There exist some function to display the stats from each allocator
(show_<allocator>_alloc()) but these functions need to be
called one by one and deosn't allow to make some totals.
Chnage this by adding show_allocation_stats() which display
(in a more consise way) the stats from every allocator, together
with the totals.
