    androidmedia: add gst_amc_color_format_copy

    gst_amc_color_format_copy will copy in/out a frame resides at a
    GstAmcBuffer. Lots of codes in gst_amc_video_*_fill_buffer are moved to
    this new function.

    androidmedia: move create_src|sink_caps to gstamc.c

    Some hack logic needs also to be present in create_src|sink_caps, for
    working around some broken codecs. These hacks are hidden
    in color_format/video_format conversion -- the prototypes of these
    functions are also changed to include more args for hack judgement.

    Also in case of multi-color_formats mapped to one video_format, then
    map that video_format back will not give the original color_format, which
    causes gst_amc_codec_configure failed with something like
    'does not support color format N'.

    The new prototype involves with GstAmcCodecInfo and mime, which
    ensures the converted color_format is supported by the codec.

    A COLOR_FormatYCbYCr to GST_VIDEO_FORMAT_YUY2 mapping is also added, in
    order to work around bugs in OMX.k3.video.decoder.avc(which incorrectly
    reports supporting COLOR_FormatYCbYCr, which is actually
    COLOR_FormatYUV420SemiPlanar). There are already hacks for this in
    gst_amc_video_format_to_color_format, gst_amc_color_format_to_video_format
    and gst_amc_color_format_info_set, but the codec will still not work(be
    ignored because of "has unknown color formats") without adding this
mapping.
