Fix up BN_MONT_CTX_set with non-minimal values. Give a non-minimal modulus, there are two possible values of R we might pick: 2^(BN_BITS2 * width) or 2^(BN_BITS2 * bn_minimal_width). Potentially secret moduli would make the former attractive and things might even work, but our only secret moduli (RSA) have public bit widths. It's more cases to test and the usual BIGNUM invariant is that widths do not affect numerical output. Thus, settle on minimizing mont->N for now. With the top explicitly made minimal, computing |lgBigR| is also a little simpler. This CL also abstracts out the < R check in the RSA code, and implements it in a width-agnostic way.

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.
