Adds a non-normative resize library to vp9 encoder Adds an arbitrary-size resize library for use in scaling of input frames in a non-normative manner in the vp9 encoder. The method used is as follows: Downsampling - Uses a 8 tap filter for factor of 2 decimation upto a size just higher than the desired size. Then interpolates pixels at a precision of 1/32 pel using a set of 8-tap filters. Upsampling - Interpolates pixels at a precision of 1/32 pel using a set of 8-tap filters. There is no assembly optimization yet. Change-Id: Ib5b81e174fc139da322bb97c8214d52289d60d8a
