d80ce4bf15 fix a problem with shrinkv tail processing 
Tail processing in shrinkv had an implicit assumption of round-down, but of
course we round to nearest. Thanks angelmixu.

faafd4eee0 try disabling IM for oss-fuzz 
libvips has to use ReadImage() when it opens an image via MagickCore,
and this can allocate very large amounts of memory, killing the fuzzer.

IM is already part of oss-fuzz, so we are not gaining much by
replicating that work. This patch attempts to disable IM for fuzzing tests.

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.
