    Prevent undefined behaviour for AMVR experiment · bf2cc016
    Imdad Sardharwalla authored
    Sequences starting with intra-only frames previously resulted in undefined
    behaviour with CONFIG_AMVR == 1, as seq_force_integer_mv was only read for
    keyframes.
    
    This patch makes changes as follows:
    
    - The syntax element force_screen_content_tools has been added to the
      SequenceHeader struct, and is read and written correspondingly
    
    - seq_force_integer_mv has been renamed to force_integer_mv and moved to the
      SequenceHeader struct, and is read and written correspondingly (provided that
      force_screen_content_tools != 0)
    
    - The conditional reading/writing of allow_screen_content_tools now happens for
      every frame after reading/writing error_resilient_mode (CONFIG_OBU == 1) or
      the sequence header (CONFIG_OBU == 0)
    
    - The conditional reading/writing of cur_frame_force_integer_mv now happens for
      every frame after reading/writing allow_screen_content_tools
