For now, give the unsuffixed ChaCha20 AEAD name to the old version.

QUIC has a complex relationship with BoringSSL owing to it living both
in Chromium and the Google-internal repository. In order for it to
handle the ChaCha20-Poly1305 AEAD switch more easily this change gives
the unsuffixed name to the old AEAD, for now.

Once QUIC has moved to the “_old” version the unsuffixed name can be
given to the new version.

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.
