of 2D array. This used shift_y in setup_mask directly, and saved
few cycles.

Jingning Han 34b6abefa2 Enable dual buffer rd search and encoding scheme
This commit enables the dual buffer rate-distortion optimization
and encoding scheme. It stacks the original transform coefficients,
quantized levels, and reconstructed coefficients, in the rate-
distortion optimization search process, hence eliminates the need
to re-run residual generation, forward transform, and quantization
in the encoding stage.

Added loop filter mask checking, and made the caller function
ready for implementation of parallel loopfiltering in horizontal
direction.

Next, we need to go through the loopfilter functions (both c and
optimized versions), and provide 16-byte wide loopfiltering for
each filter type.

bsize < BLOCK_8X8 -- under that condition raster_block == block.

"xd->mb_to_right_edge < 0" and "xd->mb_to_right_edge < 0". If has_eob == 0
then memset does the right thing and works faster.

This patch continued the work done in "Rewrite loop_filter_info_n
struct"(commit:00dbd369c70270428d56da6d15ea5486fc821c52) to further
improve loopfilter function.

1. Instead of storing pointers to thresholds, store loopfilter
levels within 64x64 SB;
2. Since loopfilter levels are already calculated in setup_mask,
we don't need call build_lfi to look up them again. Just save
loopfilter levels in setup_mask.
3. Reorganized and simplified filter_block_plane().

Tests showed a ~0.8% decoder speedup.

Dmitry Kovalev 672ba3ddf5 Unifying tile decoding for both direct and inverse tile order.
Now tile decoding consists of two stages:
1. Find tile buffer start and its size, put this info into tile_buffers.
2. Decode each tile based on information from tile_buffers.

It seems that stage 1 can also be reused by multithreaded tile decoder.

Dmitry Kovalev a1dc97beb1 Using pd->dqcoeff instead of pd->qcoeff in the decoder.
It is more logical to use dqcoeff buffer to put there *dequantized*

decode_coefs functions). Dequantization happens inside WRITE_COEF_CONTINUE
macro.

qcoeff buffer should be only used in the encoder for *quantized*
transform coefficients.

- track individual frame sizes and psnrs instead of averages
- parameterized quantizer, 16th scalefactors, more logging,
- enabled single layer encodes to generate baseline
- include new mode for 3 layer I frame with 5 total layers

motion vectors of invalid value and check the mv_cost, which triggers
overheap read. This commit resolves this issue by forcing a motion
vector value check for compound inter modes of both superblock and
sub8x8 block sizes.

Dmitry Kovalev dde8069e57 Splitting partition_probs array into two arrays.
We only update partition_probs for inter frames but they are constant
for key frames. It is not necessary to have constants inside frame
context and copy them every time. This change reduces FRAME_CONTEXT size
by at least 48 bytes.

Dmitry Kovalev df19c6b64c Removing 'new' probability calculation from convert_distribution().
We don't have to calculate 'new' probability in convert_distribution()
because it is enough to calculate only 'new' counters which could be used
to calculate probability if necessary. That's why removing a lot of unused
temporary probability arrays and reducing number of get_binary_prob()
calls.

2. Removed a redundant level of indirection.

for tranforms other than DCT_DCT. In this case, the DCT_DCT case
has been already handled here.

Dmitry Kovalev 47b6030dda Reducing the number of foreach_transformed_block() calls.
The change doesn't affect the bitstream. It changes the order or function
calls and affects how we reconstruct intra- and inter-blocks. Speed up is
about 1...1.5%.

For intra-blocks:
  Before:
    for each transform block read tokens
    for each transform block do prediction
    for each transform block do inverse transform
  Now:
    for each transform block
      read tokens
      do prediction
      do inverse transform

For inter-blocks:
  Before:
    for each transform block read tokens
    for each transform block do inverse transform
  Now:
    for each transform block
      read tokens
      do inverse transform
