Doug Kwan 5f04b6bc3a Add ppc64le vector implementation of SHA-1. 
This change contains a C implementation of SHA-1 for POWER using
AltiVec. It is almost as fast as the scalar-only assembly implementation
for POWER/POWERPC family in OpenSSL but it is easier to maintain and it
allows error checking with tools like ASAN.

This is tested only for ppc64le. It may nor may not work for other
platforms in the POWER/POWERPC familiy.

Before:

SHA-1 @ 16 bytes: ~30 MB/s
SHA-1 @ 8K: ~140 MB/s

After:

SHA-1 @ 16 bytes: ~70 MB/s
SHA-1 @ 8K: ~480 MB/s

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.
