ff58c67e33 add locks for pdfium load 
We used to lock within documents, ie. we did not allow two threads to
work on the same file.

However pdfium is not threadsafe in any way, and this is not supported,
see:

	https://groups.google.com/forum/#!msg/pdfium/kyIdh_J4csg/K1LvfPiHDwAJ

This patch adds locks around pdfium calls.

0d2c14c967 try to improve pthread discovery 
we were not using all the flags we should when testing for
pthread_setattr_default_np() ... place the test line after GTHREAD and
use those flags for linking

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

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
