Provide prototypes for setup and teardown test case functions as making them static is not possible due to weak linking. Provide prototype for ctest_main function as making it static might break existing code if someone does `#define ctest_main main`. This eliminates "no previous prototype for function '...' [-Wmissing-prototypes]" Clang warning.
