Use GLib's i18n support instead of copying and pasting that

header in favour of glib/gi18n.h.
The optional parameters of vips_gaussnoise were incorrectly
passed within vips_fractsurf. This was discovered when running
the libvips testsuite on Windows 10 IoT (ARM32).
we now have VIPS_MAX_COORD for maximum image dimension, set to 10m
pixels ... we could go up to 2bn, but 10m seems a reasonable max, at
least for now
