Add varargs function: secret_schema_new vs. secret_schema_newv

* Rename secret_schema_new to secret_schema_newv which
   accepts a GHashTable
 * Make secret_schema_new accept varargs similar to the
   password functions.
 * This is useful from vala which supports varargs

+ * Each schema has an @name like "org.gnome.keyring.NetworkPassword", and

+ *
+ * The variable argument list should contain pairs of a) The attribute name as

+ * each attribute name. The list of attribtues should be terminated with a %NULL.

+ * Normally when looking up passwords only those with matching schema names are
