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. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
