cccad1c5de Reduce dqcoeff array size in decoder
The decoding process handles detokenization and reconstruction per
transform block sequentially. There is no need to offset the dqcoeff
buffer according to the transform block index. This allows to
reduce the memory spill and improve cache performance.

c9976b32b4 Update use_prev_frame_mvs flag in decoder.
Added check to see if last frame was all intra.  This will
eliminate two checks in find_mv_refs_idx().  Also, do not
update the frame mvs if the current frame is all intra.

This improved performance on material with frequent
intra-only frames.

bfb6d48812 Add control to skip loop filter in VP9 decoder.
This control allows the application to skip the loop filter in the
decoder. This is an advanced control that should only be used in
extreme circumstances as it may introduce and accumulate decode
artifacts.

8b17f7f4eb Revert "Remove mi_grid_* structures."
(see I3a05cf1610679fed26e0b2eadd315a9ae91afdd6)

For the test clip used, the decoder performance improved by ~2%.
This is also an intermediate step towards adding back the
mode_info streams.

3807dd82ab Make encoder buffer allocation dynamic
Frame buffers are now allocated dynamically on-demand.

Entries in the reference frame map, cm->ref_frame_map,
may now be set to -1 (INVALID_IDX) to indicate that
there is not a valid reference buffer in that "slot".

All slots in the reference frame map are now initialized
to the empty state (-1) and each buffer is initialized
to have a reference count of 0.

a723f5ecd1 Fix a tsan error bug in frame parallel decode.
A frame may be waiting for an out of border pixel from another
frame. A frame's row progress variable is set to -1 when start being decoded
and another frame may be waiting for -2 row pixel from this frame.
In this case, vp9_frameworker_wait will return directly and skip the waiting
which leads to tsan error between threads.
