cc225a44f2 Preferences: set deco parameters correctly enabled
And fix another bug in this area of the code. It appeared that
the gflow/gfhigh and conservatism deco parameters where not
enabled at startup, but after toggling the VPM vs BUEHLMANN setting
they were.

So, fix this as well.

ac9bab7e2f Autogroup only when selected
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()
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.

78e2560296 Cleanup: Turn widget accessor-functions into simple pointers
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?

In the dive-site-edit widget, a copy of the current dive site was

a823974b70 Dive site: don't use displayed_dive_site to store GPS coordinates
The displayed_dive_site object is used in the dive-site-edit widget
to store the old (before-edit) data. But it was also used to store
the GPS data when changed on the map or the input box. Very confusing.
Instead, use the text field as only authoritative source of the

of the GPS text field, update the list of dive sites at the same
position.

8815f77ea0 Dive site: use own copy of taxonomy in dive-site-edit widget
The dive-site-edit widget uses a copy of the to-be-edited site
to compare with old values. Generally, this seems overkill
(the original dive-site can be used for such a comparison).
But one place where it can't simply be removed is the taxonomy,
because the widget needs a place to store the unsaved data.

Change the code to use an explicit taxonomy structure instead
of the one provided in the copy. This should ultimately allow
removal of the latter.

f39596df06 Map: remove access to displayed_dive_site in GPS-filter model
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.

that the coordinates of the current dive site has changed.
There is no reason why this couldn't be a function call, as no

Therefore, replace the signal by a simple function call.

information in the parameters of the function. This makes it
easier to reason about data- and control-flow.

ce8199cdfd Cleanup: remove ReverseGeoLookupThread
Fetching the taxonomy from GPS coordinates was implemented in
a QThread. But the only access to the main function was a
direct call to run(). Thus, the thread was *never* started.
The function call was always asynchronous [it was using an
event loop though, so the UI doesn't hang]. Notably this
means that the signals connected to the thread would never
fire. And the spinner would never be activated.

Thus:
1) Turn the thread into a simple function.
2) Remove the spinner.

b19adecb9f Undo: make adding of planned dive undo-able
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.

7067e33596 Undo: select dives after add, remove, merge, split dive commands
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.

23db0ba68d Dive list view: replace signal-magic by flag
In DiveListView, we have a very fundamental problem: When
On the one hand, we get informed of user-selection in the
DiveListView::selectionChanged() slot. This has to set the
correct flags in the C-backend.

On the other hand, sometimes we have to set the selection
programatically, e.g. when selecting a trip. This is done
by calling QItemSelectionModel::select().

But: this will *also* call into the above slot, in which
we can't tell whether it was a user interaction or an
internal call. This can lead to either infinite loops or
very inefficient behavior, because the current dive
is set numerous times.

The current code is aware of that and disconnects the
corresponding signal. This is scary, as these signals are
set internally by the model and view. Replace this
by a global "command executing" flag in DiveListNotifier.
The flag is set using a "marker" class, which resets the flag
once it goes out of scope (cf. RAII pattern).

In DiveListView, only process a selection if the flag is not
set. Otherwise simply call the QTreeView base class, to reflect
the new selection in the UI.

To have a common point for notifications of selection changes,
add such a signal to DiveListNotifier. This signal will be
used by the DiveListView as well as the Command-objects.

ec7d85835f Dive list: implement proper Qt-model semantics for DiveTripModel
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.

6ac4ddbeed Core: introduce insert_trip_dont_merge() function

Therefore, add an insert_trip_dont_merge() function, which
adds the trip, but doesn't merge.

43c3885249 Undo: isolate undo-commands
This refactors the undo-commands (which are now only "commands").

- Move everything in namespace Command. This allows shortening of
  names without polluting the global namespace. Moreover, the prefix
  Command:: will immediately signal that the undo-machinery is
  invoked. This is more terse than UndoCommands::instance()->...
- Remove the Undo in front of the class-names. Creating an "UndoX"
  object to do "X" is paradoxical.
- Create a base class for all commands that defines the Qt-translation
  functions. Thus all translations end up in the "Command" context.
- Add a workToBeDone() function, which signals whether this should be
  added to the UndoStack. Thus the caller doesn't have to check itself
  whether this any work will be done. Note: Qt5.9 introduces "setObsolete"
  which does the same.
- Split into public and internal header files. In the public header
  file only export the function calls, thus hiding all implementation
  details from the caller.
- Split in different translation units: One for the stubs, one for
  the base classes and one for groups of commands. Currently, there
  is only one class of commands: divelist-commands.
- Move the undoStack from the MainWindow class into commands_base.cpp.
  If we want to implement MDI, this can easily be moved into an
  appropriate Document class.

f427226b3b Undo: make diverse trip-related operations undo-able
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].
