+ get rid of __ops_malloc_passphrase() - strdup() works just as well + generalise __ops_seckey_forget() to become __ops_forget(), give it a size parameter, and make it work on things other than secret keys (passphrases for instance) + minor struct field enum renaming + minor function call renaming + add ops_io_t struct to hold pointers to IO streams, and pass it down where necessary
