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

It is more logical to use dqcoeff buffer to put there *dequantized*
transform coefficients (inside inverse_transform_block and
decode_coefs functions). Dequantization happens inside WRITE_COEF_CONTINUE
macro.
qcoeff buffer should be only used in the encoder for *quantized*
transform coefficients.

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

I'm sure I could do more, but I don't know how long this code has to
live. I think this at least makes the code a little easier to read and
understand.

This is mainly a clean up patchset. It moves the WebM writing support
out of vpxenc and into its own source file. Changes to tools_common and
vpxdec result from relocation of shared bits of code.

Removes stack-alocation of token_cache in decode_coefs function
Seems to achieve about 1% decode speed improvement as tested on
25 480p videos.

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.
Change-Id: I010a82c217d0da03c3f53d1858d3462190c12dcf
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.

When a frame is dropped due to |buffer_level| < 0 for a given temporal layer,
the buffer level for the upper temporal layers was not updated (in calc_pframe_target_size()).
This change fixes that.
Also, use the layer per-frame-bandwidth for updating the buffer level
of the higher layers when a frame is dropped.
