75b6cfe1c5 Prevent read to invalid RefBuffer 
This commit adds check to validate RefBuffer before reading into the
data structure, to prevent invalid read.

a5191f3e60 Move, rename, and inline high_inter_predictor. 
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.

d8aa40634a VP9: Eliminate unnecessary nearest/near searches

search for ZEROMV modes and breaks out early for NEARMV and
NEWMV modes.

2bd4f44409 Assert no mv clamping for scaled references 
Under --enable-better-hw-compabibility, this commit adds the asserts
that no mv clamping is applied for scaled references, so when built
with this configure option, decoder will assert if an input bitstream
triggger mv clamping for scaled reference frames.

8f7bc45b5b Revert "VP9: Only zero counts when !frame_parallel_decoding_mode" 
This reverts commit 380a5519cc.

This causes an assertion failure in debug_check_frame_counts() which
probably isn't valid with this change; leaving the investigation for
later now.

7718117104 VP9: move loopfilter build masks to decode loop 
The loopfilter masks are now built in the decode loop.
This is done so we can eventually reduce the number of
MODE_INFO structs required by the decoder.

The encoder builds the masks for the entire frame prior
to calling the loopfilter.

812945a8f1 vp9/10: improve support for render_width/height. 
In the decoder, map this to the output variable vpx_image_t.r_w/h.
This is intended as an improved version of VP9D_GET_DISPLAY_SIZE,
which doesn't work with parallel frame decoding. In the encoder,
map this to a codec control func (VP9E_SET_RENDER_SIZE) that takes
a w/h pair argument in a int[2] (identical to VP9D_GET_DISPLAY_SIZE).

Also add render_size to the encoder_param_get_to_decoder unit test.

See issue 1030.
