fae5d9cc82 improve configure summary table 
- order and group summary
- list by file format type, rather than library
- describe as load/save rather than import/export
- also --vips-config output

I split the VIPS_CFLAGS, VIPS_INCLUDES and VIPS_LIBS var settings into
the various finders for maintainability.

we actually test vipsthumbnail --linear on an RGBA image, which should

d3ccadf212 revise unpremultiply, again 
We were not detecting division by zero carefully enough, nor clipping
the alpha range sufficiently in unpremultiply.

see https://github.com/libvips/libvips/issues/1941

also see https://github.com/libvips/libvips/pull/1675 for another
difficult test case
