4d407dc666 pictures: turn QString into std::string for filenames
For undo of picture manipulation, it will be crucial that the
model and the core have the same order of pictures. The first
sort criterion will be time, the second filename in the case
that two pictures have, for whatever reason, the same timestamp.

However in the core we us C-strings and thus sort byte-wise
using strcmp. In the Qt-part we use QStrings, which sort according
to unicode encoding. To enable consistent sorting, change the
Qt-part to std::string, which uses a C-style 0-terminated string
as its backing store.

One might argue that in general filenames should use system-encoding
and therefore use std::string instead of QString. However, a
broader conversion to std::string turned out to be very painful,
since Qt is (deliberately?) difficult to use with std::string.
Notable all the file-manipulation functions don't take std::string
by default. Thus, this commit only converts the internal data
of DivePictureModel, but continues to use QString for the Qt-facing
interface.

30133946e0 models: emit dive changed signal when cylinders edited
To display changed SAC values it is necessary that the models
emit changed signals when cylinders are edited. An alternative
might be that the undo commands emit dive-changed signals themselves.

Fixes #2814.

0ccc0f04bb dive sites: properly reload dive site model on desktop
In 9310d72943, resetting of the dive
sites was moved to DiveTripModelBase::reset(). This seemed like a
good idea, because it means that the location list is reloaded
every time the dive list is reset.

Unfortunately that function is only used on mobile, thus on desktop
the dive site model is not updated. Do that in
MultiFilterSortModel::resetModel(), because this is always called
when the dive list is reset. Desktop differs from mobile in that
two different models are used depending on whether we are in list
or in tree mode.

8b93d67106 mobile: remove fine-grained notification
When initializing the fulltext-cache and the dive-list, every
100 dives a notification was shown. I had a feeling that this
made startup significantly slower, but that could have been
purely psychological.

Therefore I measured and indeed, removing the fine-grained
notification, it becomes *significantly* faster. For a 3500
dives test log with mobile-on-desktop:

Initialization of the fulltext: 1350 ms -> 730 ms (-46%)
Initialization of the divelistmodel: 689 ms -> 113 ms (-83%)

Let's remove the fine-grained notification. There *is* a visual
indication of work-in-progress anyway.

24a7dbde16 CylindersModel: use flag to decide whether we are in planner
On desktop, we have two CylindersModel concurrently: One in the
planner and one on the equipment-tab. They act differently, because
the former modifies displayed_dive directly, the latter issues
undo commands.

To differentiate, we used the in_planner() function. However, that
appears extremely brittle, especially when combined with undo-commands.
Therefore when generating the model, pass in a parameter that says
whether this is for the planner or the equipment tab and use
that flag to decide how to act.

01fa983182 undo/cylinder: call undo command to edit cylinder fields
Call an undo command when editing cylinders, but only if on
the EquipmentTab.

To keep code changes small, make a copy of the cylinder first,
then edit the cylinder as before and then either call an undo
command (EquipmentTab) or overwrite the old cylinder (Planner).

The memory management here is a bit strange: Since the undo-command
itself makes a deep-copy of the passed in cylinder, we only do
a shallow copy. If we have to change the type, we allocate the
string with an std::string, so that the memory is automatically
freed at the end of the function. However, this means that in
the planner we have to make a deep copy first, swap old and
new cylinder and finally release the old cylinder. Certainly
not ideal, but for now the pragmatic thing to do.

1dcc885bb2 undo/cylinders: Implement editing of the type
This one is tricky, as when browsing through the types-combobox,
the user is presented with presets without actually changing the
dive. We do not want an undo-command for every change-event in
the combo-box.

Therefore, implement a scheme analoguous to the weight-editing:
A temporary row can be set / committed or reset. Sadly, the
code is more complex because we have to consider the planner,
which is not included in the undo system.

Firstly, the planner uses a different model, therefore all
interactions are channeled through setData() with special roles.
Secondly, in the planner we shouldn't place an undo command,
but simply overwrite the dive.

It is unclear when we can initialize fonts. Try to move initialization

of that class. For consistency, also make the invalidBrush a member
of this class.

This now means that the diveData function cannot be static anymore,

9310d72943 models: update divesite-model when clearing/updating dive model
When the dive list is cleared or updated, the entries in the
divesite-model become stale and therefore the divesite-model
(with the actual name LocationInformationModel) also must be
updated. This was done manually in some parts of the code and
forgotten in others. Therefore, do it directly in the clear()
and reset() function of the dive list-model.

This might be a bit of a layering violation: why should one
model call into another if they are not in parent/child
relationship? However, this seems easier than introducing
a global "reset dives" function that coordinates the models.

Moreover, it does not appear 100% safe: if the clearing of
the divesite model causes accesses to the divelist-model,
they happen in the midst of a model reset and we had horrible
bugs with that kind of things. However, I don't think that
should happen.

c34b7857fc mobile/divelist: implement model that shows all dives in trip-order
MobileSwipeModel is probably not an ideal name, but all I could come up with.

One of the main complications here is that our list is reversed with respect to
the source model. We should change that one day.  Probably by moving the
sorting down to the core-model.

Since looking up the source row is somewhat expensive, the lookup is cached for
a single entry because accesses come in bursts for a single dive. This should
be a good compromise and avoids keeping track of a full row-to-dive array.

cb80ff746b crash fix: Don't cast to CylindersModel or CylindersModelFiltered
The tank-info-delegate cast its model to CylindersModelFiltered,
since this is what the equipment-tab uses since implementing the
filtering of unused cylinders. However, the planner users the same
delegate and still uses the unfiltered CylindersModel. This means
that the (dynamic) cast returns a null pointer and crashes.

One possibility would be to derive CylindersModelFiltered and
CylindersModel from the same class that defines virtual functions
and cast to that class.

This is a different attempt: don't cast (i.e. stay with a
QAbstractItemModel and play it via Qt's model-view system. Firstly,
replace the passInData function by a role to setData(). Secondly,
read the working-pressure and size via new columns using data().

ee553e059d Filter: move actual filtering loop to core/divefilter.cpp
The DiveFilter class defined the showDive() function to test
whether a dive should be filtered or not. This was used in
DiveTripModel to loop over all dives or all dives affected by
an editing action.

This restricts us in how we do filtering: We can't use indexes
that give us directly the result. To make the filtering more
flexible, move the actual loops that do the filtering to
the DiveFilter class.

The undo-commands likewise called directly the showDive()
function to check whether newly added dives are shown.
Use the new interface here as well.

a45c5faa8c Filter: update current dive if change hides current dive

hidden, a new dive is made current. However, when a dive is
hidden because it was edited, it is still shown.

Make this consistent by also selecing a new current dive
in the latter case. Do this by comparing the current_dive
before and after calculating the filter. Since this is now
done in multiple places move this code to the ShownChange

7633d5feec Dive list: filter dives at DiveTripModel level
We use a QFilterProxyModel to filter out dives that are hidden
according to the current filter-criterion. Instead, filter the
dives already at the DiveTripModel level. Filter out hidden
dives immediately when receiving them. The only difficult case
is when dives are changed, because then visibility can change.
This means that we have three cases to consider:
  1) Visibility unchanged -> send change signal
  2) Change from hidden to unhidden -> add dives to model
  3) Change from unhidden to hidden -> remove dives from model
Things get complicated by the fact that the tree-version of
the model might have to add/remove full trips!

In the planner we used to filter out "unused" cylinders as in the

6622f42aab Cylinders: Add CylindersModelFiltered
When the show_unused_cylinders flag is not set, the cylinder tables
in the equipment tab and the planner should not show unused cylinders.
However, the code in CylindersModel is fundamentally broken if the
unused cylinders are not at the end of the list: The correct number
of cylinders is shown, but not the correct cylinders.

Therefore, add a higher-level CylindersModelFiltered model on top
of CylindersModel that does the actual filtering. Some calls are
routed through to the base model (notably those that take indexes,
as these have to be mapped), for some calls the caller has to get
access to the source model first. We might want to adjust this.

For filtering, reuse the already existing show_cylinder function
and export it via CylindersModel.

1a85b0e941 mobile/summary: create DiveSummaryModel
Instead of passing the dive summary via a completely unstructured
QStringList to QML, implement a dynamic model. For potential reuse
on desktop (though somewhat unlikely) the model has two interfaces,
one for QtWidgets and one for QML. The former is based on columns,
whereas the later is based on roles. The number of columns is
set dynamically. The roles currently support access to two columns.
If more columns should be accessed from QML, more roles have to
be added manually.

This commit only creates the model and hooks it into QMLs global
context, but does not yet change the QML page.

3fc2da567b Dive site: ignore dive sites without location in proximity search
When editing a dive site, the user can search for close dive sites
to merge duplicates. Dive sites without location are treated as
being located at 0N0E. This makes no sense, because:

When selecting a dive site without location, we shouldn't list
dive sites close to 0N0E.

Likewise when having a dive site close to 0N0E, we shouldn't list
dive sites that have no location.

Therefore, ignore these cases.

This also means that now dive sites without location are not

might be a debatable point.
