Let's add a comment here and create bug later to study making these plain pointers RefPtr or similar.

After talking to Quique (Enrique) in person, we saw that there are cross references in place and we don't want to mess this up.

It seems to be assumed that m_client is non-null throughout the lifetime of SourceBufferPrivateGStreamer, at least how it's used in append() and because it's not nulled out anywhere.

If that's the case, the parameter to this constructor and the member variables should be Ref<>, and there's no need to null-check it anywhere.

These can be initialized in the constructor.

Default it.
