Make the variable reduction_fac log2 based and explicitly use
right shift when computing intra_cost_penalty.

Use left shift to replace one multiplication. The computation
outcome remains identical.

Fails to compile. Bad calls to vp9_alloc_frame_buffer
and vp9_realloc_frame_buffer in postproc.c

This reverts commit 399823b6.

* changes:
  vp9: make postproc members depend on CONFIG_VP9_POSTPROC
  vp9_postproc: remove redundant CONFIG_* checks

Allows override of default target list. Also added missing usage info
for --extra-configure-args, and removed last vestiges of armv6 support.

Add support for setting byte alignment on the Y, U, and V plane of the
reference buffers. The byte alignment must be a power of 2, from 32 to
1024. A value of 0 sets legacy alignment.

The other name was misleading: We do not export scaling support from
libvpx via vpx_im{g,age}*.

This CL showed a modest gain in performance on some systems.

INLINE is used quite widely in vp9, this change improves performance
1-2% on most modern platforms.

the entire module is wrapped in CONFIG_VP9_POSTPROC which is forcibly
enabled with CONFIG_INTERNAL_STATS

set LIBVPX_RAND with --enable-vp9-postproc, previously only the vp8
config was checked. this fixes the build with --disable-postproc.

Assembly tests should clear system state, as we have no
expectation of proper system state in between test runs..

This is meant as a framework for testing that encode parms make it
through to the decoder.

This commit fixes a bug in the PICK_MODE_CONTEXT index for
horizontal partition case. The compression performance change
is less than 0.01% level, since most blocks are selected to
use square block size in RTC coding mode.

For key frame under variance source partition: 4x4 prediction blocks
may be selected when variance of 8x8 block is very high (threshold is set fairly high for now).

Testing on some RTC clips shows this helps to reduce some ringing artifacts on key frame.
Encoded key frame size increases about ~10%. Key frame PSNR increases about ~0.1-0.2dB.
