John Bowler 1a9eb510eb [libpng17] Moved READ_GAMMA to pngrtran.c. This makes everything in pngrtrans.c ...

depend on READ_TRANSFORMS and moves all the transform gamma (READ_GAMMA)
code from elsewhere to png_tran.c.  There are no code changes.
There is one remaining use of the gamma (16-bit) code in the simplified
API in pngread.c but that is because of a long-standing libpng bug,
namely that the gamma corrected palette is no produced by
png_read_update_info (John Bowler).
