Keep the encryption state and encryption level in sync. This is a little bit of internal cleanup. The original intent was so QUIC could install secrets in set_(read|write)_state, but that was somewhat annoying, so I've left it just before the call for now. There is one TLS 1.3 state transition which doesn't carry an encryption level: switching from 0-RTT keys back to unencrypted on an HRR-based 0-RTT reject. The TCP code doesn't care about write_level and the QUIC code is currently fine because we never "install" the 0-RTT keys. But we should get this correct. This also opens the door for DTLS 1.3, if we ever implement it, because DTLS 1.3 will need to know which level it is to handle 0-RTT keys funny. (Clients sending 0-RTT will briefly have handshake and 0-RTT write keys active simultaneously.) QUIC has the same property, but we can fudge it because only the caller is aware of this.

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.
