Const-correct sk_FOO_deep_copy's copy callback.

This aligns with upstream OpenSSL, so it's hopefully more compatible.
Code search says no one outside of the project uses this function, so
it's unlikely to break anyone.

Whether it makes things better is a bit of a wash: OBJ_dup and
OPENSSL_strdup loose a pointless wrapper. X509_NAME_dup gains one, but
hopefully that can be resolved once we solve the X509_NAME
const-correctness problem. CRYPTO_BUFFER_up_ref gains one... really
FOO_up_ref should have type const T * -> T *, but OpenSSL decided it
returns int, so we've got to cast.

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.
