To make data flow more clear, unglobalize the downloadTable object.
Make it a subobject of DownloadThread. The difficult part was making
this compatible with QML, because somehow the pointer to the
download-table has to be passed to the DiveImportedModel. Desktop would
simply pass it to the constructor. But with objects generated in QML
this is not possible. Instead, pass the table in the repopulate()
function. This seems to make sense, but for this to work, we have to
declare pointer-to-dive-table as a Q_METATYPE. And this only works
if we use a typedef, because MOC removes the "struct" from "struct
dive_table". This leads to compilation errors, because dive_table is
the symbol-name of the global dive table! Sigh.

To not have to bother with memory-management. Moreover, the
old code was in principle wrong, since it assumed that
sizeof(bool) == 1. Of course, this is true for all supported
platforms, but let's not depend on such implementation-defined
behavior anyway.

This function resets the DiveImportedModel. It takes two
arguments: first and last index. All callers passed in 0
and number-of dives anyway, so remove the arguments.
Since this now does the same as repopulate(), merge the
two functions.
Moreover, implement Qt-model semantics by using a
beginResetModel()/endResetModel() pair. This simplifies the
code.

The idea is that this struct will have all the needed data
that will be passed to the filter model. Everything that happens
on the filterwidget will fill out this struct, then forward it
to the model, that in turn will activate the filter hiding
some of the dives that matches on your divelist.

Commit 911edfca712a046944de6d033cc4b8dd50cedfc3 changed the dive list
on desktop to update positions of trips when adding/removing dives.
A very unlikely case, but necessary for consistency.
For a trip to be moveable down, its index has to be one-less than
the maximum index, which is "items - 1". The code was doubly wrong:
it forget the "1" and checked for less-or-equal instead less-than.
Thus this was effectively an off-by-two error. Fix it.

QML's ListView uses the "section" property to test if items belong to the
same section. Apparently, this must be a string and therefore we can't
pass e.g. a dive-trip object. Therefore a specially formatted string
was passed in, which was guaranteed to be unique (contained the dive-trip
pointer value) and the fully formatted trip-title and short-date.
The disadvantage of that approach is that the formatting is performed for
every dive and not every trip. Perhaps not a problem now, but it makes
it for example necessary to cache the number of filtered dives.
To be more flexible, pass in only the pointer value formatted as
hexadecimal string and provide a function to convert that string
back to a trip-pointer (in the form of a QVariant, so that it can
be passed to QML). Moreover provide two functions for formatting the
title and the short-date.
The three new functions are members of DiveListSortModel. This might not
be the perfect place, but it is easy to reach from the DiveListView.

To make sorting more controlled, move all sorting functions into
the core. For this, introduce a "dive_or_trip" structure, which
represents a top-level item. Adapt the DiveTripModel accordingly.
There are now three sorting functions:
1) dive_less_than
2) trip_less_than
3) dive_or_trip_less_than
These should be used by all sorting code. By moving them to a
single place, the mess can hopefully be cleaned up.

Traditionally, the DiveTripModel has its data sorted in opposite
direction to the core-data (chronologically descending vs. ascending).
This bring a number of subtle problems. For example, when filling
the model, trips are filled according to the *last* dive, whereas
later insertion points are according to the ->when value from the
core, which depends on the *first* dive.
As a start of fixing these subtleties, change the sort direction
to reflect the core-data. Ideally, this should lead to a removal
of the redundant data-representation.
Since the model is now sorted in ascending order, sorting has to
be enabled in the DiveListView constructor to reflect the
default-descending order.

The old code always sorted by "ascending" by default. But
because users typically want their new dives top, "ascending"
was defined for NR and DATE, such that it is actually descending.
Turn these around and intitialize these two fields as
default-descending.
This is possible using the Qt::InitialSortOrderRole role
in DiveTripModel::headerData().

The dive list was sorted using the default-sorter of
QSortFilterProxy model. This is mighty inflexible as it
considers only one column. This has the funky effect that
for rows with identical elements, the sort order depends
on the previous sorting.
Implement a lessThan() function in the MultiFilterSortModel,
which simply hands the sorting down to the actual model.
This might be considered a layering violation, but it makes
things so much easier.
Sadly, it seems like the column-to-be-sorted is transported
in the provided indices. Therefore, the comparison is chosen
using a switch for *every* comparison. It would seem much
more logical to set a function pointer once and use that.
Further investigations are necessary.

The data-flow from C-core to list-view is as follows:
C-core --> DiveTripModel --> MultiSortFilterModel --> DiveListView
The control-flow, on the other hand, differs as DiveListView
accesses both MultiSortFilterModel and DiveTripModel, whereas
MultiSortFilterModel is mostly unaware of its source model.
This is in principle legitimate, as the MultiSortFilterModel might
be used for different sources. In our particular case, this is
not so. MultiSortFilterModel is written for a particular use case.
Therefore, model control-flow follow after data-flow: Let MultiSortFilterModel
set its own source model and DiveListView access the MultiSortFilterModel,
which then manages its source model.
This is not bike-shedding, but will enable a more flexible and
higher-performance sorting.

There was this ugly pattern of passing pointers-to-dive_site via
a QVariant of void * type. This is of course inherently unsafe.
Pass these pointers using their proper types instead. This makes
it necessary to register them in Qt's meta-type system. Doing so,
fixes a bug: QML couldn't call into updateDiveSiteCoordinates()
because it didn't know the type and thus the coordinates of
the moved flag were not reflected in the divesite-dialog.

To test whether to show a dive, the UUIDs of the filtered-by
location and the dive-site of a dive were compared. Since UUIDs
are unique (as the name implies), directly compare pointers.
Note: this code comes from a time when the filtered-by location
was not a pointer, but a copy.
Moreover, the if tested first for the same name, then (logical-or)
for the same uuid. This makes no sense, as the same dive-site
implies the same name. This code likewise can be explained by
historic reasons: the filtered-by location may have contained
a different name. Swap the order of the conditions: first test
for the same object and only of the objects differ, test for
the same same.

This is another case of a weird pattern where an object would
connect it's own signal to the slot of a different object.
There seems to be no reason why the former couldn't simply
call the latter.
Remove the [start|stop]FilterDiveSite signals of LocationInformationWidget
and call the corresponding functions of MultiFilterSortModel directly.
While doing so, replace the UUID argument by a pointer-to-divesite.

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.

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).

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 43c3885249f 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()
that now is a no-op when called when the user did not select autogrouping.
In additon, simplified the other calls to this function, as we do
not need to check before calling any more.

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,
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

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.
