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 support for building with the Android NDK. Previously I've been using the Linaro toolchains and just building static binaries. However, the Linaro toolchains have a broken pthread_rwlock_wrlock—it does nothing and then unlocking corrupts the lock. Building with the Android NDK avoids this. These build instructions depend on https://github.com/taka-no-me/android-cmake which people will need to clone into util/ if they want to use the Android NDK.

Generate error data at build time. This avoids cluttering up the diff and making merge conflicts a pain. It does, however, mean we need to generate err_data.c ahead of time in Chromium and likely other downstream builds. It also adds a build dependency on Go.

Add infrastructure for reference counts. OpenSSL has traditionally done reference counting with |int|s and the |CRYPTO_add| function.

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.

Add support for building with the Android NDK. Previously I've been using the Linaro toolchains and just building static binaries. However, the Linaro toolchains have a broken pthread_rwlock_wrlock—it does nothing and then unlocking corrupts the lock. Building with the Android NDK avoids this. These build instructions depend on https://github.com/taka-no-me/android-cmake which people will need to clone into util/ if they want to use the Android NDK.

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.

Add a run_tests target to run all tests. It's very annoying having to remember the right incant every time I want to switch around between my build, build-release, build-asan, etc., output directories. Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and Ninja 1.5+). This combination gives a USES_TERMINAL flag to add_custom_target which uses Ninja's "console" pool, otherwise the output buffering gets in the way. Ubuntu LTS is still on an older CMake, so do a version check in the meantime. CMake also has its own test mechanism (CTest), but this doesn't use it. It seems to prefer knowing what all the tests are and then tries to do its own output management and parallelizing and such. We already have our own runners. all_tests.go could actually be converted tidily, but generate_build_files.py also needs to read it, and runner.go has very specific needs. Naming the target ninja -C build test would be nice, but CTest squats that name and CMake grumps when you use a reserved name, so I've gone with run_tests.
