Split some parts of encoder_control into encoder_state

Goal is to allow multiple substreams in the future.

Address clang-analyzer warnings about garbage values.
...
- False alarm, but surprisingly difficult to convince clang of that. It
doesn't seem to understand bit shifts very well.
- Only assert and changing LCU_WIDTH>>depth to width was necessary to satisfy
clang.
- Closes #35 .

Take intra mode based coeff scan mode into account for coeff bit cost.

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.
