The old code was leaking memory. Use std::unique_ptr<> for
ownership management.
This is still very primitive and divetags are kept during
application lifetime. There should probably be some form
of reference counting. And the taglist should not be global,
but attached to the divelog.

Mostly irrelevant std::move() stuff of copy-on-write Qt objects,

Unfortunately Coverity doesn't understand that most Qt data
structures are copy-on-write. It's a mis-feature of Qt, but
it is the way it is. Thus, passing by value is not an issue.
Out of ca. 25 warnings only two were legit. Let's silence
the others by either std::move()ing or passing by reference,
as would be idiomatic C++, which Qt is not.

The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.
Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).
The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.
To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.
The whole commit is large, but was mostly an automatic
conversion.
One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

In general, replace "dive master" by "dive guide".
However, do not change written dive logs for now. On reading,
accept both versions.

We have a dive-site variable, therefore we probably should also
have a dive-trip variable.

'constexpr' implies 'const' since it is a stronger guarantee,

And while doing that, have all the cases where we already include
qthelper.h simply use a define in that header file - but keep the two
other instances of the define where the C++ source don't need qthelper.h
otherwise.

Air is a special gas that does not contain oxygen according
to gasmix.o2.fraction. If you want to use the fo2, you
need to use get_o2() to treat this special case correctly.
This fixes a bug when setting the MND of a gas containing
21% oxygen when o2 is considered not narcotic.

To make box-and-whiskers charts selectable (select corresponding
dives when clicking on box), save the dive list with the quartile
data.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
If we want to make bar charts selectable (when clicking on a
bar select the dives the bar represents), then we must store
the dives behind bars. Therefore, use dive-based bins instead
of count based bins in bar charts and pie charts. This gave
some churn because every structure where a count is stored
has to be changed to store a vector of dives. Try to use
move semantics where possible to avoid duplication of dive
lists.
On a positive note, the count_dives() function of the
binners can now be removed, since it is unused.

The people binner (called "buddies") is too coarse. Split into

When calculating the quartiles, we need the count of dives
anyway, which makes it trivial to export this value to
the frontend.
Fixes an erroneous "mean", which should be "median".

This was requested on the mailing list and it makes sense to
have it. Of course, not all charts make sense: e.g. a plot dive-#
vs. count is a bit redundant...
Sadly, this can't use the generic IntRangeBinner, because dive-#s
start at 1, not 0.

The StatisticVariable class hierarchy encapsulates the concept
of a dive-variable, which can be plotted in charts either as
dependend or independend variable.
There are three types of these variables:
1) discrete: For example dive buddies or suit type.
2) continuous: Has a notion of linear metric - can be
used as histogram or scatter plot axis.
3) numeric: Like continuous, but allows for operations
such as calculating the mean or the sum over numerous
dives.
All variables support binning. The bins are defined per
variable.
Continuous variables can be converted into an arbitrary
double value, which is used to be plotted on a continuous
axis.
Moreover, numeric variables support a number of operations,
which depend on the variable.
Since binning is based on different types, the code is rather
template-heavy. Of course, this could be solved with
unions/variants and runtime-polymorphism, but using templates
was just much quicker. Notably, this uses the CRTP
(curiously recurring template pattern) where a subclass
passes itself as argument to the baseclass. This is a weird
kind of "reverse inheritance".
The StatsTranslations class is a dummy class which will
be used to collect all translations of the statistics
module.
This includes changes by Dirk to fix compilation of the
downloader.
