46212e92b1 fix default sharpen 
sharpen with sigma 0.5 was doing nothing, since the new int precision
rules meant that we generated a point-point convolution.

This patch increases the int precision for sharpen, so we now work with
sigma down to 0.5.

Also: restore input colourspace. Previously, the output image was always
LabS (the computation space for sharpen). Now, it transforms back to the
input space. This is more in line with how other operators work.

Thanks 2h4dl for pointing this out.

ed2054dbbc revise arithmetic with const 
there's a problem with out of bounds values, for example:

	vips relational_const k2.jpg x.v equal 1000

actually finds pixels == 255, since 1000 is saturated converted to 255
before the test starts.

This patch reworks arithmetic against const values to fix this.

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.

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.

eb6c803481 istiff tests first dir rather than magic number 
We were testing for TIFF by checking the magic number at the head of the
file. However, formats like ARW are TIFF-like without being TIFF, and
will not load with tiffload.

Instead, try reading the whole of the first directory. This is enough to
stop tiffload trying to load files where it will simply fail
immediately, and make libvips fall back to eg. imagemagick.
