Pull ChangeCipherSpec into the handshake state machine. This uses ssl3_read_bytes for now. We still need to dismantle that function and then invert the handshake state machine, but this gets things closer to the right shape as an intermediate step and is a large chunk in itself. It simplifies a lot of the CCS/handshake synchronization as a lot of the invariants much more clearly follow from the handshake itself. Tests need to be adjusted since this changes some error codes. Now all the CCS/Handshake checks fall through to the usual SSL_R_UNEXPECTED_RECORD codepath. Most of what used to be a special-case falls out naturally. (If half of Finished was in the same record as the pre-CCS message, that part of the handshake record would have been left unconsumed, so read_change_cipher_spec would have noticed, just like read_app_data would have noticed.)

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.
