pngdec: add support for video/x-raw-gray formats

We work with 16-bit gray PNG images in our project, so we need support for this. I attached my patch for the pngdec. It can be applied on 0.10.30 and on master branch.

    pngdec: add support for video/x-raw-gray formats
    
    pngdec can now decode gray 8- and 16-bit images without alpha channel
    direct to video/x-raw-gray format. 16-bit gray images have big-endian
    format, because it's native PNG endianness. Gray images with alpha
    channel still converted to RGBA.
