Add a new features property to the metadata param. This should be of type CHOICE_FEATURES_Int and should contain the extra features supported by this metadata. Make a special features metadata type that is a combination of the metadata type in the upper 16 bits and the features for that type in the lower 16 bits. Make a function to search if a type has certain feature bits. On the server, when negotiating buffers and metadata, check the result of the features after filtering and if they are not 0, place them as 0 sized extra feature metadata on the buffer. Add some metadata features for the sync_timeline, one that specifies that the RELEASE flag is supported. With this in place, a producer can see if a consumer supports the UNSCHEDULED_RELEASE flag.
