Move picture-sse2.c to src/inline-optimizations/.
...
- Having it in the src dir even though it's not a module on it's own breaks
the scons build script. It's probably better to have these a little bit
separated from the normal code anyway.

Remove depth dimension from picture->cu_array.

- It was used in the past to hold information during search, but now that
information is held in lcu_t structs.

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.
