When blocks are added or removed in block groups, i.e. items added or
removed from text lists, the whole group is marked as changed, but the
calculation of the before/after group length would be one off. That
was reflected in the contentsChange signal.
Add unit test. Since the whole group changes when list items are
added, text is removed and the change-begin is not where the cursor
was when the change was made.

376e3bd8ec added the new class for Qt 6.1,
but during header review we concluded that using a class introduces
complexity wrt instance ownership and API design that can be avoided by
using a std::function instead.
The functionality is tied to QTextDocument, so the type definition and
the default provider API is added there.
Since std::function is not trivially copyable, the atomicity of the
previous implementation is not maintained, and concurrent modifications
of and access to the global default provider from multiple threads is
not allowed. The relevant use case can be supported by implementing a
resource provider that is thread safe.

QTextDocument and the text editor classes suggest to override
their loadResource() methods to provide data associated with
a text document. This approach has the following drawbacks:
- it requires subclassing
- there is no way to set a global resource provider
- QLabel is missing virtual loadResource() method and
it can't be added without breaking ABI
QUrlResourceProvider is designed to solve these issues.
One should create a derived class that implements
QUrlResourceProvider::resource(). The objects of the derived
class then can be set for any text document.
The default resource provider can be set with
QUrlResourceProvider::setDefaultProvider().
This change also adds QLabel::setResourceProvider(),
which doesn't break ABI.
[ChangeLog][QtGui][Text] Introduced QUrlResourceProvider that allows to
load resources for HTML. It is intended to replace the use of

things to take care of are

The cursors in QTextDocumentPrivate are held in a QList.
This becomes a serious performance problem with lots of
extra selections due to a call to
QTextDocumentPrivate::removeCursor() from the QTextCursor
destructor.
Given the following test program:
QPlainTextEdit *editor = ...
std::list< QTextCursor> list;
for(int i = 0; i < 100000; ++i) {
QTextCursor c(editor->document());
c.setPosition(std::rand()%100);
list.push_front(c);
}
list.clear(); // <-- clear calls hangs for 3+ seconds
// due to time spent in
// QTextDocumentPrivate::removeCursor()
// due to QList::removeAll() call
Note the push_front because it exacerbates the issue because
the entire list will be traversed.
The change submitted changes the structure to a set,
removing the issue.
In theory, this limits that a cursors cannot be in the
structure twice, but this neither happens nor would it make sense.

When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

In Qt, we have QTextOption::tabStop, QTextEdit::tabStopWidth and
QPlainTextEdit::tabStopWidth.
Neither are very good names, since the tab stop is neither a
numerical value as in the former, nor does it have any dimensions
that can be measured, as in the latter. Vertical text advances
may also be supported by Qt at some point in the future, at
which point the name would make even less sense.
At the same time, we expose the actual type of the tab stop
distance as floating point in the QTextEdit and QPlainTextEdit
API instead of always rounding it to an int.
To avoid duplicating either of these APIs in Qt Quick, we
introduce tabStopDistance as the common term instead and deprecate
the old names.

With the side-effect that variables and functions in the argument are
now "used". This means we don't need to #ifndef functions only used in
assertions: the compiler will eliminate them by dead code elimination.
Due to the mandatory short-circuiting of the condition, no functions
will ever be called and this expands to no more code than before.
On the negative side, because we won't get warnings for unused variables
initialized outside the Q_ASSERT, non-inlineable calls will not be
elminated by dead code elimination, so they will remain in release code
without warnings.
Because of the expanded code now in Q_ASSERT, the Intel compiler's
optimizer gets thrown: it complains that the non-void function is
failing to return anything, so I had to add two return statements.
