String comparison drew on a large number of internal functions such as
qMemEquals, ucstr{n,}{i,}cmp, and QString::compare_helper, all with
wildly different calling conventions. E.g. ucstrncmp took its
arguments as QChar*, while ucstricmp required ushort*. A complete
cleanup of these functions is left for another patch. This patch, as a
first step, centralizes calls to these functions.
Introduce two helpers, qt_compare_strings(QStringView, QStringView, cs)
and qt_compare_strings(QStringView, QLatin1String, cs) and replace all
uses of said lower-level functions with calls to these two functions.
I'm using QStringView instead of the more traditional (QChar*,int)
pairs, since we get two major benefits:
1. The onus of checking for valid arguments is put on the callers
(creating QStringViews with negative sizes is UB), allowing these
functions to be noexcept, even though the implementation still
calls functions taking (ptr, size) or (ptr, ptr) tuples. Duly add a
few asserts where we construct QStringViews from (ptr, size) pairs
passed in through exported API.
2. Since QStringView can be constructed from both ushort* and QChar*,
we no longer have to cast at the call sites. Much of the
simplification of the code is due to reduced casts.
The Windows 64-bit ABI stipulates that no values greater than the
register width can be passed in registers (no register pairing as with
all other ABIs), but a) that is their problem, b) it does not seem to
matter within a TU, c) MS is known to introduce new calling
conventions all the time (like __vectorcall in MSVC2013), so maybe
they will introduce a __faststructcall at some point and d) giving up
on the above-mentioned two benefits for an unknown runtime cost means
we're falling prey to premature optimization.
As a consequence of the cleanup, qMemEquals() and ucstrnicmp(ushort*,
ushort*, int) can already be removed.
Port the ucstr{i,}cmp() functions to QChar/char to avoid casting in
their only callers, qt_compare_strings().
Port ucstrcmp from int to size_t indices to avoid MSVC warnings when
passing QStringView::size() to them.

Consider this pseudo code:
setSystemClip(region);
setSystemTransform( scale 2x );
setSystemTransform( scale 2x );
The second call to setSystemTransform should be a noop. Yet, with
the current code in setSystemTransform, the region would be scaled
twice by 2x and thus the clipping would be incorrect.
Fix that by saving the original untransformed clip and in
setSystemTransform recalculate the effective transform.
This is also a better fix for QTBUG-44067 /

QStringView is a simple container for (const QChar*, int) and (const
char16_t*, size_t). It acts as a replacement interface type for const
QString and const QStringRef, and enables passing all kinds of
string-like types to functions otherwise expecting const QString& -
without the need to convert to QString first.
The use of this new class is guarded by a macro that enables three
levels of QStringView support:
1. offer QStringView, overload some functions taking QString with
QStringView
2. like 1, but remove all overloads of functions taking QStringRef,
leaving only the function taking QStringView. Do this only where
QStringRef overloads tradionally existed.
3. like 2, but replace functions taking QString, too.
This is done in order to measure the impact of QStringView on code
size and execution speed, and to help guide the decision of which
level to choose for Qt 6.
This first patch adds QStringView with most of its planned
constructors, but not much more than iterators and isNull()/isEmpty().
Further patches will add support for QStringView to QStringBuilder,
add QStringView overloads of functions taking QString, and add the
complete API of const QString to QStringView.
[ChangeLog][QtCore][QStringView] New class, superseding const QString
and QStringRef as function parameters, accepting a wide variety of

QDockAreaLayoutInfo::reparentWidgets does not reparent floating
widget (because of the item.skip test)

3. Tab "Foo" together with the black dock widget
4. Drag "Foo" out. (Now, Foo is still a child of the QMainWindow,

5. Drag the black dockwidget out. (This, in fact, crates a
QDockWidgetGroupWindow which contains the black dockwidget and the
floating "Foo", but since "Foo" is floating, it is not reparented)
6. Destroy "Foo" using the "Dock Widgets" menu. (Since Foo's parent
is the QMainWindow, it is not removed from the QDockWidgetGroupWindow's
layout, which will cause crash on the next relayout)"
