The data processed by the loopfilter overlaps. At the block level, this
results in some redundant transforms. Grouping the filtering allows for
a single 16x16 transpose (and inversion) instead of three 16x8 transposes
(and three more inversions).

This implementation is x86_64 only. We retain the previous
implementation for x86.

Improvements are obviously material dependant, but it seems to be ~%1 in
tests here.

vp8_find_near_mvs() is being called on all possible reference frames
but the data computed may be used if the loop exits early, which can
be due to x->skip beign set to 1.

Optimize this by call vp8_find_near_mvs() laziy only if it is going
to be used and not computed yet.

Changes to the selection of Q limits for two pass
and two pass CQ mode.

Allowance made for Mode and motion vector costs.
Some refactoring of common code.

For Derf and YT sets CQ mode average improvement
circa 1% (SSIM and Global PSNR).

Some increased tendency to undershoot even when
user CQ not reached.

Patch2: Removed some test code accidentally merged.

'all' is the conventional target for building everything in the
makefile, but the child make was expecting all-$(target), for debugging
reasons that I don't recall exactly. Restore the expected behavior.

* changes:
  vpxenc: get version string programatically
  Install missing default_coef_probs.h

To avoid a dependency on vpx_version.h, call the vpx_codec_version_str()
function and build up the string manually.

These files don't contain generic arm code, so should
only be compiled by neon.

Change-Id: Ie712823aa04d4235e7cfe7a3b725e73ee4c3e564

- Removed fast_fdct4x4_neon and fast_fdct8x4_neon
- Uses now short_fdct4x4 and short_fdct8x4
- Gives ~1-2% speed-up on Cortex-A8/A9

Rd and Rm registers should be different in 'mul'. This register
combination results in unpredictable behaviour. GCC will give
a warning and RVCT an error in this case.

Restriction applies only to armv5 targets and not for armv6 and above.

These changes fixes a glitch between the RTP profile and the input
partitions interface. Since there's no way for the user to know the
actual number of partitions, the decoder have to read the
multi_token_paritition bits also when input partitions mode is
enabled.

Included are also a couple of fixes for issues with independent
partitions and uninitialized memory reads.

- Updated walsh transform to match C
  (based on Change Id24f3392)
- Changed fast_fdct4x4 and 8x4 to short_fdct4x4 and 8x4
  correspondingly

according to comments. Scheduled code a little bit to prevent some
interlocks.

In the "Removed bmi copy to/from BLOCKD" commit, the copy
to the bmi in BLOCKD was eliminated.  The clamp_mvs() used
the bmi in BLOCKD, which now contains incorrect values.  This
patch fixes this problem.

for SPLITMV and B_PRED modes.  Modified code to use the bmi
found in mode_info_context instead of BLOCKD.  On the decode
side, the uvmvs are calculated only when required, instead of
every macroblock.  This is WIP. (bmi should eventually be
removed from BLOCKD)
Small performance gains noticed for RT encodes and decodes.(VGA)
