This is possible now that ff_thread_await_progress() accepts
a const ThreadFrame*.

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.)

With the description in frame size with refs semantics (SPEC 7.2.5),
it is a requirement of bitstream conformance that for at least one
reference frame has the valid dimensions.
Modify the check to make sure the decoder works well in SINGLE_REFERENCE
mode that not all reference frames have valid dimensions.
Check and error out if invalid reference frame is used in inter_recon.
One of the failure case is a 480x272 inter frame (SINGLE_REFERENCE mode)
with following reference pool:
0. 960x544 LAST valid
1. 1920x1088 GOLDEN invalid, but not used in single reference mode
2. 1920x1088 ALTREF invalid, but not used in single reference mode
3~7 ... Unused
Identical logic in libvpx:

VP9SharedContext needs to be the first member so its properties can be
safely accessed from hardware accelerators, without the need to share
the full VP9Context.
Fixes ticket #6674.
