John Cupitt cfa96f735a only read ifd0 orientation
we used to set orientation from the first ifd, now just read ifd0, since
that's where the main image orientation should always be

John Cupitt bfc339facb make vips_image_write() sever connections
when writing to a non-partial image, vips_image_write() now carefully severs
all connections between the two images on completion

this fixes a couple of cases where we had bad behaviour: writing to a
temp file could leave dangling pointers, see

https://github.com/jcupitt/libvips/issues/708

and writing to a memory buffer during copy_memory coud leave dangling
pointers too, see:

John Cupitt 6f16a9df71 fix a crash with heavy use of draw
we were leaving a few bits of the original image around after
vips_image_copy_memory(), including the progress signal ... if earlier images
were freed, perhaps by a GC in a language binding, we could get a dangling
pointer
