Use Index/Address/Offset instead of uint32_t (#433)

An `Index` is an index into one of the WebAssembly index spaces. It also
is used for counts for these spaces, as well as parameter counts and
result counts.

An `Address` is an index into linear memory, or the size of a data
region in linear memory.

An `Offset` is an offset into the host's file or memory buffer.

This fixes issue #322.
