Import upstream's tests for DES_ede3_cfb_encrypt

Upstream does not actually have any tests for DES-EDE3-CFB, with the
exception of a single DES-EDE3-CFB1 test vector, only the single-DES
version. But we can gain some coverage by turning 3DES back into single
DES with a repeated key. That's good enough for DES.

The DES-EDE3-CFB1 test vector is unusable because that tests
EVP_des_ede3_cfb1, the real DES-EDE3-CFB1. OpenSSL's low-level APIs do
not actually implement CFB correctly for a non-whole-number of bytes!
See discussion in the test. I've added coverage for that case by just
fabricating a test vector.

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.
