Required for frame-based multithreading

Change-Id: I361ec468b5bda7836116c5f0bf3a83f60c214a73

Interleaved loopfiltering with decode.  For 1080p clips, up to 1%
performance gain.  For 4k clips, up to 10% seen.  This patch is required
for better "frame-based" multithreading.

predict_d has become canonical. Remove previous helper function.

Disable ARM assembly pending update.

Rename the local variables for consistency.

Use the _d variant from the decoder. It moves the pointer calculations
to the caller.

The ambient qp and active worse/best qp were reset for every frame
when temporal layers is on. This change removes this reset.

As this affects the target size for forced key frames
(it will actually lower the size somewhat), we increased the
inital boost factor to compensate.

SAD returns unsigned values. Make all the declarations the same.

Remove bestsad initialization and check. It is always set to the
result of a SAD call so it will never remain UINT_MAX

Use ja instead of jg to test unsigned comparison instead of signed.

Update test.

Precalculated block ptrs do not need updates during encoding.
Set these at init stage.

Moved the allocation of 'mt_current_mb_col' (last encoded MB on each
row) to vp8_alloc_compressor_data(), so that it is correctly
reallocated when frame size is changing.

Added drop_frame support in multi-resolution encoder.

If one frame is dropped at a lower-resolution level, the next
upper-resolution level encoder needs to encode that frame
independently without any lower-resolution level motion
information.

Another issue is that if one frame is dropped at some but not all
resolution levels, a frame after that one may use different set
of reference frames at different resolution levels. This reference
frame asynchronization could degrade motion search precision in
upper-resolution level encoding, which uses lower-resolution level
motion result. This change compares the lower-resolution and upper-
resolution level's reference frames. If they are not the same, the
upper-resolution level encoder can not use lower-resolution level
motion result.

Added validity checking in multi-res encoder. Disable spatial
resampling and frame dropping before we have those supports.
Also, deallocate the memory for all resolution levels once error
occurs.
