Use <stdbool.h> and replace _Bool with bool.

This header is a requirement for the public API, therefore is assumed to
exist. It is a C99 standard library header, and _Bool is not intended to
be used directly, except in legacy code that defines bool (and
true/false) itself. We don't use or depend on such code. None of our
client code uses or depends on such code. There is no reason to not use
bool.
