Our custom UNUSED_ARGUMENT macro was redundant with the sys/defs.h __unused macro, so it needed to be removed. But rather than switch to __unused, we opt to switch this code to C++, so we can comment out parameter names to silence compiler warnings about unused arguments. The switch to C++ requires casting the result of calloc. We also change our function argument indentation per our C++ style rules while we're in here. Test: Compiled and confirmed no compiler warnings. Change-Id: Ibd0eef7787843597917c3e0e71bdd772f6e9e876
