9d2bd425e1 core: fix memory leak in tables code
The function clear_*_table frees all elements of the table.
However, persumably as a performance feature, it kept the
memory of the table itselt (i.e. it only reset the number of
elements but kept the capacity).

That is fine if the table is reused later. However, this
function was also used when freeing the table and this
would leak the table memory.

This commit frees the table memory. An alternative would
be to have separate clear_*_table and free_*_table functions.
But let's wait with that until we port the table code to C++.
Then this will be "automatically" fixed.

ebdb3e3c30 media: create sort_picture_table function via macro
This needs a slight change to the macro, because here we sort by
value type. Yes, from a C-programming point of view this is horrible,
however a decent compiler should just inline everything and not
pass around value types.

6e343c734a Core: implement move functions for dive and dive_site table
To allow efficient moving of downloaded dives from the download
thread to the model, implement a general move function that
moves table data. Instantiate that function for the dive and
dive_site tables.

a5e7f4253a Core: dynamically resize weight table
Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.

The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

3df32044ee Cleanup: generate clear_*_table() functions by macro
In analogy to the other table functions, generate these by
a macro as well.

59e602447b Dive site: inform model of dive site addition / deletion
Introduce two DiveListNotifier signals which are sent by
the undo commands if dives are added to / removed from the
core.

The signal has the dive site and the index in the global
dive site table as payload. Thus, the model has only to
remove the appropriate rows.

a6f65d744f Cleanup: move table-macros into own header
dive- and trip-table functions are generated in dive.c by macros.
Move this macros to a new "core/table.h" header file.

Thus, these functions can be used for other tables (e.g. dive site)
and the trip function can be moved to a separate translation unit
(divelist.c being quite large already).
