Changes in this patch include
[x] Long is used to store native pointers as they can
be 64-bit.
[x] Some minor changes have been done to conform with
standard JNI practice (e.g. use of jint instead of int
in JNI function prototypes)
[x] AssetAtlasManager is not completely 64-bit compatible
yet. Specifically mAtlasMap member has to be converted
to hold native pointer using long. Added a TODO to
AssetAtlasManager.java to indicate the change required.
