We keep it private to QmlProfilerModelManager and proxy the last few
methods that were directly called on the model. This enables us to
remove the QmlProfilerDataModel class by integrating what is left of it
into QmlProfilerModelManagerPrivate in a next step.

foreach() is slow in hot loops like these. Also, by moving frequently
used children to the front we reduce the effort to find them in
further iterations.

The QML compiler can run asynchronously and produce ranges that don't
match up with other QML/JS ranges. The flame graph model assumes that
all ranges are perfectly nested, and produces incorrect data if they
aren't. The compile ranges are perfectly nested among themselves, and
the other QML/JS ranges are also perfectly nested among themselves, so
we can fix this by keeping separate stacks for them.

Methods with default parameter in the base class should also have a
default parameter in the derived class. As rowCount() is Q_INVOKABLE
columnCount() should also be.

We want to get rid of the big master list of QmlEvent in
QmlProfilerDataModel, as that gets very large for longer traces. In
order to reduce the dependencies on that list we load the events on the
fly into the child models while they are being received, rather than
having the child models query QmlProfilerDataModel for the event list
later.
As the trace client so far only emitted rangedEvent() for complete
ranges we run into problems with models that need their events sorted.
The rangedEvent() signals were sorted by end time, rather than start
time which makes it inconvenient to analyze them in a stack based way,
for aggregation. This is solved by passing on all the details from the
trace client to the models, with the QmlProfilerDataModel aggregating
the type information before having the events dispatched to the child
models.

The progress bar in the state widget was rather meaningless. We rarely
know how many events we expect and it's rather hard to tell how long
each model will take to process them. Instead, we just show a 0-ranged
progress bar to tell the user that "something is happening".
