1fc8e089d8 Windows: devicePixelRatio aware QWindowsTheme::standardPixmap
QWindowsTheme::standardPixmap() takes a size parameter which is in user
space coordinates. This patch causes it to calculate the size in device
pixels, to get the image from the OS in the correct resolution and to
set the devicePixelratio of the returned pixmap accordingly.

6910b8a552 iOS: Refactor text input handling to standalone responder
Instead of coupling the visibility of the virtual keyboard to
the first-responder status of the currently active QUIView, we
now treat first-responder as a separate state, tied directly
to QWindow activation. This fits better with the concept of
first-responders in iOS, as a UIView can become first-responder
without dealing with text input, eg when dealing with touch
events or menu actions.

The decision point on whether or not to show the virtual
keyboard is then handled by implementing the conformsToProtocol
method and selectively returning YES for the UIKeyInput protocol.
iOS internally calls _requiresKeyboardWhenFirstResponder on the
UIResponder to determine this, but since we can't override a
private method (like WKContentView in WebKit does) we have to
rely on the fact that the implementation of the method uses the
protocol conformance to make its decision.

Once the virtual keyboard is up, we then need to react to changes
to its configuration, such as keyboard type or the type of return
key. Normally this would be a simple call to [view reloadInputViews],
but iOS will not reload the built-in keyboards unless the UIResponder
returns YES for _requiresKeyboardResetOnReload. Since we again can't
override this private method (like WebKit does), we work around it
by taking advantage of the fact that iOS will treat any change to
the first-responder as a reason to do a keyboard reset. By using
a stand-alone UIResponder for text input we can init and destroy
these responders as needed, so that every call to reloadInputViews
will trigger a reset, as the responder has not been seen before.

We keep track of changes to the input-method-query, and detect
whether or not we need to bring up a new UIResponder for text
handling.

As part of this refactoring we now tie the visibility of the
virtual keyboard to the presence of a focus object that has
input-methods enabled. This means that we automatically will
track changes to input-elements through the focus changes,
and reconfigure or hide the keyboard as appropriate. As a
result the hide() method of QInputMethod becomes a no-op on
iOS.

b08b536f20 Windows qpa: fix minimum allowed fixed height, width on windows
A window width constraint coded in Qt4.8 was accidentally applied
to the height in Qt5. Upon further review, it does not seem that
this constraint is needed, in any case. Different versions of
Windows have different minimum window widths (8.1 had 124px
instead of 112), and setting a smaller value seems to cause no
harm.

e409eafe23 OSX: emit aboutToShow signal for top-level dock menu.
Qt sets a QCocoaMenuDelegate on every menu it creates in order to emit
the (OSX specific) aboutToShow signal. However, there are a few cases
where OSX will copy a menu without copying the delegate. One of those
cases is the dock: the result of -[NSApplication applicationDockMenu:]
is used to create a new menu, to which a few more items are copied.
This copy is then send back to the dock.

This patch invokes the delegate's -menuWillOpen: method when
-[NSApplication applicationDockMenu:] is called. Note that sub-menus
won't receive the call-back, because the dock doesn't tell the
application what happens after returning from applicationDockMenu:.

055622ed48 OS X: Fix positioning of popup menus in case of native NSWindows
The code transformed the coordinates from the view to the window's
content view, and since that content view is flipped in the pure
Qt world (content view == QNSView), it manually flipped the
coordinates to transform from that to window coordinates.

Instead just directly transform the view coordinates to window
coordinates using standard Cocoa methods, which then works with
any kind of content view and NSWindow configuration.

5b2f77c598 eglfs: Fix regression in config selection
During the introduction of context adoption support the config choosing got
broken for context creation, at least for hooks that return a customized
format in surfaceFormatFor(). The returned format is the one that needs
to be passed to chooseConfig(), not the original.

7e1e42cbf2 Android: Avoid deadlocks on suspend
Get rid of the rendezvous at shutdown: the android thread does not
need to wait for the GUI thread. Since the GUI thread frequently does
blocking calls to the android thread, this fixes several known and
potential deadlocks.

05670f586f Android: use FBO readback workaround by default.
Maintaining a black list of devices can't be reasonably done.
The workaround is now enabled by default. It can be disabled with the
QT_ANDROID_DISABLE_GLYPH_CACHE_WORKAROUND environment variable, in
which case the current list of blacklisted drivers will still be taken
into account.

d450eb5e6d Android: Guard against invalid surfaceID
Do not try to resize or destroy invalid surfaces.

This caused update problems with all GL apps after suspend,
since we would forget the dummy view that we always keep
around so we get proper transitions on shutdown.

Also make sure that we don't mess this up even if we try to destroy a
non-existing surface. This would have fixed the bug by itself, but
then we would still be stuck with the annoying warning message.
