Convert by value passing of nfc_target to pointer for str_nfc_target and nfc_initiator_target_is_present

Browse Source 
This becomes more consistent with all other pass by pointer of most structures.
Additionally, this should lessen stack memory usage, as building strings with str_nfc_target would push the target (283 bytes) plus then a copy of the info objects (up to 275) onto the stack as it dives into the sprintf functions.

Lastly, this makes my attempt at a .NET wrapper easier, as I can make passing by pointer work, but passing by value seems to bomb on the interop right now.
