hash: move SHA1 implementations to its own hashing context Create a separate `git_hash_sha1_ctx` structure that is specific to the SHA1 implementation and move all SHA1 functions over to use that one instead of the generic `git_hash_ctx`. The `git_hash_ctx` for now simply has a union containing this single SHA1 implementation, only, without any mechanism to distinguish between different algortihms.
