Added a ARG_UNUSED macro in utils/magic.h, which produces a simple cast to void to silence the warnings. The reasons this is used as opposed to an attribute is that most compilers should support this. Besides this, the macro can be easily searched for in the future to potentially remove (where possible) the unused parameters.
