Add a RelWithAsserts build configuration.

On our bots, debug unit tests take around 2.5x as long to complete as
release tests on Linux, 3x as long on macOS, and 6x as long on Windows.
Our tests are fast, so this does not particularly matter, but SDE
inflates a 13 second test run to 8 minutes. On Windows (MSVC), where we
don't but would like to test with SDE, the difference between optimized
and unoptimized is even larger, and test runs are slower in general.

This suggests running SDE tests in release mode. Release mode tests,
however, are less effective because they do not include asserts. Thus,
add a RelWithAsserts option.

(Chromium does something similar. I believe most of the test-running
configurations on the critical path run is_debug = false and
dcheck_always_on = true.)

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.
