Found while compiled against Qt 5.10 build from source. The assert
Q_ASSERT(last >= first) is trapped by this beginInsertRows in
case there are no pictures. Just do not call this when there are
no pictures.

This implements different zoom levels for the dive photos tab as
suggested by Stefan Fuchs <sfuchs@gmx.de> in #898.
The zoom level can be changed using a slider or CTRL+mousewheel.
Zoom levels range from a third of the standard thumbnail size to
thrice the standard thumbnail size.
Thumbnails are cached in maximum resolution and scaled down on
the fly. Because the profile widget took its pictures from the
photo list model, an extra picture copy with a fixed size had
to be introduced.
The UI is still a bit crude.

It was only used by the DivePictureModel class, no need to export it.

Correct way of using indices for rowDDstart and rowDDend.
Reset rowDDstart and rowDDend at beginning of updating dive pictures.

In the dive picture tab show pictures of all selected dive.
But at the same moment take care that in the profile only
pictures from displayed_dive are displayed.

The thumbnailing in qt-models/divepicturemodel.cpp was performed
concurrently, but the thumbnailCache was not protected from races.
Resolve this by guarding the thumbnalCache accesses with mutexes.

The code of DivePictureModel used a QHash to keep track of thumbnails.
Not only was the code rather complex - it also had the consequence that
pictures are sorted according to the hash function, i.e. seemingly
random.
This commit replaces the QHash by a simple QList which keeps track
of thumbnails and some meta-data.

Note that constructs like QList<QFuture<void>> is incompatible with
pre-C++11 compilers. But the code base is so full of C++11isms that
we may just as well remove asymmetric eye-sores of the kind
"QList<QFuture<void> >".

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.

This drastically improves the time it takes to select a dive
with several pictures at the expense of longer startup and
bigger hash files.

This required a bit more untangling, but with this it seems we can build
subsurface-mobile again (at least on the desktop).
Interesting is the removal from inside the ImageDownloader of the call to
DivePictureModel::instance()->updateDivePictures() - which actually could
cause some interesting recursion issues. If it turns out we did indeed
need this, it needs to be re-architected.

Altering DivePicture model to allow deleting images
from the QListView without immediate updating of the
list. Updating is determined by an additioanl parameter

This model should be used inside the Edit Dive Site mode.
It should display all photos from all dives that are part
of this dive site, ignoring trips.

This class will surely be used on the mobile version, and it was very
tangled inside divepicturewidget.
