dc32f7f0a3 Reduce allocations in HashFile 
By using copyBuffer we avoid a buffer allocation for each block we hash,
and by allocating space for the hashes up front we get one large backing
array instead of a small one for each block. For a 17 MiB file this
makes quite a difference in the amount of memory allocated:

	benchmark               old ns/op     new ns/op     delta
	BenchmarkHashFile-8     102045110     100459158     -1.55%

	benchmark               old allocs     new allocs     delta
	BenchmarkHashFile-8     415            144            -65.30%

	benchmark               old bytes     new bytes     delta
	BenchmarkHashFile-8     4504296       48104         -98.93%
