pod: improve the vararg pod builder and parser
Automatically parse and build key/value when in objects without having to prefix the key with ":" Automatically build control/value when in sequence without the "." prefix. Remove the builder with key/pod, taking a reference to the stack built temporary pods is not allowed in c++. We can use the varargs version with the same convenient syntax. Remove the parser "*" option, it is unused. Improve spa_pod_builder_add_* and spa_pod_parser_get_* and make them look similar.
