Clean up trskip decision code and remove old code.
...
- You can define structs inside functions! This changes everything!!
- Bitstream changes a little bit compared to old trskip decision. Bdrate
change is insignificant though.

Remove abs_sum from coeff quantization.
...
- It's meant for checking if there are any coefficients, but we don't use it
and it's annoying to remember to initialize it and pass it around. The
benefit should be quite small anyway.

...
- Redefine LCU_WIDTH to be 64. Stuff will break horribly if it's
anything else anyway.
- Add LCU_WIDTH_C for chroma LCU width. It should be more readable than the
constant (LCU_WIDTH >> 1).

are copied in even in the case where we already know they are all zeroes.

Clear old cbf data before recursion in encode_transform_tree.

- Because encode_transform_tree also maintains the CBF data and assumes that
the CBFs are initially zeroed, calling the function more than once would
result in incorrect CBF data.

Improve cu_info coded block flag data structure a bit.
...
- It works just like the old structure except that the flags are checked with
bitmasks instead of having the flag value be propagated upwards. There isn't
really any benefit to this because the flags still have to be propagated to
parent CUs.
- Wrapped them inside a struct to make copying them easier. (Just need to copy
the struct instead of making individual copies)

Pass preprocessor defines for supported intrinsics in VS2010 explicitly.
...
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
instructions. It isn't correct to use it to check whether optional runtime
optimizations should be compiled in. It's also not defined at all in 64-bit
mode.
- So let's just keep it simple and give a list of everything that is supported
as release optimizations. It's not clear from the documentation if all of
these are really supported. It just list a bunch of intrinsics from these
that are.

Modify deblocking to be done per-LCU in the encoding loop.
...
- Intra works. There is still something wrong in inter.
- Avoid horizontal deblocking of the rightmost 4 pixels in the LCU.
This is because vertical deblocking must be done for all pixels
before horizontal, but vertical deblocking can't be done for those
pixels before the next LCU is finished.
- Add separate deblocking of the rightmost pixels of the last LCU
after the LCU edge has been deblocked.
- This is a pretty ugly hack but will have to do for now.

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.

According to spec the end_of_slice_segment_flag is always coded, but in the
code it looked like it was not coded for the last LCU in picture. This was
due to the end_of_slice_segment_flag being coded inside cabac_flush, like it
is in HM. This is a bit silly so I moved it out of cabac_flush.
