printGPSCoords() returned a newly allocated C-style string. Most
callers simply made a QString out of it and freed the C-style string.
This is paradoxical, as printGPSCoords internally works with QStrings
and converts them to C-style on return.
Therefore, let printGPSCoords() return a QString and create a
printGPSCoordsC() wrapper for the two C-callers.

The printGPSCoords() function returns a copied C-style string. Since
the owndership is transferred to the caller, the correct return type
is "char *" instead of "const char *".
Thus a number of casts when calling free can be removed.
Moreover a number of callers didn't free the string and thus were
leaking memory. Fix them. Ultimately we might want two versions
of the function: one for QString, one for C-style strings.

Since "struct dive_site *" is now a Q_METATYPE, the functions
MapWidgetHelper::centerOnDiveSite() and ::getCoordinates()
can directly get such a pointer instead of a QVariant. This
makes the code nicer to read.

Replace the UUID reference of struct dive by a pointer to dive_site.
This commit is rather large in lines, but nevertheless quite simple
since most of the UUID->pointer work was done in previous commits.

MapWidgetHelper::reloadMapLocations() used an array of uuids to
add dive sites to the map only once. Replace this by an array
of pointers. This is a small piece of a larger effort to remove
dive site UUIDs.

Replace UUIDs by pointers to dive-site in mobile code. In both
cases, the value is transported via a QVariant. The function
getCoordinatesForUUID(), which was only used from mobile, can
be replaced by a getCoordinatesFor() function taking a variant
supposed to contain a dive-site pointer. Likewise, the variant
of the centerOnDiveSite function is now supposed to wrap a
pointer-to-divesite.

There are two updateDiveSiteCoordinates() member-functions, viz.
in MapWidget and MapWidgetHelper. Adapt them to take a pointer
to dive_site instead of a UUID. This is part of an effort to
replace UUIDs by pointers.

Replace the uuid argument to MapWidgetHelper::enterEditMode() by a

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).

Commit 0aef04352a3210a6024f860758af466ea774dd5e made it impossible
to move new dive sites on the map. When entering dive-site-edit mode,
the filter would be instructed to show only dives of the corresponding
dive site [which didn't yet exist] and therefore all dive sites
on the map were deselected.
Fix this by explicitly centering on the dive site to be edited in
MapWidgetHelper::enterEditMode().
Fixes #1809

MapWidgetHelper::reloadMapLocations() reloads all dive flags
of the non-hidden dives plus the one of the currently edited
dive. Use the current_dive macro to determine whether this
is the current dive site instead of the global displayed_dive_site
object.
This is part of a series of commits, which makes the map-code
independent of the global displayed_dive_site object.

Instead of reading out the global object "displayed_dive_site",
pass the dive site to be edited in arguments to
prepareForGetDiveCoordinates() and enter edit mode.
Simplify the code in LocationInformationWidget by not using
signals to call the prepareForGetDiveCoordinates() function.
While doing this, collect common code in accept() and reject()
in the already existing resetState() function.
This is another entry in a series of commits that makes
data-flow more clear by removing access to the global
"displayed_dive_site" object.

The setEditMode(bool) function behaves very differently, when
entering and exiting edit mode. Therefore, split it in two
versions. This will allow to pass arguments that make sense
only when entering the edit mode.
Since setEditMode() doesn't exist anymore, turn the editMode
Q_PROPERTY line to the MEMBER version. Accordingly, remove
the reader function. If QML wants to enter edit mode, it
should invoke the appropriate function and not simply set
the flag.

The coordinates of a "dragged flag" were passed out-of-bound via
the global "displayed_dive_site" object and then a signal was sent
to notify of the changed coordinates.
Instead, pass the coordinates directly via the signal. This makes
the data- and control-flow more clear.

This was used by LocationInformationWidget to instruct the map
that the coordinates of the current dive site has changed.
There is no reason why this couldn't be a function call, as no
other object ever connect()s to this signal. In fact, such a
function already exists viz. updateLocationOnMap.
Therefore, replace the signal by a simple function call.
Moreover, the uuid and coordinates of the dive site were transported
via the global "displayed_dive_site" object. Instead, pass this
information in the parameters of the function. This makes it
easier to reason about data- and control-flow.

The dive site list was connected to centerOnDiveSite(). Apparently,
the currently selected dive site should have been shown in the map.
Yet, this never worked, because the actual dive site of the selected
dive had precedence in centerOnDiveSite().
It seems that centerOnDiveSite() had actually to purposes:
1) center on the passed in dive site
2) center on the dive sites of the selected dives
Therefore, split this function in two separate functions for
each of these use-cases. This allows us to remove some pre-processor
magic (mobile vs. desktop) and to remove a parameter from the
MainTab::diveSiteChanged() signal.

If the dive list is filtered the map should hide dive locations
that do not match the dive list filter.
To achieve that, loop over dives instead of dive sites in
MapWidgetHelper::reloadMapLocations() and discard
dives that are hidden by the filter. Then check if a dive
has a dive site attached to it and re-use the old functionality.

helpers.h included qthelper.h and all functions declared in helpers.h
were defined in qthelper.h. Therefore fold the former into the latter,
since the split seems completely arbitrary.
While doing so, change the return-type of get_dc_nichname from
"const QString" to "QString".

centerOnLocationHard() is added in MapPage.qml so that
on `firstRun` the map is hard panned to the desired location
without animation.
This affects the selection of a new "Dive details" -> "Map it" or
when opening a GPS location in the map.
The idea behind this change is to avoid starting the map animation
from an arbitrary location such as [0,0] or London. Also, to not
start the map zoomed out completely and then zoom in on a selected
dive.
For this change to work, add the helper getCoordinatesForUUID()
to qmlmapwidgethelper.cpp/.h and use it to obtain the
QGeoCoordinates for a dive site UUID.

The mobile version is limited as it does not support dive list
selection of multiple dives and editing multiple dives.
Also the dive list on mobile does not follow the same indexing as
the desktop version dive list.
Use the SUBSURFACE_MOBILE macro and for:
- centerOnDiveSite() either deselect map markers or center on
a single one (never on a rectangle like the desktop version)
- selectedLocationChanged() and selectVisibleLocations() return
a list of single dive ID

Once the user starts editing a dive site, make sure to pass
coordinates of either the current map center (if a new MapLocation
is being added) or the coordinates of the existing MapLocation.
The "Dive site management" coordinates text field would receive
these new coordinates after the displayed_dive_site struct
is updated and the coordinatesChanged() signal is emitted.

This patch allows updating the location of map markers
while editing a dive site and updating the text in the
LocationInformationWidget in real-time.
Currently it is only possible to see the marker changes by
clicking 'Apply'.
The modification required the following changes:
- add the MapWidget::updateCurrentDiveSiteCoordinatesToMap() slot
and call it each time the GPS text updates
- separate the updateCurrentDiveSiteCoordinates(FromMap/ToMap) logic
by having the FromMap/ToMap suffix to method names
- make MapWidgetHelper::updateCurrentDiveSiteCoordinatesToMap()
call a new MapLocationModel::updateMapLocationCoordinates()
method, which updates selected location coordinates and the model
- add MapLocation::setCoordinateNoEmit() that does not emit
a signal when updating a coordinate

When starting to edit a new dive location, create
a marker at the current map center instead of zooming
out and centering on the 0,0 coordinate.
This will help (and speed up) a lot the edition,
if the user needs to add numerous dive markers
at a specific location close to each other.

Move all the map widget platform agnostic files to the
<subsurface-root>/map-widget folder.
This avoids the confusion about the desktop version of subsurface
using mobile components. The map widget is planned as a shared
component between the mobile and desktop versions.
desktop-widgets/mapwidget[.h/.cpp] still remain as those are specific
to the desktop version.
