Since we're not win32-dll clean the way libtool docs define it.

With gcc on arm, request 8-bit structure alignment.

Currently doesn't handle script or direction.

We just require people to have libtool, pkg-config, etc installed
when running autogen.sh

It was unmaintained and the code has to be replaced to use the new
grphite-ng code base.

Patch from suzuki toshiya.

Graphite module not updated.
Bump version to 0.3.

Also remove wrong ASSERT_SIZE that would trigger only when not using
flexible arrays (which was the case on win32, but not with gcc).
