this fixes a crash in vp9_dec_setup_mi() via
vp9_init_context_buffers() should decoding continue and the decoder
resyncs on a smaller frame

* changes:
Use common transpose for vpx_idct32x32_1024_add_neon
Use common transpose for vpx_idct8x8_[12|64]_add_neon
Use common transpose for vp9_iht8x8_add_neon
Use common transpose for vpx_idct16x16_[10|256]_add_neon
Safer to have the decoder operate normally and have
better-hw-compatibility only implement encoding changes.
Fixes some test failures.

The transform block row and column positions are always available
outside the callees. There is no need to re-compute these values
again. This approach has been used by the decoder. This commit
removes txfrm_block_to_raster_xy() function.

Bug fix: The crash is caused by not allocating buffer for prev_mip in
postproc_state and prev_mip in postproc_state is only used for MFQE,
ohter postproc modules, deblocking and etc., should not use it.

add a trailing ':', though it's optional with the tools we support, it's
more common to use it to mark a label. this also quiets the
orphan-labels warning with nasm/yasm.

This commit adds an encoder workaround to support better
compatibility with a non-compliant hardware vp9 profile 2 decoder.
The known issue with this decoder is:
The decoder assumes a wrong value, 127 instead of the correct
value of 511 and 2047, for any assumed top-left corner pixel in
UV planes for 10 and 12 bit, respectively. Such assumed
top-left corner pixel is used for INTRA prediction when a real
decoded/reconstructed pixel is not avalable, e.g. when it is
located inside the row above the top row or inside the column
left to the leftest column of a video image.

This reverts commit be12fefa4b
and commit 057c1c4034.
Also, the mismatch between the avx version and the
c version has been fixed.

Reduce operations and jumps. perf shows CPU time reduced from 1.9% to
1.6% when decoding fdJc1_IBKJA.248.webm on Xeon E5.
Will apply the changes to vp10 after code review.

Function level timing test shows about 27% time saving on
a Xeon E5-2680 v2 desktop.
Rename vp9_dct_sse2.c to vp9_dct_intrin_sse2.c for vp9 and
rename dct_sse2.c to dct_intrin_sse2.c for vp10 to avoid
duplicate basenames.
Actually vp9_fwht4x4_mmx/sse2() and vp10_fwht4x4_mmx/sse2()
are identical. TODO: They should be unified later if there is
no intention to keep a duplicate.

The inlining mirrors what was done with the low bit depth
inter_predictor. And the new highbd_inter_predictor name is more
consistent with other high bit depth functions.

Add control API VP9E_SET_TARGET_LEVEL that allows the encoder to
control the output bitstream level and/or keep level related
statistics.
Usage:
255 do not care about level (default)
0 keep level related stats only
10 target for level 1
11 target for level 1.1
.

.
62 target for level 6.2

In Aq mode 1 the segment and AQ delta for each block is based
on spatial variance. There may be a net imbalance between blocks
that have lower Q than the baseline value and those that have higher Q.
This patch monitors that imbalance and extends the allowed baseline
Q range for the frame to accommodate adjustment of that baseline value
to compensate.

Removed this todo because of another todo which says none of this code
should exist. It should be integrated into the block by block encode
process as per the decoder.
