James Zern
45daecb4f7 vp8_decode_frame: fix oob read on truncated key frame 
the check for error correction being disabled was overriding the data
length checks. this avoids returning incorrect information (width /
height) for the decoded frame which could result in inconsistent sizes
returned in to an application causing it to read beyond the bounds of
the frame allocation.

eae7cf2368 fdct16x16 neon optimization 
Roughly 2x speedup. Since the only change for HBD is to store(), the
improvement appears to hold there as well.

Fix it to the default EIGHTTAP for now, to be updated/selected
adaptively in a later change.

cb9133c72f neon variance: add small missing sizes 
Some of the mixed sizes were missing. They can be implemented trivially
using the existing helper function.

When comparing the previous 16x8 and 8x16 implementations, the helper
function is about 10% faster than the 16x8 version. The 8x16 is very
close, but the existing version appears to be faster.

10a497bd38 Make the row based multi-threaded encoder deterministic 
This patch followed allow_exhaustive_searches feature modification and
continued to modify the encoder to achieve the determinism in the row
based multi-threaded encoding. While row-mt = 1 and using multiple
threads, the adaptive feature in encoder was disabled, which gave
BDRate gain(at speed 1, -0.6% ~ -0.7%; at speed 2, -0.46% ~ -0.59%),
but some encoder speed losses(7% ~ 10% at speed 1 and 3% ~ 6% at
speed 2). These speed losses were acceptable considering the speed
gains obtained from row-mt.

bf8a49abbd Clean CONVERT_TO_BYTEPTR/SHORTPTR in convolve 
Replace by CAST_TO_BYTEPTR/SHORTPTR.
The rule is: if a short ptr is casted to a byte ptr, any offset
operation on the byte ptr must be doubled. We do this by casting to
short ptr first, adding offset, then casting back to byte ptr.
