This reflects some assumptions we have on our headers: - <openssl/foo.h> pulls in <openssl/base.h>. In particular, the canonical FOO typedefs for foo_st all live forward declared in <opessl/base.h>, but including <openssl/foo.h> is sufficient to use FOO. - <openssl/base.h> pulls in <stdint.h> and <stddef.h> so we don't have to keep including it. Add IWYU exports to reflect this so that clang's include cleaner gets less upset. It's a bit of a blunt instrument because it also means that <openssl/foo.h> lets you use the forward-declared BAR typedef, and downstream projects might still prefer to explicit include <stdint.h> when they use it (we use it so much that it would be too much), but I think this is fine. NB: By adding these, we're essentially promising we won't include those transitive includes because downstream code might accidentally start relying on it.
