The code is rather complex. Firstly, we have different representations
of pictures throughout the code. Secondly, this tries to do add the
pictures in batches to the divepicture model and that is always rather
tricky.

QVector doesn't have a function to insert a range of pictures,
which we will need for undo of image adding/deletion.
Moreover, std::vector gives us stronger guarantees. For example,
if capacity is large enough, it guarantees that there will be
no reallocation and thus iterators stay valid. I have not found
such a guarantee in the Qt docs.

For consistency with equipment, use our table macros for pictures.
Generally tables (arrays) are preferred over linked lists, because
they allow random access.
This is mostly copy & paste of the equipment code.
Sadly, our table macros are quite messy and need some revamping.
Therefore, the resulting code is likewise somewhat messy.

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.

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.

This will be temporarilly used by the planner to mark consumption of
air at the surface. Do this by creating a new function add_cylinder,

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.

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.

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.

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.

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.

To mark invalid dives, we use a struck-out font, which was a static

It is unclear when we can initialize fonts. Try to move initialization
to the constructore of DiveTripModelBase and make the font a member
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,

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.
