This allows us to use non-C member variables. Convert a number
of pointers to unique_ptr<>s.
Code in uemis-downloader.cpp had to be refactored, because
it mixed owning and non-owning pointers. Mad.

Some compilers whine when using typedefs with non-C structs with
default initializers. Not yet the case here, but in the future
probably will. So remove them now. No point in C++ anyway.

They make no sense under C++ and seem to produce tons of warnings

Wuth C++ the distinction between "typedef" and regular "struct"
makes no sense anymore. Remove the typedefs, it's just confusing.

Since everything is C++ now, we can use unique_ptr<>s. This makes
the code significantly shorter, because we can now use the default
move constructor and assignment operators.
This has a semantic change when std::move()-ing the divelog:
now not the contents of the tables are moved, but the pointers.
That is, the moved-from object now has no more tables and
must not be used anymore. This made it necessary to replace
std::move()s by std::swap()s. In that regard, the old code was
in principle broken: it used moved-from objects, which may work
but usually doesn't.
This commit adds a myriad of .get() function calls where the code
expects a C-style pointer. The plan is to remove virtually all of
them, when we move free-standing functions into the class it acts
on. Or, replace C-style pointers by references where we don't support
NULL.

There were only two of them, from the time C-code had to access
the divelog: clear_divelog() and delete_single_dive().
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The old code would construct and then initialize the object
in a separate function, which added lots of complication.
Just initialize the thing in the constructor, store a
reference, not a pointer to the table. And do a few other
code cleanups. The result is distinctly more pleasing.

There were a number of free standing functions acting on a
dive-site-table. Make them member functions. This allows
for shorter names. Use the get_idx() function of the base
class, which returns a size_t instead of an int (since that
is what the standard, somewhat unfortunately, uses).

This makes memory management more simple, as not explicit deletion
is necessary.
A rather large commit, because changing QVector<> to std::vector<>
is propagated up the call chain.
Adds a new range_contains() helper function for collection
types such as std::vector<>. I didn't want to call it
contains(), since we already have a contains function
for strings and let's keep argument overloading simple.

This is a long commit, because it introduces a new abstraction:
a general std::vector<> of std::unique_ptrs<>.
Moreover, it replaces a number of pointers by C++ references,
when the callee does not suppoert null objects.
This simplifies memory management and makes ownership more
explicit. It is a proof-of-concept and a test-bed for
the other core data structrures.

Makes the code much nicer to read.
Default initialize cylinder_t to the empty cylinder.
This produces lots of warnings, because most structure are now
not PODs anymore and shouldn't be erased using memset().
These memset()s will be removed one-by-one and replaced by
proper constructors.
The whole ordeal made it necessary to add a constructor to
struct event. To simplify things the whole optimization of
the variable-size event names was removed. In upcoming commits
this will be replaced by std::string anyway.

To my understanding, declaring empty parameter lists using "(void)"
is an artifact from the bad old K&R times, when functions were
declared without(!) parameters. Which in hindsight was an absolute
recipe for disaster. So for backwards compatibility, functions
without parameters had to be declared using "(void)" as "()"
could also mean "any function".
That was 40 years ago. Meanwhile, C++ introduced references,
which made it a necessity to declare the function parameters.
So "(void)" is redundant and inconsistent in C++ code and
just makes no sense.
Remove it.

The divesite-helper.cpp only existed because C-string manipulation
was too tedious. Now that divesite.cpp is C++ anyway, the split

Since this is now in C++, we don't have to use our crazy
TABLE_* macros.
This contains a logic change: the dives associated to a
dive site are now unsorted.
The old code was subtly buggy: dives were added in a sorted
manner, but when the dive was edited the list was not
resorted. Very unlikely that this leads to a serious
problem, still not good.

Use more C++ style memory management for plot_info: Use std::vector
for array data. Return the plot_info instead of filling an output

The bulk of the commit is replacement of pointers with references,
which is kind of gratuitous. But I started and then went on...

Convert both files simultanously, because the SI_UNITS define works
either under C or under C++.
This was painful, because initialization of struct-members has to
be done in order of definition in C++. And it was completely out
of order. However, as long as not all is C++, we can't use
default initialization directly in the struct definition. :(

The old code was wild: For the yearly statistics it would allocate
one entry per dive in the log. Of course, it would also leak
C-style strings.
Convert the whole thing to somewhat idiomatic C++.
Somewhat wasted work, because I'd like to convert the whole thing
to the new statistics code. But let's finish the conversion to C++
