A user reports a SIGSEGV that points to DownloadFromDCWidget::updateProgressBar()
in relation to strlen()/strdup(), at end of download. Reading the code, as I
can't reproduce the crash, it seems that the progress_bar_text is set to NULL
and later strdup-ped. The man page is not fully clear on this, but setting it
to the empty strings is much safer.
Might fix: #507

The C++ side for the desktop version already does that. Add a slot

The editing support is added via dragging. It is handled via the
MouseArea's drag.target of the MapQuickItem. The drag target changes
with the model selectedUuid.
"mapAnimationZoomIn" now also does an initial zoom-out before moving
to a new location.
centerOnCoordinate() now pefroms calculations to determine how much
the animation needs to zoom out. What it does is it reduces the Map
zoomLevel util both the current and the new target coordinates are visible.
It then restores the zoomLevel and performs animation based on newZoomOut.
animateMapZoomIn() is now obsolete.
The patch also includes the following smaller changes:
- remove the setSelectedUuid() call in deselectMapLocation()
This is now handled in C++
- sets "defaultZoomIn" to 12.0
- use ">=" when determining if a mapItem text should be visible

The local slot coordinatesChangedLocal() tracks the MapWidgetHelper
coordinatesChanged() signal and emit a coordinatesChanged() signal
to any listeners (e.g. MainWindow).
Also add a small change in centerOnDiveSite(), to not be called if
we are skipping the reload (skipReload is updated by
selectedDivesChanged()).

updateCurrentDiveSiteCoordinates() should be called from
QML when a marker changed it's location. it emits the coordinatesChanged()
signal, which should be tracked in the MapWidget class. The MapWidget
class should emit the same signal to the MainWindow (Marble does that).
editMode is now a boolean property, which should put the QML map into
editing mode.

The marble globe tracks dive sites with the same name and discards
such that are less than 50 meters apart.
We already store names in MapLocation objects, but using a
QMap<QString, MapLocation *> to check the names is probably faster
with the expense of using more memory.

Call setSelectedUuid() from C++ also center on coodinates instead

The MapItemView delegate now includes a white Text element.
It uses the MapLocation "name" property as text.
This text is only visible if the map zoom is above "textVisibleZoom".
For hundreds of dives, using the DropShadow effect for the text
makes it laggy. Instead, using a fake drop shadow (duplicate black
Text under the default text) makes it much better.

This guard is to prevent a meaningless reload on the map marker list,
when the user selects a new dive and nearby dives. The flag is updated
in selectedDivesChanged() which on it's now cannot possibly trigger
changes in the markers, only the selection. The selection of active flags
is already handled by the model and automatically updated in the QML.

The selectedDivesChanged() signal from MapWidgetHelper is connected
to a local slot. One problem here is that this crashes with the calls to
DiveListView().
The dive list widget triggers events that call reload() on the MapWidget
(same happens for Marble's Globe class) and that crashes somewhere in
the QML shared library. TODO: investigate.

The signal emits a QList<int> filled with dive idexes from the
main backend dive table.
The MapWidgetHelper QML instance handles that in onSelectedDivesChanged().
This will only be needed for the mobile version, as the desktop version
should connect it's own slot in MapWidget.cpp.

Based on a current location (MapLocation), iterate the dive list
and add nearby dives (distance smaller than m_smallCircleRadius) to

The idea of this flag is to be able to only to emit the
selectedLocationChanged() signal when the user clicked on the map
(fromClick == true).
MapWidgetHelper::selectedLocationChanged() listens for this signal
and only then it will select nearby dives based on a "small-cicle".
If "fromClick" is false, it's the backend or the dive list that
updated the selection and MapWidgetHelper::selectedLocationChanged()
should no be called.

Each time the zoom changes MapWidgetHelper::calculateSmallCircleRadius()
is called, and the "small circle" radius is stored in both C++ and QML.
On the C++ side this radius will be used to select multiple nearby
dives.
Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
Based on a QGeoCoordinate, calculateSmallCircleRadius() calls
some QML Map methods to obtain how big a circle is in meters if
a circle is drawn over the Map widget with radius SMALL_CIRCLE_RADIUS_PX
pixels.
This is called a "small circle" of a sphere:
https://en.wikipedia.org/wiki/Circle_of_a_sphere
This "small circle" radius becomes huge if the map is zoomed out, while
quite small if the map is really zoomed in.
The idea behind this circle is to be able to select multiple nearby dives,
when clicking on the map (TODO).

The actionSelected() signal is now dispatched when the user selects
an action from the menu (see the "actions" object). Then the declaration
of the MapWidgetContextMenu object in mapwidget.qml can catch that
signal in the onActionSelected() slot and obtain the action via
switch() branching.
The actions enumeration is kept in QML for now, with the idea that
specific C++ methods from the mapwidgethelper class will be called
directly (if marked as Q_INVOCABLE), instead of a generic
onMapAction(action) C++ method in the helper. But if the actions
are possible from QML (like copying to clipboard) and are also
small and non-expensive, it might be better to keep them
in mapwidget.qml.

- move the readonly properties near the top of the root Item

NOTES:
- the ListView object uses lsitItemDelagate to display all elements from
the model listModel
- onCountChanged() is used to adjust the x position based on the
maxItemWidth property which is calculated when the items are populated
with text
- onVisibleChanged() is used to deselect the last selected item by
calling listModel.selectedIdx = -1
- onOpacityChanged() i sued to make sure that the View is hidden if the
opacity becomes 0.0
- inside the View there is a MouseAre which obtains the selected item via
indexAt(x,y)
- there is a Timer with id listViewVisibleTimer, which is called each
time the user selects an item from the list and the timer performs a
"delayed hide"
- a couple of State and a Transition objects are used to preform smooth
fade-in / out animation when the ListView is hidden or becomes visible

This property would act like a state flag. If -1 (default) no QML State
animation will be pefromed, otherwise the ListView will either fade in

The ListView delegate is a simple Component with a parent Rectangle.
It contains a text field with the ListView action.
This patch also defines some properties for the delegate animations
and looks. The property maxItemWidth tracks the width of all item
text, and makes the width of all items be of that value.
The above prevents potential issues when a fixed width item is used
and some translated language string cannot be fit inside of it.

Make the "enumeration" local to the Map object for now.
This will possibly break if another plugin is used in place of the
ESRI plugin, but it will simplify the map toggle button which is about
to be implemented next.
If support for multiple plugins is added on runtime a simple
helper function will be needed that will check the current plugin "name".
And return the appropriate supportedMapTypes[X] for e.g. STREET of that
plugin.

The animation sequence when deselecting a zoomed in map location, should
be:
- zoom out completely
- pan to center
To achieve that a new animation object is created - "mapAnimationZoomOut"
The previous zoom in animation is renamed to "mapAnimationZoomIn".
The map functions centerOnMapLocation() and deselectMapLocation()
now call the helper functions animateMapZoomIn() and animateMapZoomOut().
