Instead replace VP56mv by new and identical structures VP8mv and VP9mv. Also replace VP56Frame by VP8FrameType in vp8.h and use that in VP8 code. Also remove VP56_FRAME_GOLDEN2, as this has only been used by VP8, and use VP8_FRAME_ALTREF as replacement for its usage in VP8 as this is more in line with VP8 verbiage. This allows to remove all inclusions of vp56.h from everything that is not VP5/6. This also removes implicit inclusions of hpeldsp.h, h264chroma.h, vp3dsp.h and vp56dsp.h from all VP8/9 files. (This also fixes a build issue: If one compiles with -O0 and disables everything except the VP8-VAAPI encoder, the file containing ff_vpx_norm_shift is not compiled, yet this is used implicitly by vp56_rac_gets_nn() which is defined in vp56.h; it is unused by the VP8-VAAPI encoder and declared as av_unused, yet with -O0 unused noninline functions are not optimized away, leading to linking failures. With this patch, said function is not included in vaapi_encode_vp8.c any more.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
