with embedded zero-bytes (\0) as CFStrings would
sometimes fail, and only write the part of the string leading
up to the first zero-byte, instead of all the way to the final
zero-terminator. This bug was revealed by the code-path that
falls back to storing e.g. QTime as strings, via the helper
method QSettingsPrivate::variantToString().

We now use the same approach as on platforms such as Windows
and WinRT, where the string produced by variantToString() is
checked for null-bytes, and if so, stored using a binary
representation instead of as a string. For our case that
means we fall back to CFData when detecting the null-byte.

To separate strings from regular byte arrays, new logic has
been added to variantToString() that wraps the null-byte
strings in @String(). That way we can implement a fast-path
when converting back from CFData, that doesn't go via the
slow and lossy conversion via UTF8, and the resulting QVariant
will be of type QVariant::ByteArray. The reason for using
UTF-8 as the binary representation of the string is that
in the case of storing a QByteArray("@foo") we need to
still be able to convert it back to the same byte array,
which doesn't work if the on-disk format is UTF-16.

cd1d114140 Unset qgl_current_fbo when the default FBO is bound
Previously when a new QOpenGLFramebufferObject was bound, the
QOpenGLContextPrivate::qgl_current_fbo member was also updated to point
to this new object.
But if a user called QOpenGLFramebufferObject::bindDefault(),
qgl_current_fbo was not unset, meaning that if the FBO object would be
deleted at some point, qgl_current_fbo would be a dangling pointer.

This patch makes sure to clear the value of qgl_current_fbo when
bindDefault() is called. It is cleared, and not set to point to another
object because the default platform OpenGL FBO is not backed by a
QOpenGLFramebufferObject.

5cc0d92c24 QAbstractItemView: use only a 1x1 QRect for selecting on mouse press
Before commit f1e9076809, mousePressEvent
called the virtual method setSelection(const QRect&, SelectionFlags)
with the 1x1 rectangle which contains only the clicked QPoint, unless
the SelectionFlag "Current" was set because Shift was pressed during
the mouse press.

Since that commit, the behavior has been changed such that the
rectangle is the one that is spanned by the center of the clicked item
and the clicked pixel. In theory, the result should be the same (i.e.,
only the clicked item should be selected), but

* the code path in QListView::setSelection for 1x1 QRects is more
  efficient, and
* using a larger QRect can cause problems with custom views, see the
  comments in QTBUG-18009

This commit ensures that the 1x1 QRect is used again, unless the
SelectionFlag "Current" is used.

462f6029ed Fix crash when doing many text layouts with superscript/subscript
After e109b8a0f3, it is possible
that the cache will be flushed as a result of inserting a new
font rather than just when the timer event triggers. When doing
superscript and subscript text layouts, we would first get
a regular font engine, then a scaled one, and then reference
the regular font engine *after* getting the scaled one. If the
regular font engine was deleted as a result of inserting the scaled
one, we would get a dangling pointer and crash.

The situation was improved by 49926bb9ef.
You would now to switch between 256 different fonts in the layout
in order to trigger it. The test in the commit will trigger the
crash even with this change.

[ChangeLog][Qt Gui][Text] Fixed a crash that could happen if you
were doing many different text layouts with different fonts
and superscript or subscript alignment.

The alternative would have been to create this once, as a member

5571d2bf62 tst_QApplication: Fix UBs (invalid cast) in focusMouseClick()
Found by UBSan:

  0x7ffda11f2220: note: object is of type 'QMouseEvent'

The code attempted to model the layout of a QEvent with another class
that allows public access to the memory location that (hopefully)
corresponds to QEvent::spont, gaining access by casting a QEvent
object to that specifically-crafted class.

Fix by the using the existing QSpontaneKeyEvent::setSpontaneous()
call, which, despite its name, works for all QEvent subclasses, and
which has already been fixed to not invoke UB (in bc087db).

3379ace11b QDateTimeEdit: synchronize time-spec before initializing display
QDateTimeEdit ignores the time-spec of its date-time value, using its
own time-spec instead; mostly, this works because it first conforms
the value to its own time-spec.  However, during construction, before
doing this, it set up its display data, which could leave it with a
different time (rather than a different representation of the given
time) than it was asked to use.

Moved the updateTimeSpec() calls to immediately after setting value in
QDateTimeEditPrivate::init() to ensure correct handling.  Added test.

158781ff25 QSslSocket: respect read buffer's max size (SecureTransport)
1. QSslSocketBackendPrivate::transmit was ignoring 'readBufferMaxSize';
as a result, we can have a user trying to set read buffer's size

potentially growing its internal buffer to a huge size. This also
results in auto-tests failing - whenever we're trying to limit read

25c9a6c9b4 QtWidgets: Fix enter/leave events on popup menus
If the sloppy menu popups - send the leave event to the last active
menu (except Cocoa), because only currect active menu gets enter/leave
events (currently Cocoa is an exception).

Check that the menu really has a mouse before hiding the sloppy menu -
don't rely on enter events.

This patch removes some unnecessary synthetic mouse enter/leave events
from QMenu which causes event duplications with different mouse cursor
position.

Refactor sloppy menu timer handling - start or restart timers on mouse
move events. Enter/leave events are not reliable.

Fixes:
- better enter/leave events handling for native widget actions,
- reduce duplicated enter/leave events for menu actions,
- better handle torn off sloppy menus.

3370ab9119 Never return char variants when reading prepared MySQL statements
This has undesired effects when converting a QSqlRecord to JSON.
A char(0) e.g. has special semantics that are undesired when
reading a Tinyint column.

I don't think that returning bool for the special case of a
Tinyint(1) is required. This also did not happen before, and
is also not happening when not using a prepared statement.
Instead, a plain int/uint QVariant is returned.

This patch extends tst_QSqlQuery::integralTypesMysql to also
cover reading and writing booleans from/to a MySQL table column
of type Tinyint(1). Additionally, the reading is now also done
with a prepared statement and we also check the raw variant
value.

The broken behavior fixed by this patch was introduced by me in
commit 194403a348.

3b8df0ea44 QtWidgets: Send show/hide event to children on restore/minimize
Child widgets should get the show/hide event when the TLW changes its
state, because child widgets are also visible or invisible. This
restores the Qt4 behavior (fixes the Qt4->Qt5 regression).

Restoring/minimizing the TLW now sends the spontaneous show/hide event.

Show events are now handled also in the expose event handler in the
QWidgetWindow class, because the show event must occur before the
expose event to avoid possible flicker e.g. the OpenGL content. This
can happen e.g. on XCB platform. If the "WindowStateChange" event occur
before the expose event (e.g. Windows platform) then the code in expose
event handler will be ignored to prevent event duplications.

Added autotest.

2a6bea7a55 qcompilerdetection.h: retract Q_COMPILER_DEFAULT_MEMBERS for MSVC < 2015
Earlier versions of the compiler cannot default
move special member functions, even though we
also define Q_COMPILER_RVALUE_REFS for them.

Fix by retracting the less-often-used of the
two compiler feature defines.

Q_COMPILER_DEFAULT_MEMBERS is not used outside
QtBase in neither 5.6 nor 5.7 (5.8 is not
released at this time, so wasn't considered).
The same is true of the dependent macros
Q_COMPILER_DEFAULT_DELETE_MEMBERS and
Q_DECL_EQ_DEFAULT.

In QtBase, the three uses are:
1. in QAtomic*, where the user also requires
   Q_COMPILER_CONSTEXPR, which is not defined
   for any MSVC at this time,
2. for QEnableSharedFromThis, which is a class
   template with an alternative {} implementa-
   tion of the default constructor, and uncon-
   ditional user-defined copy special member
   functions.
3. The test of the corresponding functionality
   in tst_compiler, which this commit amends.

That means that neither of these two only uses
of the macro in Qt libraries are affected by
the change.

The reason we do this change, then, is that in
the future, we want to be able to more easily
restore move special member functions for
classes for which they are suppressed due to
user-defined dtors or copy special member
functions.
