Replace vp9_ prefix with vpx_ for common multi-threading functions.

Change-Id: I941a5ead9bfe8213fdad345511d2061b07797b55

This commit moves the primitive multi-threading files from vp9
folder to vpx_thread, which will be accessible by all vpx codec.

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.

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.

moving to the vpx_dsp location, place the defines used in the

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

Refactor the loops in dec_build_inter_predictors to try and decrease
the number of instructions. Limited testing saw about 1% perf
increase on x86 and about 0.67 % perf increase on Arm.

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.

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.

This patch continues the work to remove frame_parallel_decoding_mode
requirement in VP9 multi-threaded tile decoder. In order to do that,
the frame counts associated to each thread need to be accumulated
together after the frame is decoded.
