9efb56e2d4 introduced rather complex
logic for picture drag'n'drop events onto the profile. Among other
things, the code had to check whether the picture actually belongs
to the displayed dive.
This can be simplified by transporting the dive-id in the drag'n'drop
event structure. The flow goes like this:
DivePictureModel--(1)-->DivePictureWidget--(2)-->ProfileWidget
For (1), we can use the Qt::UserRole role. This was used to transport
the picture-offset, but this is not needed anymore since ProfileWidget
was decoupled from DivePictureModel.
For (2), we simply replace the "position" value, which was never used.
Why would the receiver care which pixel was pressed in the media-tab?
This commit also contains a minor cleanup in DivePictureWidget:
QListView::mousePressEvent(event) was called in both branches of an
if and can therefore be removed from the if. This is so trivial,
that it doesn't warrant its own commit.

9efb56e2d4 added code to rearrange
pictures on drag'n'drop. To keep the correct repainting order (i.e.
later thumbnails are painted on top of previous thumbnails), the
z-value was set accordingly. In principle a sound idea, but it did
not work out, because on hoverEnter and hoverExit events, the z-values
were modified, thus restoring the wrong drawing order.
Instead, use the QGraphicsItem::packBefore() function. Experimentation
showed that this only works if stacking is done from the back
of the list.

Gracefully handle drag & drop to the profile, which changes the
offset of the pictures. To do this, keep the pictures in the
DivePictureModel and the ProfileWidget2 sorted by offset and
re-arrange if needed to keep the list sorted. This needs some
code reshuffling.

If pictures were deleted, the remaining thumbails where staying at
their positions. Only when switching between dives, the new positions
were recalculated. Do the recalculation immediately. More precisely:
the x-coordinate, which is determined by the timestamp, stays identical.
Only the y-coordinate is recalculated such that overlapping of thumbnails
is avoided.

As long as ProfileWidget2 and DivePictureModel showed the same set of
pictures and any change would lead to a full recalculation of the set,
it made sense to let ProfileWidget2 use DivePictureModel's data.
Recently, keeping the two lists in sync become more and more of a
burden. Therefore, disconnect ProfileWidget2 and DivePictureModel. This
will lead to some code-duplication and perhaps a temporary drop in
UI-performance, but in the end the code is distinctly simpler and also
more flexible.
Thus, for example the DivePhotoTab could be changed to support headings
without having to touch ProfileWidget2 at all.

The DivePictureModel signals were connected int the setProfileState()
function of ProfileWidget2. If this function was called repeatedly
(e.g. after adding a dive), multiple connections were made, which led
to multiply delivered signals. This in turn led to confusion, when
deleting pictures (i.e. multiple pictures were deleted).
Instead, connect once in ProfileWidget2's constructor. It is unclear
whether these signals should be disconnected temporarily if no pictures
are shown. In any case, the weren't, so this shouldn't introduce any
regression.

In a recent commit, the profile widget was changed to reuse
DivePictureItems. This made toggling of picture-visibility
disfunctional, because the visibility was set in the constructor.
Only on change of dive would the setting take effect.
Therefore, move the setting of the visibility up to the
ProfileWidget2::plotPictures() call. This is more consistent
anyway, since at this level pixmap and fileUrl are set.

On deletion of a single or multiple pictures, the whole DivePictureModel
was repopulated, which was clearly visible in the UI, owing to the
reconstructing of all images in the profile plot.
To avoid this vexing behavior, implement proper deletion routines in
DivePictureModel and ProfileWidget2. Since this needs sensible erase()
semantics the QList<PictureEntry> member of DivePictureModel was
replaced by a QVector. A QVector should be the default anyway, unless
there are very specific reasons to use a QList (which actually is
a deque, not a classical linked list).

The function removePicture() had a flag "last", which would indicate
that the called had finished removing pictures. Only then would
the model be recalculated.
This is a strange interface and, matter of fact, the caller was buggy:
if the last picture to be removed didn't have a proper url, removePicture()
was never called with "last" being set.
Change the interface to take a list of pictures to be deleted. This
will allow us to make picture deletion smarter in follow-up commits.

If animDelete() was called with prefs.animation_speed == 0, the
object would not be marked for deletion, as opposed to calling
with prefs.animation_speed != 0. This would leak the objects.
Therefore delete the objects if called with prefs.animation_speed == 0.
The caller doesn't keep a reference to the objects. Therefore,
a plain delete is fine, as opposed to a deleteLater().

In MainWindow::current_dive_changed() first plotDive() is called,
which replots all the pictures by calling plotPictures(). This
is pointess, because it plots the pictures of the previous dive.
Then, updateDiveInfo() is called, which resets the dive pictures
and automatically replots them. Thus, switching between dives
both with hundreds of pictures is way slower than necessary.
Switching the plotDive() and updateDiveInfo() calls doesn't work.
The reason is not 100% clear, but it doesn't make sense to plot
pictures of the new dive as long as the profile still shows the
old dive anyway.
As a quick-fix, add a flag to plotDive(), which tells the function
to clear the pictures list instead of redrawing it.
Ultimately, plotDive() should probably be split in two functions.
One for the callers who update the pictures themselves and one
for the others.

The recent simplification of the close button code introduced a crash:
Deletion of pictures caused an invalid memory access, because the
CloseButtonItem was deleted with the parent DivePicture item.
For some (not fully understood!) reason, a reference to this button
was stored in the depths of Qt.
Empirically, it was found out that removing the first line of the pair
QGraphicsItem::mousePressEvent(event);
emit clicked();
fixed the crash.
It seemed therefore prudent to remove the whole questionable signal/slot
mechanism and directly call the removePicture() function of the parent.
Thus, the intermediate DiveButtonItem class became unnecessary and was
removed, leading to a shallower class hierarchy.
Unfortunately, CloseButtonItem must still be derived from QObject owing
to the Q_PROPERTY machinery, which is in turn needed for animation.
To make this compile on mobile, the conditional compilation of
removePicture() (#ifndef SUBSURFACE_MOBILE) was removed. After all,
if DivePixmapItem is used, there are pictures, so removePicture()
should be functional. Conditional compilation should concern the
whole class, not only this function.

This provides for reading of divemode change events from dive logs
and for writing them to dive logs. This applies to xml and git
divelogs. Divemode change events have the following structure:
event->name = "modechange"
event->value = integer corresponding to enum dive_comp_type (dive.c),
reflecting the type of divemode change (OC, CCR, PSCR, etc).
In the dive log file, the event value is written as a string that
corresponds to each of the enum values, e.g.
<event name='modechange' divemode='OC' />
This xml is also read from the dive log file and translated to an
appropriate value of event->value.
The file diveeventitem.cpp was udated to reflect this new way of
dealing with divemode change events.

fake_dc() used to return a statically allocated dc with statically
allocated samples. This is of course a questionable practice in
the light of multi-threading / resource ownership. Once these
problems were recognized, the parameter "alloc" was added. If set
to true, the function would still return a statically allocated
dc, but heap-allocated samples, which could then be copied in
a different dc.
All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does
not care about the samples, it can simply reset the sample number
to zero after work.

This commit allows plotting the OC-equivalent pO2 graph for PSCR
dives. This happens in both the cases where there is no external
O2-monitoring AND when there is external pO2 monitoring. The
calculations are only done for PSCR dives and is achieved as
follows:
1) Within plot-info create a pressure-t called OC_pO2 in
profile.h and populate this variable with the open-circuit
pO2 values in profile.c.
2) Create a new partialPressureGasItem ocpo2GasItem in
profilewidget2.h and, in profilewidget2.cpp, initialise it
to read the plot-info OC_pO2 values and enable its
display by using the setVisible method. The
diveplotdatamodel was also touched in order to achieve
this.
3) Create a pref button that controls the display of OC-pO2 for SCR dives
4) Change the colour of the OC-pO2 grpah to orange
5) Change the connection of the crr_OC_pO2 signal to be appropriate
6) rename the OC_pO2 attribute to scr_OC-pO2

Only update those pictures of the DivePictureModel that actually changed.
This will be useful once pictures are loaded incrementally.
To do so, replace the pictures array by an array with stable ids. Before
this commit, not-shown pictures are left out of the pictures array, which
makes the mapping from DivePictureModel-ids to the picture array index
non-trivial.
Replace the QList<DivePictureItem *> by a std::vector<std::unique_ptr<DivePictureItem>>
to ease memory management. Sadly, owing to COW semantics, QVector is incompatible
