Core: let count_divecomputers() operate on an arbitrary dive

Browse source 
Currently, count_divecomputers only works on the current_dive.
Instead, let it take a pointer to an arbitrary dive. This is
in preparation for being smarter in the undo code concerning
which dive computer to show on deletion.
