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.

After invalidating the filter, the dive-selection was modified to
ensure that at least one dive is selected. This was done in the
filter code, but it seems preferrable to do this in the dive-list
code, which has direct access to the selection-model.
Therefore, move the code from MultiFilterSortModel to DiveListView.
While doing so, split the code in DiveListView into more functions to:
1) Get the index of the first dive (if any).
2) Select the first dive (if any).
This allows a distinct size reduction of conditional compilation
in MultiFilterSortModel (accesses to MainWindow are not possible
in mobile code).

The keeps track of different sub widgets needed by other parts
of the code, notably:
MainTab
PlannerDetails
PlannerSettingsWidget
ProfileWidget2
DivePlannerWidget
DiveListView
Access to these widgets was provided with accessor functions.
Now these functions were very weird: instead of simply returning
pointers that were stored in the class, they accessed a data
structure which describes the different application states.
But this data structure was "duck-typed", so there was an
implicit agreement at which position the pointers to the
widgets were put inside. The widgets were then down-cast by
the accessor functions. This might make sense if the individual
widgets could for some reason be replaced by other widgets
[dynamic plugins?], but even then it would be strange, as one
would expect to get a pointer to some base class.
Therefore, directly store the properly typed pointers to the
widgets and simply remove the accessor functions. Why bother?

Currently, the filter is recalculated if a filter-entry is changed.
This also happens if the counts of a filter-entry changes. This

Instead of reloading all the filter, only increment / decrement the
count of the entries of added / removed dives.
Originally, this was planned to be done via the signals from the

if the filter decides that the new item is selected, this has to
be done *before* adding the dive. Otherwise, it wouldn't be shown.

Since FilterModelBase now contains complex data (counts and checked),

The filter code was an unholy intermixture of backend and frontend
logic, which made it hard to access it from outside of the UI.
Notably, it expected that Qt would call filterAcceptsRow on all rows.
For trip-view, apparently the filter functions were called twice
(once for filtering the trip, then for filtering the individual dives).
Make the filtering explicit, by calling showDive() for all dives in
MultiFilterSortModel::myInvalidate(), setting the hidden_by_filter
flags accordingly and ultimately invalidating the filter.
The UI code only accesses the hidden_by_filter flag set previously.
The "justCleared" flag can then be removed, since accessing the filter
does not have side effects. Moreover, there is no noticeable performance
gain by returning out early.

The function DiveListView::fixMessyQtModelBehaviour() was used to
expand the first columns of dive-trips in the dive-list view.
This function was called everytime that the dive-list was modified.
It is kind of ludicrous that external callers would have to
tell the DiveListView, when it has to update its column headers.
Instead, place this functionality in the overriden reset() and
rowsInserted() functions, as these are the only ways that
rows can be added. Change the DiveTripModel to use the proper
beginResetModel()/endResetModel() pair instead of the previous
full deletion and full repopulation using the beginRemoveRows()/

This "bug" is found using Qt 5.10 compiled in developer mode. Access
the filers, click a little around here, close the filters. Almost every
time the following assert is triggered:
ASSERT failure in QPersistentModelIndex::~QPersistentModelIndex:
"persistent model indexes corrupted", file itemmodels/qabstractitemmodel.cpp, line 643
This is relatively deep down in Qt, and it is triggered by clearing the
filters. Trying to force a crash when using the same scenario in Qt 5.10
compiled for production (so no active asserts) did not result in a crash.
So, upto this time, it is unclear if the Qt assert points out a real problem,
or it is some false alarm (for whatever reason).
Further investigation shows that the assert can be solved by changing the
invalidate() to an invalidateFilter(). Indeed, the last variant is a little
more lightweigt, and does seem to do the same job from a functional point
of view (in this case).

The *FilterModels had a number of of virtual functions, which only
accessed members of the base class. Moreover, these functions were
identical and generated with macros. Therefore, move these functions
to the base class.
The one excption is data(), which uses different count functions
(passed as a macro parameter). Thus, introduce a virtual countDives()
function and likewise move data() to the base class. A function pointer
might be even more clear, but since the rest of the code/Qt relies
heavily on runtime polymorphism, let's do the same here.
The only macros left are those creating the singleton accessors.

If the user implicitly adds a dive site by editing a dive, and

Since commit 01d961086c, the location filter
list is updated if a dive site is edited. The problem is that if the
name of a selected dive site is changed, the selection is lost.
Therefore, before repopulating, inform the location filter that a dive
site changed its name. The location filter then internally changes the
name and can properly transfer the old selection on repopulate. This is
performed via the new LocationInformationWidget::nameChanged signal,
which is connected to the new LocationFilterModel::changeName slot.
A special case to be handled is the following:
[ ] Site 1
[x] Site 2
and "Site 2" being renamed to "Site 1", i.e. both sites being merged.
Here, the merging is detected and "Site 1" will likewise be checked:
[x] Site 1
[x] Site 1
No merging is performed, as the list will be repopulated anyway.

This replaces a dynamically allocated array of bool by std::vector<char>.
1) This makes the code shorter and less error prone, because memory

2) It fixes a bug in the old code:
memset(checkState, false, list.count()) is wrong, because bool is
not guaranteed to be the same size as char!
Two notes:
1) QMap<>, QVector<>, etc. are used numerous times in the code, so
this doesn't introduce a new C++ concept. Here, the std:: version
is used, because there is no need for reference counting, COW
