0accdf858b band large image during fuzzing 
Large images cause a lot of uninteresting OOMs and timeouts during
fuzzing. Ban them.

5e77ab948b fix loop with malformed ppm 
skip_line in ppm parse was not testing for EOF, so it could get stuck
with malformed files

5ef14db544 put close-on-last-line back for jpg/tif/png 
consider something like:

$ vips arrayjoin "$(echo *.jpg)" x.tif --across 10 --vips-progress

close on minimise won't close until the whole pipeline finishes, so
we'll need to keep every input file open

close on last line will shut down inputs as we are done with them, so we
save a lot of file descriptors

this patch puts close-on-last-line back for jpg/tif/png

55ae22608f nope, revert 
it's not possible to get inisert to trigger minimise reliably, since
threads can be out of order in the middle of the pipeline

we need to add minimise on Y (as before) to get reliable behaviour for
this case

2c654060f9 experiment with a different early-close strategy 
We close loaders early in order to save file handles, and on Windows to
make sure that files can be deleted as soon as possible.

Currently loaders do this by watching the Y coordinate of requests and
freeing the fd when the final line of the file is fetched. This is messy
and does not always work, since there are cases when the final line is
not fetched.

Instead, this patch gets loaders to listen for "minimise" on their
output and close on that. This signal is emitted on all upstream images
whenever a threadpool finishes a scan of an image and is usually used to
trim caches after computation.

8cf6a9f9ca don't attempt to save large XMP to JPG 
jpeg_write_marker() with some libjpeg versions will throw a fatal
error with large chunks.

To write >64kb XMP it you need to parse the whole XMP object,
pull out the most important fields, code just them into the main
XMP block, then write any remaining XMP objects into a set of
extended XMP markers.

http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/xmp/pdfs/XMPSpecificationPart3.pdf

Instead, just warn and skip large XMP blocks.
