The UI talks to the filter model. Therefore route clearing of
data through that model instead of accessing the source model
directly.
This will allow us to remove the DiveTripModel::instance()
function and makes control flow less "jumpy".

The DiveListView caught signals from the DiveTripModel
with the corresponding indexes. However, the DiveListView
is actually connected to the MultiFilterSortModel and
thus has to translate the indexes.
Instead, catch the signals in the MultiFilterSortModel,
transform them and resend. Let the DiveListView get
its signal from the MultiFilterSortModel.
Yes, this makes things less efficient because there is
an extra signal. On the upside, the makes data-flow much
more logical. Selection will have to be fixed anyway.

Split out the actual filtering from the MultiFilterSortModel.
Create a DiveFilter class that does the actual filtering.
Currently, mobile and desktop have their own version of this

The idea here is that the trip-model and undo-commands have
direct access to the filter-function and thus can take care
of keeping track of the number of shown dives, etc.

We have a very fundamental problem with data-duplication in
core and qt-models. In a particular case, this led to an easily
reproducible crash:
1) An undo command moved the last dive of a trip to another.
2) When an undo-command removed the last dive of
a trip to a different trip, the dive was removed from the
trip in the core. Then, the model was updated.
3) That lead at first to a rearrangement of the trips, because
the trip with the added dive is moved before the trip with
the removed dive.
4) In such a case, the filter-model checks the visibility of
the trip.
5) Since the trip with the removed dive has no dives in the core,
visibility was determined as false.
6) From this point on the mappings of the QSortFilterProxyModel
were messed up. Accesses led to crashes. It is unclear
whether this is a Qt bug or only a QOI issue.
As a quick-fix, cache the visibility flag of trips directly
in the Qt-models. Don't set the visibility directly in the
core, but go via the Qt-models. Thus, a more clear layering
is achieved.
In the long run, we can hopefully get rid of the data-duplication
in the models.

Invalidating the filter can cause numerous selection-change notifications.
These cause a full UI reload. Therefore, go into "command" mode that was

When switching between the dive-site-table to the dive-site-edit
tabs, the filter would be set to a dive site. Usually, this would
be the same dive site as before. Nevertheless, this caused a full
map-reload. Detect if the dive-sites to be filtered are the same
and turn this operation into a no-op.

The dive-site-edit and dive-site-table tabs both put the filter
into a special dive-site mode. When switching between both, it
could happen that the one got its show befor the other got
its hide event.
Thus, the first would start dive-site filtering and the second
stop it. Now the app was not in filter mode even though it should.
To solve this problem, add reference counting for the filter's
dive-site mode. In both tabs call the enter/exit functions
on show/hide. In the dive-site-table tab, when the selection
changes, use a set function that doesn't modify the reference count.

In the edit-dive-site tab the filter is switched to a particular

The filter code is strange: it actually only checks the

Quite useful if one dives using more than one dive mode. For the

The DiveTripModel was used to represent both, trip and list views.
Thus many functions had conditionals checking for the current mode
and both modes had to be represented by the same data structure.
Instead, split the model in two and derive them from a base class,
which implements common functions and defines an interface.
The model can be switched by a call to resetModel(), which invalidates
any pointer obtained by instance(). This is quite surprising
behavior. To handle it, straighten out the control flow:
DiveListView --> MultiFilterSortModel --> DiveTripModelBase
Before, DiveListView accessed DiveTripModelBase directly.
A goal of this commit is to enable usage of the same model by mobile

The dive list was sorted using the default-sorter of
QSortFilterProxy model. This is mighty inflexible as it
considers only one column. This has the funky effect that
for rows with identical elements, the sort order depends
on the previous sorting.
Implement a lessThan() function in the MultiFilterSortModel,
which simply hands the sorting down to the actual model.
This might be considered a layering violation, but it makes
things so much easier.
Sadly, it seems like the column-to-be-sorted is transported
in the provided indices. Therefore, the comparison is chosen
using a switch for *every* comparison. It would seem much
more logical to set a function pointer once and use that.
Further investigations are necessary.

The data-flow from C-core to list-view is as follows:
C-core --> DiveTripModel --> MultiSortFilterModel --> DiveListView
The control-flow, on the other hand, differs as DiveListView
accesses both MultiSortFilterModel and DiveTripModel, whereas
MultiSortFilterModel is mostly unaware of its source model.
This is in principle legitimate, as the MultiSortFilterModel might
be used for different sources. In our particular case, this is
not so. MultiSortFilterModel is written for a particular use case.
Therefore, model control-flow follow after data-flow: Let MultiSortFilterModel
set its own source model and DiveListView access the MultiSortFilterModel,
which then manages its source model.
This is not bike-shedding, but will enable a more flexible and
higher-performance sorting.

To test whether to show a dive, the UUIDs of the filtered-by
location and the dive-site of a dive were compared. Since UUIDs
are unique (as the name implies), directly compare pointers.
Note: this code comes from a time when the filtered-by location
was not a pointer, but a copy.
Moreover, the if tested first for the same name, then (logical-or)
for the same uuid. This makes no sense, as the same dive-site
implies the same name. This code likewise can be explained by
historic reasons: the filtered-by location may have contained
a different name. Swap the order of the conditions: first test
for the same object and only of the objects differ, test for
the same same.
