transform skip vs. normal transform selection criteria might need more work, currently both are calculated for each 4x4 block and SAD+coeff_SSE is compared.
- This is necessary because after we add in-loop filters to be done per LCU,
the reconstruction buffer will have the deblocked pixels. We only need the
edge-pixels for intra prediction though so we just save those.
- Right now it only copies the pixels and passes them on to search, where
the copied pixels are asserted to be the same ones we copy from
reconstruction buffer.
- New yuv_t struct added for arrays of dynamic length. We might want to change
other buffers to use it or something like it in the future.
- Working towards issue #11.
- Widened datatypes for cfg struct members that take values from atoi to full
ints so that bounds checking can be done after parsing without overflow.

- Chroma RDOQ changes conflicted because I had moved the chroma
quantization/dequantization to it's own function.
- Merged to master because I want my code to show up in github. =)
All the old stuff still works, even though NxN doesn't work, so there
is no reason not to merge anyway.
- 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.
- Add room to cu_data.coeff_top_yuv arrays for the 4x4 PUs data. Will probably have to do the same to other coeff flags. The flags could also probably be combined as they are a bit redundant.
- 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.
SAO needs to be coded before LCU data has been searched. Searching
has already been moved to happen before encoding in the master branch.

- 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.
