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]).

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.

One close-button object was used for all dive pictures. This seems
like a brittle premature optimization and the pixmap is shared
anyway. Make the button a subobject of the dive picture object.
Change the object-hierarchy to be based on QGraphicsItem instead
of QObject. The QObject here is only used as a kludge to support
signals and properties (the latter are necessary for animations).
Remove a comment, which does not seem to be relevant after this
change.

Add an exclamation mark in the gas change icons if
the change violates our isobaric counter diffusion
criterium.

Tank icons were shown at incorrect spots on the profile
when the DiveEventItem object held a pointer to a struct
event even after the struct event at that address had
been freed. When internalEvent is a pointer to freed
memory, internalEvent->time.seconds could have all kinds
of crazy values, which get used in member function
DiveEventItem::recalculatePos to place the tank at bad
x coordinates.
The DiveEventItem(s) no longer store a pointer to memory
that they do not own. This way, no matter how the path of
execution arrives into slot recalculatePos, we never need
fear that the DiveEventItem will dereference a garbage
pointer to a struct event.

The reason for that is, even if profile widget is made with qpainter
and for that reason it should be a desktop widget, it's being used
on the mobile version because of a lack of QML plotting library that
is fast and reliable.
We discovered that it was faster just to encapsulate our Profile in
a QML class and call it directly.
