Qt's memory management scheme is completely broken and messes
with common expectations.
QObjects are organized as a tree. The children are destroyed
in the destructor of QObject. This means that they are destructed
after the destructor of the parent object has run and its
sub-object were destructed. Obviously, this makes no sense as
the child objects should be able to access their parent at
any time.
To restore the commonly expected deterministic order of
construction and destruction, one might simply do away with
Qt's silly object tree and organise things using classical
subobjects. However, that breaks with the Qt-generated UI
classes: The objects generated by these classes are *not*
destructed with the UI class. Instead, they are attached
to the widget's QObject tree. Thus these are again destructed
*after* the widget! Who comes up with such a scheme?
In our case this means that we cannot have models used for
TableViews as subobjects, because the TableView needs the
model to save the column widths in the destructor. Which,
as detailed above is called *after* the desctructor of the
widget! Thus, turn these models into heap-allocated objects
and add them to the QObject tree.
Funilly, this exposes another insanity of Qt's QObject tree:
Children are destructed in order of construction! One would
expect that if objects are constructed in the sequence
A, B, C one can expect that C can, at any time, access B and A.
Not so in Qt: The destruction order is likewise A, B, C!
Thus, take care to init the widgets before the model. Jeez.
Finally, print a warning in the column-saving code of
TableWidget, so that these kind of subtleties are caught
in the future.

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.
Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

When connecting a model to the TableModel class, it would connect
clicking on an item to the remove() slot of the model.
This breaks the program flow implied by the undo code:
Ui --> Undo-Command --> Model --> UI
Moreover, the naming of the remove() slot is illogical, because
clicks can also have different effects, as for example in the
cylinder-table.
Therefore, move the connect() call from TableModel to the
callers. In the case of TabDiveSite, move the remove() function
from the model to the TabWidget, where it makes more sense.

This one is a bit more tricky. There are two modes: set dive site
and set newly created dive site. This is realized using an OO model
with derived classed. Quite convoluted - but it seems to work.
Moreover, editing a dive site is not simply setting a value,
but the list of dives in a dive site has to be kept up to date.
Finally, we have to inform the dive site list of the changed
number of dives. Therefore add a new signal diveSiteDivesChanged.
To send only one signal per dive site, hook into the undo() and
redo() functions and call the functions of the base class there.

Create a new undo-command for deleting dive sites. If there are dives

The LocationInformationModel used to sort its entries and was completely
rebuilt after every change. This makes it rather complex to support
incremental changes.
Instead, keep LocationInformationModel sorted by UUID so that indexes
are consistent with indices in the core dive site table.
Implement sorting by other columns than name and enable sorting in the
dive site view.
Finally, don't cache the list of dive site names for the mobile app,
since that would also need some rather convoluted methods of keeping
the list up to date. Calculate it on the fly.

The (mis)uses the "LocationInformationModel". It moves the items

front and makes the others hidden.
Moreover, it was necessary to limit the geo-tag decoration role to

Replace UUIDs from LocationInformationModel and fix the fallout.
Notably, replace the UUID "column" by a DIVESITE "column".
Getting pointers through Qt's QVariant is horrible, we'll have
to think about a better solution.
RECENTLY_ADDED_DIVESITE now defines to a special pointer to
struct dive_site (defined as ~0).
This fixes an interesting logic bug:
The old code checked the uuid of the LocationInformationModel (currUuid)
for the value "1", which corresponded to RECENTLY_ADDED_DIVESITE.
If equal, currType would be set to NEW_DIVE_SITE. Later, _currType_
was compared against _RECENTLY_ADDED_DIVESITE_. This would only work
because NEW_DIVE_SITE and RECENTLY_ADDED_DIVESITE both were defined
as 1.

Access to dive-sites in the LocationInformationModel was via UUID.

Instead of having people treat latitude and longitude as separate
things, just add a 'location_t' data structure that contains both.
Almost all cases want to always act on them together.
This is really just prep-work for adding a few more locations that we
track: I want to add a entry/exit location to each dive (independent of
the dive site) because of how the Garmin Descent gives us the
information (and hopefully, some day, other dive computers too).

SsrfFilterSortProxyModel was a thin wrapper around QFilterSortProxyModel,
which was intended as a convenience class to avoid deriving from the
latter. The filter and sort functions were replaced by simple function
pointers.
Unfortunately, by using function-pointers, the whole thing was rather
weak as these functions do not have state. The last user was removed
in ac8dcd7f65b78958587ba025280ed4c529b0b519. Therefore, remove the

The location information shows a list of dive sites at the
same location as the edited dive site. This was done by passing
a function to an "SsrfSortFilterProxyModel". Unfortunately,
the latter does only support function pointers without state
and therefore had to access the global "displayed_dive_site"
object.
Replace the SsrfSortFilterProxyModel by a proper subclass of
QSortFilterProxyModel that contains information on the position
and id of the currently edited dive site.
Update the filter model if the location of the dive site changes.
This introduces a behavioral change: editing the GPS location
will lead to an updated list.

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.

Having random uuids seemed like a good idea, but there are several
situations where they really cause problems. One is merging dive file
imports from V2 logfiles. Another is testing such imports.
Instead of making the uuid random we now hash the name and add the
timestamp of the first dive associated with this dive site to the hash
(first in this context is "first encountered" with no guarantee that it is
the chronologically first). This way V2 imports create deterministic uuids
but uuid conflicts are still extremely unlikely, even if the user has
multiple dive sites with the same name.
