  Log Message:
  -----------
  Fix compilation errors in C API when using C compiler

* Cannot use sizeof() on another union member
* nullptr vs NULL
* () vs (void)

Incidentally, fix an incorrect comment about memory ownership on the
argument to __orc_rt_CreateCWrapperFunctionResultFromOutOfBandError,
which is copied, not moved.
