In PEM, we need to parse until error and then suppress PEM_R_NO_START_LINE, because PEM allows arbitrary leading and trailing data. DER, however, does not. Parsing until error and suppressing ASN1_R_HEADER_TOO_LONG doesn't quite work because that error also covers some cases that should be rejected. Instead, check BIO_eof early and stop the loop that way.
