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.

3ea72c286e improve fuzz targets and oss-fuzz integration 
It replaces current fuzz setup with 5 new fuzzers integrating them with
top-level Makefile. It now supports multiple fuzzing engines and Google's
oss-fuzz. By default, the fuzzers are linked against an standalone runner to
easily reproduce bugs.

f45f0ecef4 limit resize if shrink would drop axis <1px 
vips_resize() will break the aspect ratio and limit resize on an axis if
it would result in an image of less than 1px on that axis

26100041e7 fewer warnings on tiffload 
We were setting TIFFTAG_JPEGCOLORMODE == JPEGCOLORMODE_RGB for *all*
images, but libtiff warns if you use it on an image which is not
jpg-compressed.

Only set it for jpg-compressed images.
