* Add memory pool support.

 - memory pools would be used in modules for allocating task specific data without freeing it separately
 - memory pools growth is implemented as multiplying by 2 its length (for avoiding multiply reallocs)
 - when memory pool is freed all data that was allocated from this pool is freed too
