C_InitI2P is compatible with more things if it passes argv by reference, it would appear. So to pass arguments to InitI2P you need to turn them back into char* argv[] by tokenizing them and copying them into an array which you then pass to InitI2P from C_InitI2P. The Streaming and Destination Creation parts need to have wrappers for over Identity.h, Streaming.h to be useful so remove them.
