Fix building of reference border in the bottom of the frame.
...
- Don't write to the top-left corner during construction of left border,
because that is handled later that is handled later.

Reimplement intra_build_reference_border to support NxN.
...
New implementation uses precalculated tables to look up number of reference
pixels available in coded CUs. Otherwise it works just like the previous
version.
- NxN mostly works. Prediction appears to be almost correct but there is a
slight error in the exact values, probably related to filtering.

Work on reconstruction and searching.
...
- Set part-size for Inter.
- Change to Intra Only mode for testing.
- Many small changes here and there. Should have been separate commits probably, but too late.
- Disable SAO and deblocking to be able to see problems with reconstruction better.

Try to fix intra prediction mode coding for NxN.
...
- Adjust predictor list to take modes from PUs in addition to 2Nx2N CUs.
- Change intra_get_dir_luma_predictor to take PU index instead of CU index.
- Comment prediction encoding now that I've had to look it up.

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.

Refactor intra sad calculation functions.
...
- Move SATD (hadamart) code to it's own functions.
- Generate functions for fixed block sizes with macros, as if using templates.
- Define new interface with function pointer cost_16bit_nxn_func that different
cost functions can use.
- Hide fixed size block cost functions with getters.

require stdint.h.
