The dive-site line edit box features two special entries for adding
new dive sites. These should display different texts depending on
whether the current dive has a dive site or not.
The current check is wrong, because it used displayed_dive, but
since the last set of undo-changes, this might not be filled out
correctly anymore. Instead the code should check the actual current
dive.

In the edit-dive-site tab the filter is switched to a particular
mode where only dives at that site are shown.
If we want to reuse this for the dive-site tab the mode has to
be extended to allow for multiple dive sites. This is trivially
done by replacing a pointer by a vector of pointers.

As long as a text field is active, CTRL-Z only affects this field.
Thus it is suprisingly hard to undo edits. There seems to be a
fundamental problem with CTRL-Z handling.
To make it somewhat easier, catch any ESC-key event and move the
focus to the MainWindow. This effectively removes the focus from
any text field.
This all appears very wrong, but so far I wasn't able to find the
root cause of the problem.

The signal was caught by the MainWindow to:
1) call setDefaultState()
2) call refreshDisplay()
3) call refreshDisplayedDiveSite()
1) Let's call that directly from the widget. The reason is that in
the future there might be multiple way to get into the widget and
therefore the widget needs finer control.
2) Remove this call as it produces an unsteady UI.
3) This should be done by undo commands, not only when finishing
dive site editing.
Thus, the signal becomes unnecessary and can be removed.

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.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

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.

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.

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?

The dive-site-edit widget uses a copy of the to-be-edited site

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

Under certain conditions the user was presented an ugly
"invalid dive site" message. The condition would arise because
the proxy-model which selects the list of dive sites and the code
which creates a proposed dive site name had different filter
conditions:
- The proxy would select any dive site containing the text
- The name-proposing code searched for dive sites *starting*
with the text.
If the user entered a text contained by a dive site name, but
no dive site would start with the second line was filled with
a dummy text. This text would be kept if it contained the text
entered by the user.
To avoid this problem, if no dive site is found, use an empty
string instead. This will be filtered out by the proxy because
it does not contain the user-entered string.
Yes, that's horribly subtle, therefore add a comment. But ultimately,

2) center on the dive sites of the selected dives
