    stds.h: introduce AFS_NONNULL
    
    AFS_NONNULL wraps the GCC/Clang function attribute __nonnull__, which
    tells the compiler and the static analyzer that the pointer arguments
    to a function (or specific ones, if provided) cannot be null.  Note
    that GCC has only limited support for warning about violations of these
    constraints.
    
    Usage examples:
    int myfunc(struct foo *a, bar_t, struct baz *c) AFS_NONNULL((1));
    
    tells the compiler that the first argument cannot be null (but the
    third one can).
    
    int myfunc2(struct foo *a, bar_t, struct baz *c) AFS_NONNULL();
    
    tells the compiler that both pointer arguments cannot be null.
