Add src_query() sink_query() virtual method

I am implementing a V4L2 based decoder which has dynamic capabilities. This mean, i need to implement caps query. I had the option to add a src_get_caps()/sink_get_caps() but thought this is a rare case, and it's simply more generic to have access to all queries, like we do for event.

Also added in the encoder for consistency. We should try to keep their APIs as similar as possible.
