Properly allocate/release memory when adding filters to the filtergraph. 

When connecting pin, discard filter which is the same as the upstream
one.
Remove wrong extra IBaseFilter_Release.
Improve traces by showing filters owing pins we want to connect or
render.
Properly initialize output pin of transform filter.
