The `Modules/hashlib.h` helper file is now removed and split into multiple files: * `Modules/_hashlib/hashlib_buffer.[ch]` -- Utilities for getting a buffer view and handling buffer inputs. * `Modules/_hashlib/hashlib_fetch.h` -- Utilities used when fetching a message digest from a digest-like identifier. Currently, this file only contains common error messages as the fetching API is not yet implemented. * `Modules/_hashlib/hashlib_mutex.h` -- Utilities for managing the lock on cryptographic hash objects.
