Fix tracing
Enc-dec matching tracing for D_HEADER,D_SYNTAX,D_SYNTAX_RESI,D_CABAC Tracing for several elements added
Noticed problems:
- Many elements are still untraced, but adding them will expand the log drastically. I am open to recommendations if something else is crucial to add.
- No common style to order pos, ctx, val (can be val, ctx, pos etc.)
- Several elements use unconditional tracing, others are traced only when explicitly coded
Several specific comments are added
