When temporal layers are used, only allow for copy partition
on the top temporal enhancement layer frames.

Only affects speed 8.

Make changes to copy partition to fix a bug in setting microblock
offset. Avg PSNR shows 0.02% gain on rtc_derf and 0.08% loss on rtc.

Add another (lower) bitrate to the test, to cover
frame drop behavior at low bitrate range.

Most existing first pass stats are stored in a form normalized to a
macro-block scale. However the error scores for intra / inter etc were
stored as frame level values but mainly used as MB level values.

This change  fixes that. Normalized per MB values make comparisons
between different formats easier and in any case this is usually what is
wanted.

An change in results should be limited to slight differences in rounding.

*** Change after patch 8 +2 requiring new approval.

Final pre-submit testing showed  one 4K clip with above expected change.
Investigation showed this was due to a value used to test for ultra low intra
complexity in key frame detection. This was a per frame not per MB value but
also did not scale with frame size. Replacement with a small per MB value
(based on original per frame value and cif frame size) resolved the KF detection
problem.

Also converted kf_group_error_left to a double in line with other error values
to reduce rounding problems in KF group bit allocation

All clips and sets now show nominal (or 0) change as expected.

Reason for revert: chromium builds are failing to locate vpx_rv during dlopen()

dlopen failed: cannot locate symbol "vpx_rv" referenced by "libstandalonelibwebviewchromium.so"

Mac builds must not specify 'protected' visibility. Then only support
'default' and 'hidden'.

During aosp builds with binutils-2.27, we're seeing linker error
messages of this form:
libvpx.a(subpixel_mmx.o): relocation R_386_GOTOFF against preemptible
symbol vp8_bilinear_filters_x86_8 cannot be used when making a shared
object

subpixel_mmx.o is assembled from "vp8/common/x86/subpixel_mmx.asm".
Other messages refer to symbol references from deblock_sse2.o and
subpixel_sse2.o, also assembled from asm files.

This change marks such symbols as having "protected" visibility. This
satisfies the linker as the symbols are not preemptible from outside
the shared library now, which I think is the original intent anyway.

Increase the partition and acskip thresholds for temporal
enhancement layers.

~1-2% speedup, with negligible loss in quality.

For SVC 1 pass non-rd pickmode, the interpolation filter for the
upsampling of the golden (spatial) reference was not being explicitly
set and instead was takin gwhatever value was set in the previous
mode/block (which would be either EIGHTTAP or EIGHTAP_SMOOTH).

Fix it to the default EIGHTTAP for now, to be updated/selected
adaptively in a later change.

Minor adjustmemt to rate targeting thresholds in datarate unittests.
