OS/400 crypto library is unable to sign a precomputed SHA1 hash: however it does support a procedure that hashes data fragments and rsa signs. If defined, the new macro _libssh2_rsa_sha1_signv() implements this function and disables use of _libssh2_rsa_sha1_sign(). The function described above requires that the struct iovec unused slacks are cleared: for this reason, macro libssh2_prepare_iovec() has been introduced. It should be defined as empty for crypto backends that are not sensitive to struct iovec unused slack values.
