Patch to use libraw full size data extraction to process DNG

Maik,

See my patch against git /master. I created a new
DRawDecoder::extractRawData2() method which is 80% similar than
DRawDecoder::extractRawData() excepted the RAW data extract which use the full
mosaic size instead a post-processed one done by LibRaw::raw2image() (see
DRawDecoder::extractRawData()::line #486.

In DNGWritter use the identify::fullSize instead post-processed
identify::outputSize, and now RAF are converted fine in DNG:

The orientation and colors are fine in target DNG. Only a small frame exists
around full size image. It's probably the margin to specify to the DNG SDK
during conversion.

I don't yet run the regression tests with the other RAW file formats to see if
DNG conversion work fine.

Gilles
