struct device is a core data structure and therefore shouldn't use QString.
QString stores as UTF-16 (which is a very questionable choice in itself).
However, the real problem is that this puts us in lifetime-management
hell when interfacing with C code: The UTF-16 has to be converted to
UTF-8, but when returning such a string, this puts burden on the caller
who has to free it. In fact, instead of looping over devices from C-code
we had a callback that sent down temporary C-strings with qPrintable.
In contrast, std::string is guaranteed to store its data as
contiguous null-terminated and C-compatible strings. Therefore,
replace the QString by std::string. Keep the QString just in
one place that formats a hexadecimal number to avoid any
potential change.
The disadvantage of using std::string is that it will crash
when constructed with a NULL argument, consistent with C-style
functions such as strcmp, etc. Arguably, NULL is different
from the empty string even though we treat both as the same.

We keep track of device, i.e. distinct dive computers with id in the core.
The corresponding code stuck out like a sore thumb. Firstly, because it
is C++. But more importantly, because it used inconsistent nameing conventions.
Notably it defined a "DiveComputerNode" when this is something very different
from "struct dive_computer", the latter being the dive-computer related
data of a single dive.
Since the whole thing is defined in "device.h" and the function to create
such an entry is called "create_device_node", call the structure "device".
Use snake_case for consistency with the other core structures.
Moreover, call the collection of devices "device_table" in analogy
with "dive_table", etc.
Overall, this should make the core code more consistent style-wise.

When moving dives between trips, the core moves the dives internally
and sends a signal to the model. The model adds and removes the dives
accordingly. However, when adding the new dive, the old trip hasn't
changed its position, so the ordering is wrong leading to an inconsistent
state.
Therefore, remove the dives first and then readd them. There could
still be pathological cases where this fails. However, in the short
term this is an improvement. Note that in similar cases, the dives were
indeed removed then added, so this case here seems to be an oversight.

In a previous commit, auto-filling of weight based on type was
changed to be only performed if the user hadn't already set a
weight, by testing for weight=0.
However, when the user edited the type and tabbed back and forth,
that counted as an edit and therefore the weight would not
change anymore.
To refine this, introduce an "auto_filled" flag to the weightsystem,
which is set if the weight is automatically filled and cleared if
the weight is edited. Update the weight if it was zero *or* auto-filled.
The flag is not saved to disk, but that should be acceptable. If the
user saves and reloads, we can assume that they meant the weight
to be set to the default value.

When importing from other software, it happens that weights are imported
without their type. When the user changes the type, the imported weight
is overwritten, which is not exactly a friendly behavior.
On the other hand, when changing the type after creation of a weight
entry, it is preferrable to set a default weight. This is convenient
for people who commonly use the same weight.
As a compromise, set the default weight only if it was unset. We
recognize this by a weight value of 0 g.

To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.
Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.

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.

MobileSwipeModel is probably not an ideal name, but all I could come up with.

Since looking up the source row is somewhat expensive, the lookup is cached for

2) Change from hidden to unhidden -> add dives to model
3) Change from unhidden to hidden -> remove dives from model

When the show_unused_cylinders flag is not set, the cylinder tables

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

DiveTripModelTree::topLevelChanged() has pretty complex code, as
it has to handle the fact that when adding/removing a dive from
a trip, the trip can change its position.
The code did not account for the fact that when moving an object
back in the top level list, one has to subtract one from the new
index, because the object was removed somewhere in the front of
the list.
To make matters worse, when an entry stayed where it was, this
was realized by moving the entry right behind itself, which of
course means that it stays where it is. But this meant that in
the by far most common case (no moving) the wrong entry was
updated.

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit

Some widgets copy the full plot info. Free these data on exit to
prevent monstrous valgrind reports.

All accesses to the pressure data were converted to use functions.
Therefore it is now rather trivial to dynamically allocate the
pressure array and just change the functions.
The only thing to take care of is the idiosyncratic memory
management. Make sure to free and copy the buffer in the
appropriate places.

The model was accessing the pressure data directly. Instead,
use the accessor functions so that the core structure can
be changed more easily.

When keeping track of cylinder related data, the code was using
static arrays of MAX_CYLINDERS length. If we want to use dynamically
sized cylinder arrays, these have to be dynamically allocated.
In C++ code, this is trivial: simply replace the C-style arrays
by std::vector<>. Don't use QVector, as no reference counting or
COW semantics are needed here. These are purely local and unshared
arrays.

get_gas_used() returns the volume of used gases. Currently,
an array with MAX_CYLINDERS is passed in. If we want to make the
number of cylinders dynamic, the function must use an arbitrarilly
sized array.
Therefore, return a dynamically allocated array and free it
in the caller.

This is even harder because setActiveTrip is called from an action slot from
QML. If the C++ code called from that slot causes the object to which this slot
belongs to be destroyed, we get very strange crashes. The only workaround I
could come up with was to update the filter asynchronously.
This all seems very ugly and fragile.
