Mark some transitive includes as IWYU export.

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.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.

To file a security issue, use the Chromium process and mention in the report this is for BoringSSL. You can ignore the parts of the process that are specific to Chromium/Chrome.
