Shortcut arg for --extra-configure-args --enable-examples. Enables
the examples, and thus ensures that all versions of libvpx that
iosbuild.sh produces can actually be linked.

fixes build on windows x64; previously 'heightq' i.e., the 64-bit register
was accessed when only the 32-bit value was needed. given this is from a
stack variable the upper bits were undefined.
+ bump register/xmm counts; users of SETUP_LOCAL_VARS touch xmm13 in
64-bit builds and filter_block1d16_v* uses one extra temp variable

This commit removes mbmi_ext_base pointer from MACROBLOCK struct.
Its use case can be fully covered by cpi->mbmi_ext_base pointer.

Add SVC codec control to set the frame flags and buffer indices
for each spatial layer of the current (super)frame to be encoded.
This allows the application to set (and change on the fly) the
reference frame configuration for spatial layers.
Added an example layer pattern (spatial and temporal layers)
in vp9_spatial_svc_encoder for the bypass_mode using new control.

This means that we don't reconstruct in 4x4 dimensions, but in
blocksize dimensions, e.g. 4x8 or 8x4. This may in some cases lead
to performance improvements. Also, if we decide to re-introduce
scalable coding support, this would fix the fact that you need to
re-scale the MV halfway the block in sub8x8 non-4x4 blocks.
See issue 1013.

In vp9, the bottom MV would be the average of the topright and
bottomleft luma MV (instead of the bottomleft/bottomright luma MV).
See issue 993.

This has virtually no effect on coding efficiency, but it is more
logical from a theoretical perspective (since it makes no sense to
me that you would exclude a MV from a list just because it's sign-
inversed value is identical to a value already in a list), and it
also makes the code simpler (it removes a duplicate value check in
cases where signbias is equal between the two MVs being compared).
See issue 662.

For reading, this makes the operation branchless, although it still
requires two shifts. For writing, this makes the operation as fast
as writing an unsigned value, branchlessly. This is also how other
codecs typically code signed, non-arithcoded bitstream elements.
See issue 1039.

The implicitly changed value would be used for contextualizing future
skip flags of neighbour blocks (bottom/right), which is certainly not
what was intended. The original code stems from vp8, and was useful
in cases where coding of the skip flag was disabled. In vp9, the skip
flag is always coded. The result of this change is that for bitstream
parsing purposes, decoding of the skip flag becomes independent of
decoding of block coefficients.
See issue 1014.

In decoder, export (eventually) into vpx_image_t.range field. In
encoder, use oxcf->color_range to set it (same way as for
color_space).

Verify the dynamic resizer behavior for real time, 1 pass CBR mode.
Start at low target bitrate, raise the bitrate in the middle of the
clip, verify that scaling-up does occur after bitrate changed.

Verify the dynamic resizer behavior for real time, 1 pass CBR mode.
Run at low bitrate, with resize_allowed = 1, and verify that we get
one resize down event.

For 1 pass CBR spatial-SVC:
Add cyclic refresh parameters to the svc-layer context.
This allows cyclic refresh (aq-mode=3) to be applied to
the whole super-frame (all spatial layers).
This gives a performance improvement for spatial layer encoding.
Addd the aq_mode mode on/off setting as command line option.

Fixes temporal scalability. Updates were inadvertently turned
off for two pass svc causing crashes due to gf_group.index
growing unchecked.

The counts didn't take usehp into account, which means that if the
scope of the refmv is too large for the hp bit to be coded, the value
(always 1) is still included in the stats. Therefore, the final
counts will not reflect the entropy of the coded bits, but rather the
entropy of the combination of coded bits and the implied value (which
is always 1). Fix that by only including counts if the hp bit is
actually coded.
See issue 1060.

The normative (convolve8) filter is optimized/faster than
the nonnormative one. Pass usage of scaler (normative/nonomorative)
to vp9_scale_if_required(), and always use normative one for 1 pass.

See issue 1030. The value of frame_parallel_decoding_mode was ignored
in vp9 if refresh_frame_context was 0, so instead make it a 3-member
enum where the dependency is obviously stated.
