4d7291d4a1 core: move merge_dives() functios to struct dive_table
These functions have to access other dives in the list to
calculate CNS, etc, so let's call them from there.

176f544106 core: move process_import_dives() and related functions to divelog
These functions accessed the global divelog make this explicit.

I'm still not happy about the situation, because these functions
access global state, such as the selection. I think these
should be moved up the call-chain.

91968ac579 core: remove filterconstraint C boilerplate code
Since all code can now directly access C++ structures these
accessor functions were not necessary.

Split out the table from the filterconstraint source file
and include it directly into the divelog.

2bdcdab391 core: include trip table directly in divelog
Having this as a pointer is an artifact from the C/C++ split.
The triptable header is small enough so that we can
include it directly

b95ac3f79c core: turn C dive-table into an owning table
This is a humongous commit, because it touches all parts of the
code. It removes the last user of our horrible TABLE macros, which
simulate std::vector<> in a very clumsy way.

5c7cfb1057 core: replace list of dives in trip by std::vector<>
The dive_table will be converted into a table of owning pointers.
Since the trip has only non-owning pointers to dives, turn
its dive_table into an std::vector<dive *>.

Add a helper functions to add/remove items in a sorted list.
These could be used elsewhere.

eacad89531 core: turn trip-table into our own sorted_owning_table
Since the sorted_owning_table depends on the fact that
different elements never compare as equal, make the
comparison function safer in that respect. If all failes,
compare the pointers.

d242198c99 divelog: turn owning-pointers into unique_ptr<>s
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.

e39dea3d68 core: replace divesite_table_t by a vector of std::unique_ptr<>s
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.

e20ec9248c core: fix leak when clearing dive log
46cf2fc086 fixed a bug where clearing of a divelog, such as the one
used for import, would erase dives in the global(!) divelog.

However, the new code used the function clear_dive_table(), which
only cleared the table without unregistering the dives. In particular,
the dives were not removed from the trips, which means that the trips
were not free()d.

This reinstates the old code, but now passes a divelog paremeter
to delete_single_dive() instead of accessing the global divelog.
Moreover, delete dives from the back to avoid unnecessary
copying.

An alternative and definitely simpler solution might be to just
add a "clear_trip_table()" after "clear_dive_table()".

a8d2b2ff70 divelog: fix erroneous use of std::move()
This has to be applied to the object, not the pointer to the object.
Fixes a double-free crash introduced in 8cd451f.

Alternatively, we could use std::swap() for C++98 charm and perhaps
better readability for people unfamiliar with C++11. Nowadays,
std::move() is more idiomatic though. Shrug.

9c253ee6c5 core: introduce divelog structure
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.
