hash: add ability to distinguish algorithms Create an enum that allows us to distinguish between different hashing algorithms. This enum is embedded into each `git_hash_ctx` and will instruct the code to which hashing function the particular request shall be dispatched. As we do not yet have multiple hashing algorithms, we simply initialize the hash algorithm to always be SHA1. At a later point, we will have to extend the `git_hash_init_ctx` function to get as parameter which algorithm shall be used.
