Correctly order PKCS#7 certificates and CRLs. PKCS#7 stores certificates and CRLs in (implicitly-tagged) SET OF types. This means they're unordered and, in DER, must be sorted. We currently sort neither. OpenSSL upstream sorts CRLs but doesn't sort certificates. https://github.com/openssl/openssl/pull/13143 reports that Microsoft has a stricter parser that checks this. This CL fixes both fields in our serializer. This does not change the parsing code, which still preserves whatever order we happened to find, but I've updated the documentation to clarify that callers should not rely on the ordering. Based on [0] and the odd order in kPKCS7NSS, I believe this aligns with NSS's behavior. Update-Note: It is no longer the case that constructing a PKCS#7 file and parsing them back out will keep the certificates and CRLs in the same order.

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.
