Rather than %include'ing decode.h and potentially pickup new (unsupported functions), explicitly list the desired functions as with encode. Reorganize a bit to contain most of the language specific additions to one area. This fixes the visibility of the wrap_* functions in java. The method modifiers need to come before the function prototypes. Change-Id: I595df4d1a60edcb263923b5a2621879d3b6233cf
