Clean up trskip decision code and remove old code.
...
- You can define structs inside functions! This changes everything!!
- Bitstream changes a little bit compared to old trskip decision. Bdrate
change is insignificant though.

Remove abs_sum from coeff quantization.
...
- It's meant for checking if there are any coefficients, but we don't use it
and it's annoying to remember to initialize it and pass it around. The
benefit should be quite small anyway.

Add TR_MAX_WIDTH.
...
- Max transform size is constrained by but independent of LCU size.
- Luma and chroma now have the same stride for transform arrays.

Remove redundant variables.
...
- Redefine LCU_WIDTH to be 64. Stuff will break horribly if it's
anything else anyway.
- Add LCU_WIDTH_C for chroma LCU width. It should be more readable than the
constant (LCU_WIDTH >> 1).

Handle coefficient initialization better.
...
- Coefficients are no longer required to be pre-zeroed. The resulting zeroes
are copied in even in the case where we already know they are all zeroes.
- Move cbf clearing code to only happen at the leaves of the recursion.
