This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take
const pointers.
This concerns functions taking pointers to events and
the fallout from making these const.
The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.
Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.
Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

There were two functions for getting gas-mixes at a certain timestamp:
- get_gasmix() for repeated queries.
- get_gas_at_time() for a single query.
Since the latter is a special case of the former, simply call
the former in the latter. Moreover, rename to get_gasmix_at_time()
for consistency.
Replace on get_gasmix() call, which was outside of a loop by the
corresponding get_gasmix_at_time() call.

Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.
Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.
On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.
On 32-bit systems a pointer to the struct to be filled out will be
passed.
Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

Commit df156a56c0 replaced "virtual"
by "override" where appropriate. Unfortunately, this had the
unintended consequence of producing numerous clang warnings. If
clang finds a override-modified function in a class definition,
it warns for *all* overriden virtual functions without the override
modifier.
To solve this, go the easy route and remove all overrides. At least
it is consistent.

The keyword "virtual" signalizes that the function is virtual,
i.e. the function of the derived class is called, even if the
call is on the parent class.
It is not necessary to repeat the "virtual" keyword in derived
classes. To highlight derived virtual functions, the keyword
"override" should be used instead. It results in a hard compile-
error, if no function is overridden, thus avoiding subtle bugs.
Replace "virtual" by "override" where appropriate. Moreover,
replace Q_DECL_OVERRIDE by override, since we require reasonably
recent compilers anyway. Likewise, replace /* reimp */ by
"override" for consistency and compiler support.

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.

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.

PP_GRAPHS_ENABLED is only used in profilewidget2.cpp
make local to profilewidget.cpp
Signed-off-by: Jan Iversen <jani@apache.org>core/profile: move PP_GRAPHS_ENABLED from pref.h
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.
