Adding RefBuffer to simplify reference buffer management. The struct has a
pointer to image data and scale factors relative to the current frame.

This commit takes a preliminary attempt to refine the motion search
control. It detects the SAD associated with mv predictor per reference
frame, and based on which to determine whether the encoder wants to
reduce the motion search range (if the predicted mv provides fairly
small SAD), or to skip the current reference frame (if there exists
another ref frame that gives much smaller SAD cost).

This feature is turned on in the settings of speed 1 and above.

Moving back to scale_factors struct. We don't need anymore x_offset_q4 and
y_offset_q4 because both values are calculated locally inside vp9_scale_mv
function.

Change-Id: I78a2122ba253c428a14558bda0e78ece738d2b5b

Before mv scaling it is required to calculate x_offset_q4/y_offset_q4
by calling set_scaled_offsets(). Now offset configuration can not be
missed because it happens just before scale_mv().

This commit reworks the prediction filter rate-distortion cost update
process consistent for all block sizes.

Change-Id: I5874349ab38df380240f96c2d4ef924072bab68d

Various cleanups and refactoring.
Removes feedback of active worst qaulity and uses last_q
instead to make the interface cleaner. Active worst quality
is now decided only once for a frame being coded in the
beginning based on last_q and other stats. Also, adds other
cleaups on last_q to store also the last_q for altref frames,
and reduces the altref interval a little.

The output does change a little.

This commit enables an adaptive prediction filter type selection
for sub8x8 block sizes. In speed 1, it re-uses the filter type of
collocated 8x8 block if it is tested in the rate-distortion optimization
loop, for the sub8x8 blocks. Otherwise, it runs the normal test
over all the three filter types. In speed 2, it re-uses the 8x8
block's prediction filter type, if available. Otherwise, force it
to be EIGHTTAP.
