Initialize libunwind cursors from the signal handler's ucontext_t unw_context_t is, at least on x86_64, the same type as ucontext_t. Passing that into unw_init_local doesn't work, but there's a unw_init_local2 in libunwind 1.3.0 or later, which has a flag for this case. This avoids needing to unwind past the signal handler stack frames, which is both simpler and faster. (Shaved around 10 seconds off running all the unwind tests on my machine.)

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.
