block: from int64_t to int as it is a block index.
sse: from unsigned int to int64_t to reduce type conversion.

spatial/temporal scalability are not supported in VP10 currently.
+ remove the unused vp10/encoder/skin_detection.[hc]
this also enables DatarateTestLarge for VP10 which passes with no
experiments enabled. these were removed previously when only the SVC
tests should have been:

This patch just creates the interface for global motion computation
and calls it from encodeframe. Currently, the function
compute_global_motion_feature_based is empty and the work to do
the actual parameter calculation will be added in a future patch.

- Avoid some memcpy()s
- Remove indices array
- Make pre_indices array local
- Avoid rounding twice
- Other small simplifications

This patch only includes inter frame reconstruction using gm
parameters when GLOBAL_MOTION and/or VP9_HIGHBITDEPTH are enabled.
GM is not currently used when EXT_INTER or DUAL_FILTER is enabled.
This will be added in a followup patch. For now, these experiments
will take precedence over GLOBAL_MOTION when they are all enabled.

- Add unit tests to verify the bit-exact result.
- In speed test, function speed (for each mode/tx_size)
improves about 23%~35%.
- On E5-2680, park_joy_1080p, 10 frames, --kf-max-dist=1,
encoding time improves about 1%~2%.

(1) Key frame: skip filter intra modes whose directional pred
version is relatively bad (rd >= 1.125 * best_rd)
(2) Inter frame: do not check filter intra modes if best_intra_rd
>= 1.25 * best_rd
Encoding time overhead is reduced by:
4.9% (9.2%->4.3%, soccer_cif)
Coding gains drop by 0.021% on lowres and by 0.076% on midres

The ARF Index was wrong when updating the upsampled reference
frame buffer.
Compared to the baseline in which multi_arf_allowed is disabled, the
RD performance drops 2.250% in Avg using Overall PSNR in the derf
dataset. The performance decrease is especially in the following
video sequences:
foreman_cif: drops 7.489%
husky_cif: drops 6.421%
soccer_cif: drops 4.850%
However, it has a significant gain in the following video sequences:
container_cif: increases 8.043%
harbour_cif: increases 1.332%

We have renamed following Macros to avoid name confusion:
REFS_PER_FRAME --> INTER_REFS_PER_FRAME
(= ALTREF_FRAME - LAST_FRAME + 1)
MAX_REF_FRAMES --> TOTAL_REFS_PER_FRAME
(= ALTREF_FRAME - INTRA_FRAME + 1)
INTER_REFS_PER_FRAME specifies the maximum number of reference frames
that each Inter frame may use.
TOTAL_REFS_PER_FRAME is equal to INTER_REFS_PER_FRAME + 1, which
counts the INTRA_FRAME.
Further, at the encoder side, since REF_FRAMES specifies the maximum
number of the reference frames that the encoder may store, REF_FRAMES
is usually larger than INTER_REFS_PER_FRAME. For example, in the
ext-refs experiment, REF_FRAMES == 8, which allows the encoder to
store maximum 8 reference frames in the buffer, but
INTER_REFS_PER_FRAME equals to 6, which allows each Inter frame may
use up to 6 frames out of the 8 buffered frames as its references.
Hence, in order to explore the possibility to store more reference
frames in future patches, we modified a couple of array sizes to
accomodate the case that the number of buffered reference frames is
not always equal to the number of the references that are being used
by each Inter frame.

The gm parameters need to have WARPED_PRECISION_BITS precision
until they are written to the bitstream because functions in
reconinter use these parameters before they are written to
the bitstream. Previously, the parameters weren't being converted
to WARPED_PRECISION_BITS until they were read from the bitstream
which causes an encode/decode mismatch.

(1) Apply ALLOW_FILTER_INTRA_MODES flag to the correct place, otherwise
there are bitstream mismatchs when it is 0.
(2) Rename pick_ext_intra_iframe() to pick_ext_intra_interframe().
