Make BN_clear_free a wrapper around BN_free. We clear all heap memory on free now, thus the difference between these functions is quite small. There are some differences though: Firstly, BN_clear_free will attempt to zero out static limb data. But static data is probably read-only and thus trying to zero it will crash. Secondly it will try to zero out the BIGNUM structure itself. But either it's on the heap, and will be zeroed anyway, or else it's on the stack, and we don't try and clear the stack in general because the compiler is duplicating bits of it at will anyway.

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.
