Clean up compiler warnings found in provisioningclient

Compiler warnings fixed are:
 - unused-parameter fixed by using OC_UNUSED macro
 - type-limits fixed by changing the return type from size_t to off_t
   that is returned by the ftello function.
 - sign-compare fixed by replacing int with size_t where needed
 - format= fixed by replacing %d in printf and scanf with PRIuPTR or SCNuPTR
   from the cinttypes header.
