5e7861bb00 internal/pipewire: handle dangling files in roundtrip
This should not be handled on every receive as it could cause valid (though impossible in current upstream implementation) messages to be rejected and raise a protocol error.

7cb3308a53 internal/pipewire: store proxy errors in context
This change fixes handling of non-fatal errors during a roundtrip as there can be multiple receive calls per roundtrip.

2b22efcdf1 internal/pipewire: rename context consume method
This name is more correct since it does not roundtrip, but receives messages. This is also more consistent with the method on event proxies.
