The concrete need on this change is to support passing an initial seed to the murmur hash. Passing a custom seed is important in terms of randomizing the hash function. The suggested implementation adds a HashTable parameter to all the init callbacks. Further on, an array with custom arguments is accepted from `hash` or `hash_init` from the user land. Currently several things like `hash_hkdf` are not touched, as they don't need passing custom args. Some convenience macros have been added to the SHA/MD families of functions, so the consuming code doesn't have to be changed widely. Another way to implement this is to add another type of the init that would accept a HT with arguments. However, that would still require touching all the context structs in all the algos. That would also increase the size of those structs. As an init function is called just once, the way of modifying the existing init callback has been seen as more preferrable. Closes GH-6400.
