This fixes linking problems on OSX. Unfortunately it turns out we need to use an instance of the ``fuzzer::ExternalFunctions`` object in several places so this commit also replaces all instances with a single global instance. It also turns out initializing a global ``fuzzer::ExternalFunctions`` before main is entered (i.e. letting the object be initialised by the global initializers) is not safe (on OSX the call to ``Printf()`` in the CTOR crashes if it is called from a global initializer) so we instead have a global ``fuzzer::ExternalFunctions*`` and initialize it inside ``FuzzerDriver()``. Multiple unit tests depend also depend on the ``fuzzer::ExternalFunctions*`` global so a ``main()`` function has been added that initializes it before running any tests.
