Now that more of the raster operations are NEON-optimized this should
be acceptable. The switch enables antialiased drawing, and makes iOS
in line with other platforms in having QBackingStore backed by a QImage.
The use of QImage also allows us to remove code from the backingstore
implementation that was only needed to support the composeAndFlush
code path.
The common parts of a raster backingstore implementation have been
factored out into QRasterBackingStore in platformsupport, which can
be shared with more platforms in the future.
[ChangeLog][iOS] QBackingStore now uses the raster paint engine

1. Keep 'separator' a QLatin1String.
- saves at least two memory allocations
- necessitates carrying the \n previously prepended to it
around explicitly
2. Start adding to 'textToCopy' with op+=
- saves one allocation, costs one -> ±0
- preallocates more capacity than if we started with
assignment
3. Collapse three unconditional op+= into one
- more efficient usage of QStringBuilder
4. Don't collect button texts in a separate variable, but
append to 'textToCopy' directly.
- saves at least one memory allocation, probably more
since the growth increments of 'textToCopy' should
be larger (due to more content) than those of a new
variable.
Also replace index-based iteration over the buttons with
C++11 range-for over a const QList. Avoids the detach that
happened previously, due to use of op[] instead of at(),
but frankly, I was just too lazy to separate this change.

When a QLineEdit is readonly there's a discrepancy between key press
events and shortcut override events. For instance, presses Ctrl+C
copies the text unless there's also a shortcut for the same key sequence.
In this case, the shortcut override event is not handled, and no text
is copied. Fix it by splitting the handling of shortcut override
events between "read only" access (copy, select, etc.), which still
makes sense on a read only line edit, and write access (paste, ...)
which doesn't.

The documentation says that we scroll one pixel, but changing the
behavior in 934f062203 to do that
was not well received.
People were relying on the undocumented behavior - and the new behavior
was considered to be a regression. (Nobody called setSingleStep since
Qt in many cases provide a reasonable singleStep - which implied that their
programs scrolled with 1 pixel which was quite slow). Furthermore getting
the old behavior (auto set of single step) was nearly impossible.
However the revert (done in 0e69230d02)
gets us back to QScrollbar::setSingleStep not working in pixel scroll mode
(even without it being documented - but we should also have a working API
rather than documenting that it is not working)
The previous approach was directly prevented Qt from changing
single step (on e.g resize) at all. This patch only prevents Qt from
changing when a user explicitly has called the function
QScrollBar::setSingleStep (in pixel scroll mode).
That is we expect that calls to setSingleStep means that the user actually
wants to set the singleStep and doesn't want Qt to control that value.
Furthermore it is possible to switch back to the automatically adjusted
singlestep with QScrollBar::setSingleStep(-1).
[ChangeLog][QtWidgets][QAbstractItemView] QTBUG-7232 - In ItemViews
when scrollMode is set to scrollPerPixel, it is now possible to
change the single step. Qt will automatically adjust the single step
until setSingleStep is called. When setSingleStep is called it will
however respect the set and stop doing automatic changes of the value.
Calling setSingleStep(-1) will switch mode back to automatic adjust.
