07fd674740 Fix painterpath rect intersections with points on the rect
QPainterPath could in certain cases where sub-path points were on the
border of a rect fail to calculate intersects() correctly.

The patch adds handling of such cases by looking if end points cross in
or out of the rect. Other cases are already caught.

b30ce06992 iOS: Fix the shortcuts bar not correctly hidden
To avoid a compiler warning due to a wrong Apple api, a wrong
workaround was introduced. This caused the hide of the shortcuts as
expects but the visual space reserved for shortcuts was still visible
as at top with a height of ~55pixels.
While this is not important because the default virtual keyboard
is always shown, it become a problem when one want to introduce his own
virtual keyboard (UIResponder.inputView) with no shortcuts bar.
This fix really hide the shortcuts bar.

when the dbus tools are bootstrapped (which is the case in x-builds and
when above feature is disabled), they are built asynchronously to the

daeb334039 Merge the QDBusMetaType's custom information to QDBusConnectionManager
This allows us to get rid of two Q_GLOBAL_STATIC in QtDBus, which means
fewer opportunities for screwing up the order of destruction. And since
QDBusConnectionManager now ensures that the types are initialized, we
don't need to re-initialize them everywhere.

The Q_GLOBAL_STATIC for QDBusConnectionManager ensures the proper
thread-safe locking, so we don't need to lock for every type that we're
trying to register. This should make things faster.

But as a side-effect, trying to register a D-Bus metatype will cause the
QDBusConnectionManager thread to start too.

7f80c96432 Stabilize tst_QApplication::touchEventPropagation
CI metrics show that this test was flaky ~38 time in 3 days.
The problem is old: after we get a surface, a window manager can still
decide to re-position the window.
The fix is to simply send the touch event in a position where it is sure
to hit the window (usually the offset is the title bar height).

The blacklisting seems to not have worked, I could reproduce the failure
on a linux/xcb machine.

be0a221ae4 Fix missing handling of columns when merging selection ranges
This commit fixes two bugs:
1) Two ranges should not be merged if they are of different columns.
The old code would have merged (0,0) with (1, 1). Tranforming a selection
of just two indexes in a rectangle of four indexes.
2) The QItemSelectionRange appended had wrong column and worked only for
indexes of the first column. For example if 'tl' was (0, 1) than br was (0, 1)
so the QItemSelectionRange would have be ((0,1), (0, 1-1)) so ((0,1), (0,0)).
This QItemSelectionRange is invalid because topLeft columns is greater than
bottomRight column. The fix take in consideration the bottomRight column.

d517c386b2 Enable tst_qaccessibilitymac
The test was disabled because it was checking if we had the right
permissions. It does seem as if the permissions do not matter as
long as everything is in process though.
As seen by the regression in fafdb171e0
it's important to run the test. This regression would have been
caught.

50acc86804 Simplify built-in qmake install command
As the directory installation command also works with files as a source
we can unify the external commands, resulting in simpler command lines.

35f927e719 QMenu: Ensure popup() gets the right screen geometry
Many QMenu related functions end up calling sizeHint() which
does call updateActionRects(). Since we try not to update the
action rects if no action has changed, we must be careful to
call it the first time with the right screen geometry. Other-
wise, multi-display setups may get the action rects based on
the wrong display.

In QMenu::popup(), this can be solved by using the position
passed as argument. Incidentally, we were already computing
the right display geometry in the same function, only a bit
later. The updated position around an eventual push button
menu should not change the screen onto which the menu popup
will be displayed.

Tested with the multiscreen-menus manual test.

98c1d516b7 alloca: detect whether alloca.h exists
We can't depend on QT_HAS_INCLUDE for such an important functionality in
QtQml, so detect at configure time.

alloca() is not a POSIX function (it apparently first appeared in
Version 32V AT&T UNIX), so the actual header that defines it varies from
system to system. Clearly, if alloca.h exists, that's the one, so we try
it first. On most other systems that don't define it, it's in stdlib.h.
The only exception is Windows, where it's actually defined in malloc.h.
