Also remove the UNUSED() macro, as there were no users left.
The macro was silly anyway - there were many falso positives.

We can now return mutable/imutable depending on const-ness of
the parameter, owing to parameter overloading.

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
is not necessary anymore.
Moreover, return an std::string, since this is a core-function.

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.

Since the taxonomy is now a real C++ struct with constructor
and destructor, dive_site has to be converted to C++ as well.
A bit hairy for now, but will ultimately be distinctly simpler.

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...
Default initializiation of gas_pressures made it necessary to convert
gas.c to c++, though with minimal changes to the code.

These can all just be local objects.
Also, don't overwrite them with 0. We later want to convert the

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++
first.

This was the umpteenth inefficient reinvention of a trivial

as well use a balanced binary tree or a sorted array. In the

uemis_get_divenr() returns maxdiveid and passes mindiveid as a
global variable.
Make this more reasonable by returning a min, max pair.
The way mindiveid is an unsigned int and then reinterpreted as
int is very sketchy. This commit attempts to not change that
behavior.

uemis_get_answer() would put the raw response into a global variable.
This could be anywhere in the call stack and thus you never knew
when the existing buffer was removed under your feet.
Instead, return the buffer explicitly from uemis_get_answer().
I'm nit perfectly happy about the new interface: an error is
indicated by an empty buffer, which is awkward to test for.
If an empty buffer turns out to be a valid response, this
should be replaced by an std::optional<> or std::expected<>.

The string code of uemis-downloader.cpp was broken in more ways
than can be listed here. Notably, it brazenly refused to free any
memory allocated for the parameters buffer.
Using std::string and std::string_view should plug all those
memory holes. That made it necessary to do some major refactoring.
This was done blind and therefore will break.

newmax was an integer variable kept as a string. Very ominous.
Moreover, memory management seems to be broken:
1) The string is never freed.
2) The string is passed as value from do_uemis_import() to
get_matching_dives(), which passes it as reference to
process_raw_buffer(), which may reallocate it, which means
that do_uemis_import() now possesses a pointer to a free()d
string.
Simplify all that by making newmax an integer variable and
passing it as a reference from do_uemis_import() to
get_matching_dives().

There were a number of fprintf()s that escaped the conversion
to report_info(), because they used "debugfile" instead of
"stderr" as target. However, debugfile was just #defined to
be stderr, so we might just use report_info() for consistency.

The uemis code is wild. It simply doesn't deallocate memory
and uses global variables. To get this under control, create
a "struct uemis" and make the functions exported by "uemis.h"
members of "struct uemis". Thus, we don't have to carry around
a parameter for the state of the importing process.
Turn a linked list of "helper" structures (one per imported dive)
into a std::unordered_map, to fix leaking of the helper structures.
