3996f3279b fix range clips for casts to and from int
Fix two bugs:

- clip in casts from int32 and uint32 could overflow -- do these as gint64 now

- clip in casts from float to int could overflow since float32 can't
  represent the full range of int32 without losing precision -- do these
  as double

And add some more tests.

Thanks ewelot.

We were not copying metadata down pyramid layers in dzsave, so
--no-strip didn't allow icc profiles on tiles.

6b2079bfd3 update magick metadata naming
IM seem to have changed their rules for naming metadata chunks. They are
now lowercase and ICM is renamed to ICC. Add a simple test too.

1e015654c3 deprecate heifload autorotate
heifload autorotate is now always on, and we always delete EXIF
orientation tags. If a HEIC image fails to rotate upright, at least it's
someone else's fault.

Fix gif dispose handling for DISPOSE_BACKGROUND and DISPOSE_PREVIOUS
- Add 'scratch' field to gif that holds temporary 'scratch buffer' used for rendering frames
- For DISPOSE_BACKGROUND: Set background color to transparent instead of 0
- For DISPOSE_BACKGROUND: Write background pixels into scratch after rendering current frame, so it will be used in next frame
- For DISPOSE_PREVIOUS: Save frames that are not disposed into 'previous' field in gif, when DISPOSE_PREVIOUS is specified start with that previous frame. see http://webreference.com/content/studio/disposal.html
- Add "ANIMEXTS1.0" to Application Extension parser
- Graphic Control Extension parser refactor
- Compare file contents to expected images for animated gifs in foreign tests

`vips_thumbnail()` was not taking a private copy of the image before
modifying metadata during auto-rotate.

e236f19f97 add fallbacks to new_from_stream
If the stream-based loaders fail, vips_image_new_from_stream() now falls
back to the old file and buffer loaders.

The file and buffer loaders already try the stream loaders first.
