crypto/hash: Have hashing functions take void * buffer argument

Browse Source 
Cryptographic hash function can operate on any area of memory,
regardless of the content their represent. Do not restrict to
array of char, use the void* type, which is also the type of
the underlying iovec::iov_base field.
