Subject: [C23 divers headers 09/17] C23: update stdbool.h
C23 has false, true and bool as keywords, so this file is basically
not needed for modern applications. It is only provided for backwards
compatibility. Implementations may also provide macros in addition to
the keywords, so we do that because some user code may rely on these.
