restore bandfmt after unpremultiply in thumbnail
...
vips_unpremultiply() always outputs float. If you save the output of
vipsthumbnail to a format that supports float files, like tiff, it won't
ever get cast back to the source format.
Example:
$ vipsheader Opera-icon-high-res.png
Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload
$ vipsthumbnail Opera-icon-high-res.png -o x.tif
$ vipsheader x.tif
x.tif: 117x128 float, 4 bands, scrgb, tiffload
This change makes it note and restore BandFmt aropund pre/unpremultiply.

Fix poppler version requirement, add loader check

This fixes the poppler-glib version requirement to version 0.16, which
is the lowest version that compiles and works properly with pdfload.
Also added a check for pdfload and enabled testing on Travis CI.

Add mozjpeg quant_table option to jpegsave
...
This allows to choose from several predefined quantization tables when
libvips is compiled against mozjpeg 3.0+.
Tuning the quantization table helps to improve file size in the higher
quality range and avoid artefacts in the lower range.
