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.

Add alpha_q(uality) webpsave option, fix Q init
...
This allows to control the fidelity of the alpha channel by allowing
webp to reduce the number of palette entries from 256 at alpha_q=100
to 2 at alpha_q=0. This is most useful with cutout pictures where
something like alpha_q=30 or around 8 levels is usually sufficient
for smooth outlines.
For some reason webp->Q was intiailized to 80 even though the Q option
and libwebp use 75 by default. This was never used, so it's just to
avoid confusion about what default is used.

Add webpsave near_lossless support, fix Q range
...
The near_lossless option allows to enable preprocessing for the lossless
mode. This is a boolean instead of an int, because the amount of
preprocessing is controlled using the Q factor parameter which is
otherwise unused in lossless mode. This allows to re-use the quality
setting in existing tools.

New webpsave option smart_subsample
...
This enables a high quality RGB to YUV converter in libwebp which
greatly improves the quality of fine details by reducing color bleeding
caused by the 4:2:0 chroma subsampling. This is slower and causes
slightly larger files. See WebPPictureSmartARGBToYUVA in libwebp.
