	Defines MD5 handler using EVP interface (e.g. using OpenSSL)

	int md5_handler(struct soap *soap, void **context, enum md5_action action, char *buf, size_t len)
	context can be set and passed to subsequent calls. Parameters:
	action =
	MD5_INIT:	init context
	MD5_UPDATE:	update context with data from buf with size len
	MD5_FINAL:	fill buf with 16 bytes MD5 hash value
	MD5_DELETE:	delete context
	buf		input data, output MD5 128 bit hash value
	len		length of input data
