Brian Smith a432757acb Use BN_mod_inverse_odd instead of |BN_mod_inverse| for ECC. 
BN_mod_inverse_odd was always being used on 64-bit platforms and was being used
for all curves with an order of 450 bits or smaller (basically, everything but
P-521). We generally don't care much about minor differences in the speed of
verifying signatures using curves other than P-256 and P-384. It is better to
always use the same algorithm.

This also allows |bn_mod_inverse_general|, |bn_mod_inverse_no_branch|, and
|BN_mod_inverse| to be dropped from programs that can somehow avoid linking in
the RSA key generation and RSA CRT recovery code.

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.
