Brian Smith 3426d10119 Convert RSA blinding to use Montgomery multiplication. 
|BN_mod_mul_montgomery| has better constant-time behavior (usually)
than |BN_mod_mul| and |BN_mod_sqr| and on platforms where we have
assembly language optimizations (when |OPENSSL_BN_ASM_MONT| is set in
crypto/bn/montgomery.c) it is faster. While doing so, reorder and
rename the |BN_MONT_CTX| parameters of the blinding functions to match
the order normally used in Montgomery math functions.

As a bonus, remove a redundant copy of the RSA public modulus from the
|BN_BLINDING| structure, which reduces memory usage.

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.
