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.

Allocate memory space of dual buffer sets that store the coeff, qcoeff,
dqcoeff, and eobs. Connect the pointers of macroblock_plane and
macroblockd_plane to the actual buffer in use accordingly.

Make the macroblockd_plane contain dynamic buffer pointers instead
static pointers to the memory space allocated therein. The decoder
uses the buffer allocated in pbi, while encoder will use a dual
buffer approach for rate-distortion optimization search.

This to make sure that prediction residue always get coded in lossless
mode.
This commit also fixed lossless unit test

This patch fixed the issue reported in "Issue 655: remove textrel's
from 32-bit vp9 encoder". The set of vp9_subpel_variance functions
that used x86inc.asm ABI didn't build correctly for 32bit PIC. The
fix was carefully done under the situation that there was not
enough registers.
After the change, we got
$ eu-findtextrel libvpx.so
eu-findtextrel: no text relocations reported in 'libvpx.so'

The term x represents macroblock pointer across encode_block. Change
the two local variable names to avoid confusion.

SVC multiple layer per frame encoding is invoked with vpx_svc_init and
vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
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

Removing special case handling from vp9_tree_probs_from_distribution(),
tree_merge_probs(), and vp9_tokens_from_tree_offset() functions. Replacing
inter_mode_offset() function with macro INTER_OFFSET which is used now for
vp9_inter_mode_tree definition.

The compound inter prediction could potentially run with initial
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.

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.

Removed:
goldfreq, avg_encode_time, avg_pick_mode_time,
cpu_freq, interquantizer
member variables from VP9_COMP since they are no longer
used in the code.

Removed three members from the VP9_COMP data structure:
inter_zz_count, gf_bad_count, gf_update_recommended.
These were part of the VP8 real-time mode implementation
that was removed from the initial VP9 codecbase.

This commit fixes the use case of plane_block_idx, which determines
the plane (Y/U/V) index based on block index. When block idx >= 4 in
sub8x8 block loop, it should be of chroma components.

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.

-Don't reduce maxQ for gold/alt in CBR mode.
-Fix to min/maxQ for first/initial key frame.
-Add more speeds to datarate test and reduce the starting bitrate for test.

This commit makes zcoeff_blk cache the case where the entire block
is quantized to be zero (without applying zero-forcing) in the rate-
distortion optimization loop, and skip the forward DCT, quantization,
inverse DCT, and reconstruction process in the encode_block stage.
It now works for all the block sizes, including sub8x8 blocks.

"<< SUBPEL_BITS" needs to be added in the calculation. Call
set_scaled_offsets() to calculate x_offset_q4 and y_offset_q4.
