This had to be done simultaneously, because the table macros
do not work properly with C++ objects.

Since struct divecomputer is now fully C++ (i.e. cleans up
after itself), we can simply turn the list of divecomputers
into an std::vector<>. This makes the code quite a bit simpler,
because the first divecomputer was actually a subobject.
Yes, this makes the common case of a single divecomputer a
little bit less efficient, but it really shouldn't matter.
If it does, we can still write a special std::vector<>-
like container that keeps the first element inline.
This change makes pointers-to-divecomputers not stable.
So always access the divecomputer via its index. As
far as I can tell, most of the code already does this.

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.

This gives the distance between to location_t objects. It is
unclear why this was in divesite.cpp.
Moreover pass by value, not raw pointer.

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 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.

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.

The strtod_flags() function allowed for fine control of how to
parse strings. However, only two different modes were actually
used: ascii mode ("C" locale) and permissive mode (accept ","
and "." as decimal separator).
The former had already its own function name (ascii_strtod).
Make the latter a separatge function as well (permissive_strtod)
and remove all the flags rigmarole.

Owing to bitrot, this union only contained a float and therefore
is pointless. Let's remove it.
That makes the function name "integer_or_float()" non-sensical.
Call it "parse_float()" instead.
Moreover, change the output-arguments of "parse_float()" from
pointers to references, as null-pointers are not supported.
Finally, remove the "errno" check after "ascii_strtod()". As far as
I can tell, errno is not set in "ascii_strtod()" and using a global
variable for error-reporting it is an incredibly silly interface
anyway.

Had to rewrite the thing, because gcc's warnings don't work
with templatized var-args. Since there is no string-format.cpp
and I didn't want to inline it, moved it to format.cpp.
String formatting is distributed around at least four
headers: membuffer.h, subsurface-string.h, format.h
and format-string.h. This really should be unified!

Create a format_string_std function that works like format_string,
but does return a std::string instead of a strdup()ed C string.
Make it a global function to be used in other parts of the code.

This was very annoying, because the old code was not const-clean
at all and trampled all over buffers. This makes the new code
pretty messy for now.
