Johan Klokkhammer Helsing f08038fca7 Remove deprecated QGL* classes
Removes QGL paths in sub-attaq and chip examples.

The boxes example depended on QGL and has been removed.

The corresponding module and test directories for the opengl module are now
empty, but has been left there so we can move the QOpenGL* classes there.

[ChangeLog][QtOpenGL] The deprecated QGL* classes have been removed.

Thiago Macieira 746ab4bbd6 Inline the size and data pointer members in QString
I'd have preferred to use QArrayDataPointer<ushort> for QString, but
that option wasn't the best one. QArrayDataPointer try to do some
operations using QArrayDataOps and that would expand to unnecessary
code. What's more, the existing code expected to be able to modify and
access the d pointer.

Instead, this commit introduces QStringPrivate (named differently from
QStringData to catch potential users), which contains the three
members. This POD class is also used in QJsonValue to store the
"inlined" QString. QHashedString in qtdeclarative will need a similar
solution.

Thiago Macieira a3aa2fcfa7 Introduce the Mutable flag and move QArrayDataPointer::needsDetach
The Mutable flag now contains the information on whether the data this
QArrayData points to is mutable. This decouples the mutability /
immutability setting from the allocation and from the type of data,
opening the way for mutable raw or foreign data.

There are still plenty of places in the source code that check the
size of the allocation when it actually wants d->isMutable(). Fixing
this will require reviewing all the code, so is left for later.

The needsDetach() function is moved to QArrayData and
de-constified. It returns true when a reallocation is necessary if the
data is to be modified.

Thiago Macieira f6a151024b Introduce flags to indicate the QArrayData type
These flags allow us to determine what type of data QArrayData is
carrying. There are currently only two supported types:
 - raw data type: constructed via fromRawData or static data
 - allocated data type: regular data done via heap allocation

The QArrayData object is usually allocated on the heap, unless its own
reference count is -1 (indicating static const QArrayData). Such
object should have a type of RawDataType, since we can't call free().

Add GrowsBackward for completeness as well as the StaticDataFlags
default for static data.

There are a few cases where d->alloc was replaced with a better
alternative, like d->size. The one case that remains in the code will
be replaced by a different test when it's available.

Paul Olav Tvete 5a6fb46488 QGraphicsItem: Fix mouse tracking with modal panels
This fixes the case where a mouse tracking item is added to the
scene while a modal panel is blocking. In order to optimize event
delivery, mouse tracking is enabled for the view only when an
item that needs it is added. This means that we cannot use
itemAcceptsHoverEvents_helper(), since that returns whether the
item _currently_ needs hover events, and we need to know whether it
will need them in the future.

[ChangeLog][QtWidgets][QGraphicsView] Fixed a bug where hover events
would not be delivered if the item was added while blocked by a modal panel.

Paul Olav Tvete 913146ccd4 RHI: new native texture API
The new version takes/returns a value that can be unpacked and passed to
other functions without knowing which backend is in use.

The old API will be removed in a later change when dependent modules have
been updated

Since the operator does not have a total order, it is kind of pointless,
and this is going to be removed in Qt6
