  Log Message:
  -----------
  [scudo] secondary allocator cache optimal-fit retrieval

changed cache retrieve algorithm to an "optimal-fit" which immediate
returns blocks that are less than 110% of the requested size. This
reduces memory waste while still allowing for an early return without
traversing the entire array of cached blocks
