MSVC doesn't like unary - on unsigned numbers. Also switch ssl3_read_n's
version to uintptr_t to match the write half. This gets us closer to clearing
through C4311 violations. (The remaining one is in asn1_add_error which can go
after verifying that most of asn1_mac.h is safe to drop.)

(We might want to reconsider enabling all of MSVC's warnings. Given the sorts
of warnings some of these are, I'm not sure MSVC's version of -Wall -Werror is

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.

`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.

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.
