Showing the cursor while running (especially on terminals where it
blinks) is a bit visually distracting, and doesn't serve much purpose;
make it invisible in init_ui() and restore the original state in
exit_ui().
Keeping a sorted multi-set allows faster search by source /
source+destination address.
Fixes O(n^2) complexity when handling a lot of connections (now it's
O(n log n)).
Now, the user can decide to show only the program name, instead of the
full program path. It is useful, when you have a very long hierarchy of
directories, which, with the full path name, the user might not see the
program name.
When compiling with [-Werror=format-security] in Debian packaging occurs this error:
```
cui.cpp: In function ‘void show_ncurses(Line**, int)’:
cui.cpp:377:73: error: format not a string literal and no format arguments [-Werror=format-security]
377 | mvprintw(3 + 1 + i, cols - COLUMN_WIDTH_UNIT, desc_view_mode[viewMode]);
| ^
cui.cpp:379:29: warning: zero-length gnu_printf format string [-Wformat-zero-length]
379 | mvprintw(totalrow + 1, 0, "");
| ^~
```
This patch solve the problem.
