Remove X509_VERIFY_PARAM_get0_peername

This allowed the caller to query which DNS SAN actually matched. It's
not an unreasonable API, though putting it on X509_VERIFY_PARAM is a
little odd, as is not having it for other name types. It just wasn't
const-correct. I went to fix that and found no one was using it.

We can put it back if we need it. Most of the underlying machinery needs
to stay anyway because X509_check_host has an output parameter and Node
exposes it. (Unclear if Node actually has a use case. I suspect they
just returned it because it was available.)

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.
