This is a rather long commit, because it refactors lots of the event
code from pointer to value semantics: pointers to entries in an
std::vector<> are not stable, so better use indexes.
To step through the event-list at diven time stamps, add *_loop classes,
which encapsulate state that had to be manually handled before by
the caller. I'm not happy about the interface, but it tries to
mirror the one we had before.

This is a hairy one, because the sample code is rather tricky.
There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.
Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().
Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

Use more C++ style memory management for plot_info: Use std::vector
for array data. Return the plot_info instead of filling an output
parameter. Add a constructor/destructor pair so that the caller
isn't bothered with memory management.
The bulk of the commit is replacement of pointers with references,
which is kind of gratuitous. But I started and then went on...

Currently, the "hide event" status is lost when switching dives.
Save it in the event struct instead to make it persistent.
In the future we might save this information to the log file.
Then this should be integrated in the undo-system.
This commit also makes the "unhide events" menu entry more
fine grained: It now differentiates between individual
events and event types.
Note this adds an additional field to the event structure.
There is a "deleted" field that is used internally for
book-keeping, but probably should be removed. Not touching
this at the moment as long as this is C-only code. When/if
switching to C++ we can make the event linked list a table,
which will make this much simpler.

Currently the event type code uses libdivecomputer's flags
to differentiate between events. Make this explicit and extract
the event severity.
The reason is that later we want to be more explicit about showing/
hiding events and thereto we must format the name of events.
Moreover, this encapsulates the complexities of extracting
the severity in the event code (that used to be in the profile
code).

Reinstate the hiding of events by event type across
all dives in the log. This was unintentionally removed in #3948.
Also change the event type to be specific to name and severity, and fix
bug causing 'Unhide all events' to not show when only individual events
were hidden.
This still leaves the inconsistency that hiding of similar events is
persisted across the switch between dives, but hiding of individual
events is lost when switching dives, which is mildly confusing.

This was used to animate the position of the dive event items
when the size of the axis changed. However, that doesn't work
since quite some time. The axes size are changed when
1) switching dives
2) resizing the drawing area
In the first case, the dive event items are fully recalculated.
In the second case, animation speed is set to instant, since
resizing of windows is done continuously on any reasonably
modern desktop anyway. It might make sense on mobile, where
size changes are discontinuous, but there we use static
profiles anyway. Moreover, I checked a few applications and
none of them had animations when switching orientation of
my tablet.
Let's just remove this disfunctional thing and replace it
later, should someone complain.

The DivePlotDataModel was saved with every event to access the
depth. However, since the depth never changes, we can simply
save the depth instead.
Also, since we only need the model to access the plot_info,
pass the plot_info directly. As noted in a previous commit
message, I believe that Qt models are a very bad choice
for intra-application data transfer. They should only ever
be used to interface with Qt.
And since touching this code, pass duration_t instead of int
to depthAtTime() to make the callers less cluttered.

The printFontScale is used to scale up fonts (and icons) when

The DiveEventItem had an internal copy of the event. It passed
that copy to the undo-machinery, which of course didn't work.
Simply keep a pointer to the event. All changes to a dive no

so this should be safe.

When populating the events of a profile, a pointer to the current
gasmix was passed around to properly calculate isobaric_counterdiffusion.
The DiveEventItem::setupToolTipString() function updated this gasmix
when processing gas change events.
I inadvertently broke the code when replacing gasmix-pointers by
values. We could of course simply revert this part of the commit.
However, the data flow was horrible anyway: for example is supposed
that the setup functions were called in the correct order (i.e.
DiveEventItem::setupToolTipString() is called after all other
functions using the gasmix). Not exactly easy to follow.
Therefore, keep passing around the gasmix as value to make it clear
that the functions don't modify it. Keep the gasmix up-to-date at
the caller's site in ProfileWidget2::plotDive().

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

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.

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.
