f48a76bbbf Revert "Fix compilation with icc, converting between egl's and gl's Error types"
The patch causes an Assert on close and thus cannot be used as is. I do
not have ICC available to try to come up with an alternative solution so
the patch is reverted for the time being.

This reverts commit 93a78799c3.

c808a6978b Add a means to handle dynamically created qmldir files
This will enable modules like QtWebView which needs to generate its
qmldir at qmake time since it changes depending on whether QtWebEngine
is available or not. This ensures that it is not created in the sources
directory and in the build directory and correctly picked up.

2bafd997ee Don't quit when last QWindow is destroyed, wait for it to close
Destroying windows happens independently of closing them, e.g. when
a window is moved from one screen to another non-sibling screen.

The logic for quitting the application should apply to the actual
closing of a window, as documented.

01e1df90a7 Move screen maintenance functions from QPlatformIntegration to QWSI
QWindowSystemInterface is the de facto API for any plumbing going from
the platform plugin to QtGui. Having the functions as protected members
of QPlatformIntegration was idiosyncratic, and resulted in awkward
workarounds to be able to call the functions from outside of the
QPlatformIntegration subclass.

The functions in QPlatformIntegration have been left in, but deprecated
so that platform plugins outside of qtbase have a chance to move over to
the new QWSI API before they are removed.

1320b2f644 Fix memory leak when unregistering a gesture recognizer
When a gesture was unrecognized, then it would add itself to the
obsolete gestures hash. This was cleaned up only on application exit,
but as the unregister call happens whenever a widget that had registered
gestures was deleted then the hash could grow quite considerably.

In order to ensure the original intention of the code here, we only
call unregisterGestureRecognizer() when there is a QGestureManager in
place to call it on. Otherwise it would create a memory leak in itself.

37b154858f Improve configurejson2cmake feature output generation
There were a few cases of feature outputs that were handled
incorrectly before this change, specifically:
- publicFeatures and privateFeatures with custom names
- privateFeatures that also ended up writing defines into
  public headers
- publicFeatures that ended up in private headers
- internal features (that should have no QT_FEATURE_foo
  defines) that were still written to either public or
  private headers

The change takes care of all those cases by keeping a map
of which features need to be written along with any visibility
specifications, as well as custom name changes.

e5b2699750 Do define generation after feature evaluation
Instead of generating defines guarded by feature ifdefs,
record the define information (condition, name, value, etc),
and generate the final define statement only if the feature
condition evaluated to true.

This removes the need to generate feature defines
(QT_FEATURE_foo) for features that have neither public nor
private outputs in the configure.json file.

Also note that all qt_feature_definition() calls
(which correspond to type:"define" outputs in json files)
now generate defines only in the public header, which seems
to be consistent with how qmake evaluates json files.

11228e54b6 wasm: fix touchpoint handling
emscripten sends a touchstart event for every touch point when a new
touch point happens, so this makes them moved or stationary if already
known.

This allows QtQuick PinchArea to work.

77a4915bf9 macOS: Add IOSurface based backingstore for layer-backed views
The naïve approach used for layer-backing in the past caused a detach
of the backingstore QImage on each beginPaint, since the image was
assigned to the layer via a CGImageRef that participated in the
QImage implicit sharing (and had to, so we couldn't get around that).

We now use IOSurfaces, wrapped in a QPlatformGraphicsBuffer abstraction.
The surfaces can be assigned to the layer's content the same way images
could, but allows us to reason more closely about whether or a buffer
is in use, and increases the chance that we will have a zero-copy path
to the screen.

Unless the window has requested a surface format with single buffering
we use a dynamic swap chain of buffers. In most situations there will
be two buffers in play, one assigned to the layer and one ready to
paint to, but during resize and some other situations the buffers
will grow temporarily to accommodate the increased back-pressure.

Since QBackingStore is documented as having single-buffer behavior,
we take care to persist content between the buffers before every
swap. By doing this before swapping, instead of before each paint,
we can avoid preserving areas that will be painted to anyways, and
will in many situations (such as blinking cursors e.g.) end up not
persisting anything.

The RasterGL surface case is handled by reading out the buffer data
and doing a manual texture upload. In the future we can support
direct texture access via CGLTexImageIOSurface2D, but this requires
QPlatformBackingStore::composeAndFlush to learn how to support other
targets than GL_TEXTURE_2D, as CGLTexImageIOSurface2D only works with
GL_TEXTURE_RECTANGLE_ARB targets.
