Only use -Wshadow with GCC > 4.6.0. Prior to 4.6.0, -Wshadow would cause GCC to warn when variables shadowed global functions. Since libc defines a number of functions with common names, this is a problem. Also, without this change, we'll keep breaking on older versions of GCC because we won't be testing with them. OpenBSD, specifically is reported to have a problem: https://boringssl-review.googlesource.com/#/c/2900/ (Note the test should really be >= 4.6.0, but CMake doesn't have a VERSION_GREATEROREQUAL.)

Add visibility rules. This change marks public symbols as dynamically exported. This means that it becomes viable to build a shared library of libcrypto and libssl with -fvisibility=hidden. On Windows, one not only needs to mark functions for export in a component, but also for import when using them from a different component. Because of this we have to build with |BORINGSSL_IMPLEMENTATION| defined when building the code. Other components, when including our headers, won't have that defined and then the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines in base.h In the asm code, symbols are now hidden by default and those that need to be exported are wrapped by a C function. In order to support Chromium, a couple of libssl functions were moved to ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

aarch64 support. This is an initial cut at aarch64 support. I have only qemu to test it however—hopefully hardware will be coming soon. This also affects 32-bit ARM in that aarch64 chips can run 32-bit code and we would like to be able to take advantage of the crypto operations even in 32-bit mode. AES and GHASH should Just Work in this case: the -armx.pl files can be built for either 32- or 64-bit mode based on the flavour argument given to the Perl script. SHA-1 and SHA-256 don't work like this however because they've never support for multiple implementations, thus BoringSSL built for 32-bit won't use the SHA instructions on an aarch64 chip. No dedicated ChaCha20 or Poly1305 support yet.

Make build work on OS X with older cmake versions. `uname -p` is still i386 on OS X for some reason, which causes cmake 2.8 to set CMAKE_SYSTEM_PROCESSOR to i386, making the build think it's doing a 32-bit build. However, since the system is almost completely 64-bit these days, clang defaults to producing 64-bit object files unless told otherwise. As a result, the produced .o files are all 64-bit except for the .o files from assembly, and then linking fails. Fix this by forcing ARCH to 64-bit on OS X. This matches the default behavior of cmake 3.0, where CMAKE_SYSTEM_PROCESSOR is x86_64.
