Remove chroma mode "36".
...
- It's an unnecessary chore to handle this special case everywhere (it means
chroma_mode == intra_mode). Better just to use the actual mode.

which the modes are tried and when two modes have the same cost the first
one is chosen.

Fix compiler warnings for VS2010 /W4 in intra.c.

- Working towards issue #11 .
- Removed intra_get_block_mode as unused.
- Removed unused parameters from functions. Many of them were remnants from
earlier data structures and earlier features of HEVC that have been removed.
- Lots of implicit conversions from larger types to smaller ones. I tried to
avoid turning all of them to explicit ones this time and opted for changing
the original data type instead. Had to do it in few cases though to stop the
changes from propagating too widely.
