Work around a behaviour change in freetype > 2.8
Freetype will throw an error when we try to retrieve the glyph if the x/y
advance values are too big to fit in a 16.16 fixed point value.
Since we have no need of those values, set them to zero, and avoid the error.
Bring freetype up to 2.9.1
Plus the gs makefile changes to support the new version.
Reapply "Work around a change in the zlib API for 1.2.11"
for Freetype
