Define new hash-size constants for allocating memory
Since we will want to transition to a new hash at some point in the
future, and that hash may be larger in size than 160 bits, introduce two
constants that can be used for allocating a sufficient amount of memory.
They can be increased to reflect the largest supported hash size.
