[Java] Dataset JNI bridge should use the C data interface

[asfimport]

Right now the datasets JNI bridge uses some custom buffer passing which only seems to handle primitive arrays correctly (child array buffers and dictionaries are not considered):

Instead, it should use the C data interface, which is now implemented in Java.
