Use int64_t type for distortion. This avoids integer overflow
issues in the trellis optimization function in high bit-depth
settings.

Commit 0d6980d7 removed some use
of the skip_txfm optimization, and the rest are not productive.

The current use of this optimization is only used with --good
and --cpu-used >= 3, however the overhead of this is higher than the
speedup it yields.

Removing this, and subsequently simplifying model_rd_for_sb yields
a net encoder speedup:
--cpu-used=0    ~1.5% faster
--cpu-used=3    ~2.0% faster

The code simplification is also significant.

- Fix the over-writing bug in horizontal filtering as width = 2.
- Fix 10-tap vertical filtering which no longer reads one row of
  pixel above the block.
- Fix 10-tap filter zero padding.

Use the trellis optimization based uniform quantizer to encode the
sub8x8 block coding.

This commit refactors the transform and quantization process for
sub8x8 blocks and unifies the related functions.

Replace the expanded zero-bin quantizer with uniform quantizer in
the recursive transform block partitioning scheme. This improves
the compression performance by 0.4% for lowres.
