Add special handling for bottom right LCU pixel.
...
I didn't take into account that the reference pixel on the top-left of the
LCU gets over written if we just replace the top reference pixels for
current LCU with the bottom reference pixels after doing the search.
To handle this I copy the pixel that gets overwritten to the vertical
reference pixels.

Add new reference pixel buffer management to encoding loop.
...
- 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.

Remove old unnecessary functions from search module.
...
- As we move to per-LCU encoding only search_lcu will be necessary.
- Function search_best_mode is no longer used.

Try and get NxN to work again.
...
- Moved NxN search to be done on the same level as other searches, as it's
really not any different from 2Nx2N.
- Produces working bitstream but reconstruction is different.
