Improve transform tree coding.
...
- Clean up code and comment.
- Change terminology to match H.265 specification where possible.
- Move transform splitting for depth==0 out of the coding part. It's not
possible to do it here anyway because intra reconstruction is different
if the transform is split.
- Add checking for transform hierarchy depth when coding split flag.
- Fixes bug with cu_data.tr_depth being set. The CU struct was being reused
for inter coded CUs, which did not initialize the tr_depth.

Try to implement 4x4 luma transform coding.
...
- Doesn't work yet so it's disabled.
- Change encode_transform_coeff to accept PU (Prediction Unit) coordinates
instead of CU coordinates because CUs are 8x8.

Add new module sao.
...
- Move sao-stuff not directly related to encoding to sao-module.
- Calculate sao for all LCUs before encoding any of them. This is in
preparation to doing the reconstruction line at a time instead of
LCU at a time.

Merge branch 'master' into sao
...
SAO needs to be coded before LCU data has been searched. Searching
has already been moved to happen before encoding in the master branch.

Fix inter reconstruction for 8x8 blocks and enable 8x8 inter blocks again.
...
Inter reconstruction was modifying the movement in place when it shouldn't
have. This was causing issues only for the 8x8 blocks, because for larger
blocks the modified movement vector was too far away to be seen by the blocks
below it.
