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.

We only used "ib" to call get_scan() function, which in turn calls

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().

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*

Move SVC per-frame loop from sample app into libvpx proper
SVC multiple layer per frame encoding is invoked with vpx_svc_init and

Additional improvements:
- make dummy frame handling a bit more explicit
- fixed bug with single layer encodes
- 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
