Replace uses of the GCC __nonnull__ attribute with the clang nullability qualifiers. The replacement should be transparent for clang developers as the new qualifiers will produce the same warnings and will be useful for static checkers but will not cause aggressive optimizations. GCC will not produce such warnings and developers will have to use upgraded GCC ports built with the system headers from r312538. Hinted by: Apple's Libc-1158.20.4, Bionic libc MFC after: 11.1 Release Differential Revision: https://reviews.freebsd.org/D9004
