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.

clip coding and interpretation on image read

They could be out of bounds enums. This used not to matter, but we use

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.

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.

much faster ismagick
...
We used to Ping files to see if IM would load them, but this can be
extremely slow for file formats like ARW.

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.
