  Speed up mode search depending on relative ref frame position

  This commit enables the encoder to record the location of the
  center frame to generate alter reference frame. It then allows to
  skip checking prediction modes of other reference frame types when
  it comes to encode this frame.

  The speed 3 runtime is reduced for the test sequences :
  bus at CIF 1000 kbps, 9791 ms -> 9446 ms, i.e., 3.5% speed-up,
  pedestrian at 1080p 2000 kbps, 184043 ms -> 175730 ms, i.e., 4.5%
  speed-up.

  No compression performance change observed.

  From 3 to 2, which seems to be slightly positive on compression for
  all test sets, also reduces encoding time by 2%-5%, varying on the
  test clips.
