2698ca00e8 internal/pipewire: implement Core::Done
The message in the sample does not correspond to any known method call. The spec does not mention what to do with messages like this, but all existing usage code simply drops it.

1d0143386d internal/pipewire: optional final trailing garbage check
Omitting the check is only useful for custom unmarshaler.

a55c209099 internal/pipewire: additional Client::Info test case
This appears to add *one single entry* compared to the message before it. The inefficiency of this protocol is beyond imagination.

This message follows the other Client::Info event before it. No idea why.

14e33f17e5 internal/pipewire: check nil marshaler
NULL values have special case in the format. This check ensures correctness serialising nil pointers.

05391da556 internal/pipewire: implement footer
The POD itself is serialised without requiring a special case, however its presence is only indicated by the difference in size recorded in the header and payload.

a0eb010aab internal/pipewire: spa_dict trailing garbage within POD
This performs the check within the bounds of the POD only. This was not caught since spa_dict was only used as the final struct field until now.

Once again, already entirely supported, the offset is not yet fully verified but makes intuitive sense. Will verify this on future occurrences of the message.
