When early termination is triggered, properly reset the rate cost
to invalid value to avoid potential ioc issue.

Covers all profiles and input formats. The tests check if the
encode succeeds and if the psnr is sane.

This commit fixes an ioc issue that will happen when the cumulative
variables are not in effective use. The fix discards these
redundant additions.

This removes an unnecessary restriction that causes
a problem (noticed by AWG) when the forced key frame
interval is set to a very small value, such as 10. In this case
we were being forced to code minimal length GF groups.

We encode a empty invisible frame in front of the base layer frame to
avoid using prev_mi. Since there's a restriction for reference frame
scaling factor, we have to make it smaller and smaller gradually until
its size is 16x16.

Change remerged.

This reverts commit 452dc215.

This change has introduced a significant quality regression on content
with forced key frames. (e.g. the YT and yt-hd set). It is most
noticeable in static content where the kf bits dominate. Here, despite
key frames being apparently coded at the same Q, there is a drop in all
metrics of ~20% (e.g clXR and BFa0).

Reduce the intra_cost_penalty for non-rd mode,
and some updates to VAR_BASED_PARTITION.

Visual tests show some improvement at Speed 6, for RTC clips.

This commit replaces the use of copy_partitioning with
choose_partitioning based on the sse of subsamped pixels, which
provides significantly better coding performance and runs at
similar speed, as compared to copy_partitioning. It improves rtc
speed 5 coding performance by 3%.

Fixes a bug introduced in a previous refactoring patch.

Change-Id: I243e74637cfd7a997c7a1fef03b06c290dd0dee6

this change checks that CONFIG_SPATIAL_SVC is defined and adds a TODO to
ensure this is changed in the future as the release headers can't
depend on vpx_config.h.
