We currently do a little too much work when we push the first buffer around
resulting in excessive caps checking. We can probably make this a little less
expensive.
- Remove the result format value in queries.
+- Try to minimize the amount of acceptcaps calls when pushing buffers around.
+ The element pushing the buffer usually negotiated already and decided on the
+ format.
+ The element receiving the buffer usually has to accept the caps anyway.
