John Bowler 6803b09cb7 Fixes for !READ_INTERLACE/!READ_PNG interpendencies
The reliance of png_read_png on interlace handling and some minor issues in the
test programs where they failed to correctly check for interlace handling were
exposed by the ability to write interlaced images even if WRITE_INTERLACING is
turned off.  This is fixed here.
