Fix per_cylinder_mean_depth calculation for CCR

Browse source 
This patch is bigger than necessary because I also renamed the
get_cylinder_use() function to the much more accurate
get_cylinder_idx_by_use().

If we have no gas changes (except for a possible explicit first gas),
(which in the CCR case also means no bailout), this code will give you
correct per cylinder depth and duration for oxygen and diluent and
therefore create more reasonable gas consumption data for CCR dives.
