This patch provides a partial rapid feedback of bits
resulting from extreme undershoot.
Some improvement on some problem animated material
but in its current form only a small impact on the metrics results
of our standard test sets.

This patch addresses two issues that can occur when the
encoder chooses to use a mixture of ARF and GF groups.
The first issue relates to a failure to reset the "ARF active" flag
correctly when transitioning from coding ARF groups to coding
GF groups. This caused some golden frames to be encoded
with an incorrect bit rate target as if they were ARF overlay frames.
The second issue relates to the encoding of a single short GF group
just before a key frame. Where the last group before a key frame
is an ARF group we expect the final frame before the key frame to
be an low data rate overlay frame. However, when the last group
is a GF group, the final frame before the key frame should be a normal
frame with a normal bit allocation. This issue had the potential to cause
a single poorly coded frame just before a key frame. If that key frame
were a forced key frame rather than a real scene cut, this might cause
pulsing.

This allows rate control to react to content of current frame being encoded.
Enabling this feature via the setting: screen_content_mode = 2.

this allows test_libvpx's simd caps check to be used; it also fixes a
link error on OS X with -fcommon.

in addition to <arch>/*. this will pick up tests defined with TEST()

* changes:
vp9_subexp.h: add a missing prototype
vp9: add some missing includes
vp9 intrinsics: add vp9_rtcd include
vp9: correct some function signatures
vp9_variance_sse2: sync function signatures

Use the same settting as in speed >=6.
This will use same logic for tx_size selecton as in speed >=6,
which limits the transform size and reduces ringing artifact.
Also metrics go up on average with this change: ~2% for PSNR, ~10% for SSIM.

Add a check to make sure we have a decoded frame available
before copying its 'corrupt' flag.

Testing on another rate control patch reveals that in some
situations, where the encoder is flipping in and out of arf
mode, we get an encoder decoder mismatch.
Whilst it is still not clear why, skipping the last buffer
update seems to trigger the problem. Until I can establish
why, or if there is another underlying cause, I am reverting
this change.
This reverts commit e5112b3ae3352c4c55fb31235305f3f80f4b8f7e.
