Subject: Use a shared_ptr<vector> for ArrayData rather than a shared_array.

This is simpler and allows us to remove the hack of allocating some
"maximum" buffer for incoming JPEG2000 data.

It does mean that the buffer is zero-initialized before being written
to, but hopefully that doesn't matter too much.
