Fixed bug with png_handle_hIST with odd chunk length (Frank Busse). Fixed incorrect type (int copy should be png_size_t copy) in png_inflate(). Fixed off-by-one bug in png_handle_sCAL() when using fixed point arithmetic, causing out-of-bounds read in png_set_sCAL() because of failure to copy the string terminators. This bug was introduced in libpng-1.0.6 (Frank Busse). Removed the png_free() of unused png_ptr->current_text from pngread.c. Added libpng license text to pnggccrd.c and pngvcrd.c (requested by Chrome). Removed all of the assembler code from pnggccrd.c and just "return 2;".
