Remove |EC_POINTs_mul| & simplify p256-x86_64.

Without |EC_POINTs_mul|, there's never more than one variable point
passed to a |EC_METHOD|'s |mul| method. This allows them to be
simplified considerably. In this commit, the p256-x86_64 implementation
has been simplified to eliminate the heap allocation and looping
related that was previously necessary to deal with the possibility of
there being multiple input points. The other implementations were left
mostly as-is; they should be similarly simplified in the future.

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.
