6956bcf8a4 Fix several problems with gi path warnings 
* Do not warn when the prefix appears to be a homebrew cellar.
* Fix configure errors when python is not detected
* Fix configure errors when pygobject is installed in prefix but
  not present in the python `sys.path`.
* Use the actual overrides path, instead of the gi module path.

f0a5ac5bbc Vendor python.m4 to fix wrong multiarch exec paths 
The python.m4 that ships with automake hardcodes the library path for
platfrom dependent files to `lib`, which is wrong for multiarch systems.

Instead we import the `m4/python.m4` from pygobject, which does not have
this problem and also ensures we have the same behavior as pygobject
which we are depending on for pyvips8.

Due to this change some minor changes to how the `bootstrap.sh` script
clean up the `m4` folder where needed.

The python search order has been modified to prefer the default python
over python2 over python3.

54d8e4808f 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.

bec6b174c9 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.

c5fa0e1feb 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.
