The only place where we used them was handlesTypeId(), and there it was
wrong. Each QmlProfilerTimelineModel has exactly one main feature it
subscribes to. It might additionally accept events of some auxiliary
features for context, but it doesn't really "handle" the respective
types in the sense that you could, for example, attach notes to them.
Therefore, just checking for the main feature is the right thing to do.

The way the notes model works requires every timeline model to have a
different ID. Conversely no other kind of model actually needs an ID.
Therefore it makes sense to have the TimelineModelAggregator manage the
IDs as every timeline model will sooner or later be associated with an
aggregator.

We always want either the total number of event types or one specific
type. There is no need to expose the fact that we keep them as a vector.
Also, use int as the type of the "number" methods as that aligns better
with Qt containers, and rename the methods. We don't need to state the
fact that we've loaded the events and types at some point.

The scale parameters are converted to single precision float anyway as

methods to be single precision, too.
The min/max row values should really be 64bit as 32bit values are not

It makes no sense to return a QColor as the only things we are using
are the red, green, and blue components. Furthermore, colorFromHue()
can only generate 360 different colors which we can easily cache
instead of recalculating them on each request.
This significantly reduces the time it takes to update the timeline
render nodes.

We want the editor to jump to the right source location when selecting
different events from the timeline. If all memory events have the same
ID this doesn't work. Now they of course have the IDs of the origin
events, but that's not a problem because when you select first the
memory event and then its origin, the editor position does in fact not
have to change.
As an added benefit, the typeId cannot be -1 anymore now.

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.

All the models do the same thing when loading the data: They iterate
the list of events, determine for each one if they accept it, and if
so, they load it. After the list has been fully loaded, they do some
finalization. This can be centralized, and ultimately we won't need to
expose the central QVector<QmlEvent> for that anymore.

The progress bar in the state widget was rather meaningless. We rarely

The QmlTypedEvent is mainly useful to read a generic QmlEvent and
QmlEventType from a QPacket. QmlEventType has a stream operator to do
exactly that. QmlEvent also gets further options to store 32-bit data
in addition to 64- and 8-bit data. Also, with the more generic storage
layout we can reduce the memory consumption of range events by 50%.
This comes at the cost of additional memory allocations for non-range
events, but as non-range events are significantly less frequent than
range events, this is a good tradeoff. Finally the new storage layout
lends itself to efficient serialization, which will help when
developing new storage and transfer formats for QML traces.
