* changes:
  Removing CONFIG_MD5.
  Using VP9_FRAME_MARKER instead of raw number.

Change-Id: I951abd4ad0078f78949f3cb79453ac334fb82a7e

We don't need compile time md5 configuration because --md5 is a runtime
option.

vpx_codec_vp9x_cx is not used internally. Experimental flag from
vp9_extracfg is also not really used. YUV 4:4:4 just works after these
changes (you have to specify --profile=1 for the encoder).

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.

Buffer the SSE of prediction residuals in the rate-distortion
optimization loop of a given block. This information would be used
for later encoding control.

Moving all code from that files to vp9_mvref_common.{h, c}.

Change-Id: Ibc4afcb8cea6847166ff411130e93611ebe63b20

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.

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().
