Fix up BN_GENCB_call calls. Use the constants when defined. Also OpenSSL uses 0-indexed iteration counts rather than 1-indexed. This likely changed when we tried to align with the 1-indexed FIPS 186-4 algorithm. Also fix the safe prime call. BN_GENCB_call(cb, i, c1 - 1) doesn't make sense since the first parameter should be an event constant. OpenSSL does BN_GENCB_call(cb, 2, c1 - 1). This also doesn't make sense. OpenSSL documents 2 as meaning the prime has been found. That function is interleaving the p and (p-1)/2 checks to save the full iteration count on p if (p-1)/2 is composite anyway. That also doesn't work because the blinding mechanism runs even if the iteration count is 1, so we're actually paying for the blinding four times. Add a TODO to address this. (I can only assume we just never try to generate safe primes. Moreover, we don't even use BN_generate_prime_ex in RSA keygen. Still, that function needs work.)

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.
