2e38008558 Define _HAS_EXCEPTIONS=0 to avoid MSVC C4530 warning.
Avoid "warning C4530: C++ exception handler used, but unwind semantics
are not enabled. Specify /EHsc" when compiling MSVC's <xlocale> by
disabling the exception code in MSVC's STL using _HAS_EXCEPTIONS=0.

507c1eec51 Honor the standard BUILD_SHARED_LIBS cmake variable.
The variable switches the default type for add_library from STATIC to SHARED.
We can condition additional stuff on that for convenience. (tabtest still
doesn't build.)

BoringSSL as any kind of stable system shared library is still very much
unsupported, but this is probably handy for making sure we don't forget all
those pesky OPENSSL_EXPORTs.

9a9a193388 Build with -fvisibility=hidden.
This matches the Chromium build, in both static and components builds. (Also
happens to sort out an undocumented requirement of the standalone shared
library build.)

1d75c8be73 Improve compatibility with CMake 3.0 and later
CMake 3.0 changed the identifier for Apple-supplied Clang to
AppleClang.

CMake 3.1 changed the behavior of variable expansion in quoted
strings and complains with warning CMP0054 twice without these
changes.

07100c6e69 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.)

3e6526575a 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.

f9a40b2ce5 Remove -std=c89 from compiler command line.
We aren't targeting pure C89 any longer and it also upsets GCC on
AArch64 because asm() isn't part of C89.

af7e74ba9f Remove variable shadowing.
Bruce Dawson pointed out that the shadowing of |ret| in |s3_srvr.c|
looked dodgy. It was actually deliberate (we don't want to reset the
default value of the function's |ret| variable with a successful return
from the callback) but it does look dodgy.

This change adds -Wshadow to ban variable shadowing and fixes all
current instances.

deb5284138 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.

eb7d2ed1fe 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.

1d8adf18d2 Fix CPU architecture detection on BSDs.
CMake calls "uname" in order to detect the CPU architecture,
so $(CMAKE_SYSTEM_PROCESSOR) varies from platform to platform.

This changes adds support for "i386" and "amd64" values, which
are used by BSDs for the x86 family of CPUs.
