This should allow us to continue expanding later in the same way that 0.10 was

We need to express things with less fields. This would speed up caps, make
them less verbose and speed up some elements.
* Add GstFlowReturn for events (and query)
This would allow us to know more precisely what went wrong.

Typechecking of various types is much more efficient when there is only
one class.

We need to perform less caps operations when negotiating formats. One way is
to only handle small caps objects incrementally.
