7acfabbc40 7-bit interpolation filters 
Purpose:
-Reduce dynamic range of interpolation filter coefficents from 8
bits to 7 bits.
-Inner product for 8-bit input data can be stored in a 16-bit signed
integer.

Impact on compression efficiency:
-Marginal improvement, typically less than 0.5% BDR.

81fd890773 Linearize extrabits writing. 
The decoder is already linear so changing these tables would just create
a mismatch.

9d07888350 Fix to make intra_only frames decodable out of order 
last_frame_type is not well defined for intra_only frames
if we are decoding them out of order.
This change removes a dependency on last_frame_type for these frames.

c9862e05f5 Add a decoder control to retrieve accounting data. 
This decoder control requires AV1 to be compiled with --enable-accounting.

 decoded.
