hash: split into generic and SHA1-specific interface As a preparatory step to allow multiple hashing APIs to exist at the same time, split the hashing functions into one layer for generic hashing and one layer for SHA1-specific hashing. Right now, this is simply an additional indirection layer that doesn't yet serve any purpose. In the future, the generic API will be extended to allow for choosing which hash to use, though, by simply passing an enum to the hash context initialization function. This is necessary as a first step to be ready for Git's move to SHA256.
