make out of order read a fatal error
...
For png and jpg, out of order must always be a fatal error, since you
can't read from a specific y position.
This was a g_assert() before which meant that this test was missing from
production builds. It's now always a fatal error.

more careful p->t conversion
...
When we convert an image from "p" to "t" in vips_image_wio_input(), zap
start/gen/stop callbacks. This makes vips_region_prepare_to() read from
the "t" rather than trying to gen pixels again.

pngsave interlaced makes a copy of the image
...
interlaced png is hard to write: you have to make seven passes over the
image to make the whole file. It advertises itself as sequential, it
needs to only ake a single pass. Therefore, it must take a copy in
memory of the image to write.

They are now combined in the single vips_image_pipeline() call.
All operations are now slightly smaller and simpler.
