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.
Replace this by a direct access to the struct dive_site pointer.
Accordingly, rename the UUID_ROLE to DIVESITE_ROLE.
This is a small step in replacing dive-site UUIDs by pointers
throughout the code base.

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).

Instead of having people treat latitude and longitude as separate

This is really just prep-work for adding a few more locations that we

The DiveItem and TripItem classes were wrappers around dive * and
dive_trip * used to extract tabular data. With the rework of
DiveTripModel they lost all their state besides the pointer itself.
The usage was:
DiveItem item(d);
item.data(...);
This can now be simplified to the much more idiomatic
diveData(d, ...);
and analoguously for TripItem.
While adapting the data() function to be part of DiveTripModel, change
the
QVariant ret
switch(...) {
...
case ...:
ret = ...;
break;
...
}
return ret;
style to
switch(...) {
...
case ...:
return ...;
}
Not only is this shorter and easier to reason about, it generally also
improves the generated code. The compiler can directly construct the
return value in the buffer provided by the caller. Though modern
compilers start to be very good at avoiding unnecessary copies.
In total this cleanup results in a net-reduction of 190 lines of code.

Comits f427226b3b and 43c3885249 of the undo series introduced 2 calls
of autogroup_dives() without checking the autogroup global boolean.
This is a bug. An import from DC (for example) then triggers an
autogrouping, the divelist is autogrouped, and the UI button
is off.
This commit solves this. I've chosen for a guard in the autogroup_dives()

In additon, simplified the other calls to this function, as we do

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?

SsrfFilterSortProxyModel was a thin wrapper around QFilterSortProxyModel,

latter. The filter and sort functions were replaced by simple function

Unfortunately, by using function-pointers, the whole thing was rather
weak as these functions do not have state. The last user was removed

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

Planned dives were still added by directly calling core code.
This could confuse the undo-machinery, leading to crashes.
Instead, use the proper undo-command. The problem is that as
opposed to the other AddDive-commands, planned dives may
belong to a trip. Thus, the interface to the AddDive command
was changed to respect the divetrip field. Make sure that
the other callers reset that field (actually, it should never
be set). Add a comment describing the perhaps surprising
interface (the passed-in dive, usually displayed dive, is
reset).
Moreover, a dive cloned in the planner is not assigned a
new number. Thus, add an argument to the AddDive-command,
which expresses whether a new number should be generated
for the to-be-added dive.

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
divelist, but it turned out that this was suboptimal, because
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.

The command-objects select a current item, but this selection
was not propagated to the front-end. The current item is the
base for keyboard-navigation through the dive-list and therefore

Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.
The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
DiveTripModel indexes to actual indexes via its QSortFilterProxy-
model.
For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.
To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.
Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

Don't delesect dives, when unregistering them from the backend.
If a previously selected dive is added, select it in the dive-list.

is called for each of them, making this very slow. This will have
to be fixed in subsequent commits.

Previously, each dive-list modifying function would lead to a
full model reset. Instead, implement proper Qt-model semantics
using beginInsertRows()/endInsertRows(), beginRemoveRows()/
endRemoveRows(), dataChange().
To do so, a DiveListNotifer singleton is generatated, which
broadcasts all changes to the dive-list. Signals are sent by
the commands and received by the DiveTripModel. Signals are
batched by dive-trip. This seems to be an adequate compromise
for the two kinds of list-views (tree and list). In the common
usecase mostly dives of a single trip are affected.
Thus, batching of dives is performed in two positions:
- At command-level to batch by trip
- In DiveTripModel to feed batches of contiguous elements
to Qt's begin*/end*-functions.
This is conceptually simple, but rather complex code. To avoid
repetition of complex loops, the batching is implemented in
templated-functions, which are passed lambda-functions, which
are called for each batch.

AddDivesToTrip, CreateTrip, AutogroupDives, RemoveAutogenTrips
and MergeTrips basically all did the same thing as RemoveDivesFromTrip,
which was already implemented. Thus, factor our the common functionality
and hook it up to make all these functions undo-able.
Don't do the autogroup-call everytime the dive-list is rebuilt
(that would create innumberable undo-actions), but only on dive-load /
import or if expressly asked by the user [by switching the autogroup
flag].

The dive list is fed data by means of a sorted "DiveTripModel".
There are two modes: list and tree. This was implemented rather
elegantly with a general "TreeModel", which can represent trees
of arbitrary depths.
Nevertheless, we have at most two levels and on the second level
only dives can reside. Implementing proper model-semantics
(insert, delete, move) will be quite a challenge and implementing
it under the umbrella of a very general model will not make it
easier.
Therefore, for now, hardcode the model:
At the top-level there are items which may either be a trip
(can contain multiple dives) or a dive (contains exactly one dive).
Thus, we can completely de-virutalize the DiveItem and TripItem
classes, which are now trivial wrappers around dive * and dive_trip *.

The undo-system now guarantees that pointers to dives are stable

Dives were directly imported into the global dive table and then

by passing an independent dive table.
The dive table of the to-be-imported dives will be sorted and merged.
Then each dive is inserted in a one-by-one manner to into the global
dive table.
This actually introduces (at least) two functional changes:
1) If a new dive spans two old dives, it will only be merged to the
first dive. But this seems like a pathological case, which is of
dubious value anyway.
2) Dives unrelated to the import will not be merged. The old code
would happily merge dives that were not even close to the
newly imported dives. A surprising behavior.

process_dives() is used to post-process the dive table after loading

Especially in the light of undo, load and import are fundamentally
different things. Notably, that latter should be undo-able, whereas
the former is not. Therefore, as a first step to make import undo-able,
