03163f3a11 Remove |CRYPTO_add|.
It's no longer needed after the conversion to |CRYPTO_refcount_t|.

6f2e733bab Add infrastructure for reference counts.
OpenSSL has traditionally done reference counting with |int|s and the
|CRYPTO_add| function. Unless a special callback is installed (rare),
this is implemented by doing the reference count operations under a
lock.

This change adds infrastructure for handling reference counts and uses
atomic operations when C11 support is available.

65a7e9442c Support Trusty, an embedded platform.
Trusty doesn't have setjmp.h and nor does it have threads.

f0df86a1f6 Fix standalone build on Mac.
CRYPTO_MUTEX was the wrong size. Fortunately, Apple was kind enough to define
pthread_rwlock_t unconditionally, so we can be spared fighting with feature
macros. Some of the stdlib.h removals were wrong and clang is pick about
multiply-defined typedefs. Apparently that's a C11 thing?

df1f5e796c crypto: add mutexes.
Prior to this, BoringSSL was using OpenSSL's technique of having users
register a callback for locking operation. This change adds native mutex
support.

Since mutexes often need to be in objects that are exposed via public
headers, the non-static mutexes are defined in thread.h. However, on
Windows we don't want to #include windows.h for CRITICAL_SECTION and, on
Linux, pthread.h doesn't define pthread_rwlock_t unless the feature
flags are set correctly—something that we can't control in general
for public header files. Thus, on both platforms, the mutex is defined
as a uint8_t[] of equal or greater size and we depend on static asserts
to ensure that everything works out ok.

33672736b7 Get rid of the THREADID stuff.
Now that ERR is using thread-local storage, there's very little that the
THREADID code is doing and it can be turned into stub functions.

8056343a58 Fix CRYPTO_add_lock documentation.
It's not actually CRYPTO_add_locked, despite the name. I guess they just needed
a name that didn't clash with CRYPTO_add.

ab2a8e03d9 Fix duplicate lock IDs & simplify lock ID maintenance.
* Eliminate the possibility of multiple lock IDs having the same
  value (CRYPTO_LOCK_FIPS2 and CRYPTO_LOCK_OBJ were both 40 prior to
  this commit).
* Remove unused lock IDs.
* Automatically guarantee that lock IDs and lock names stay in sync.

533cbee57e Also export some deprecated functions.
I didn't mark these functions as OPENSSL_EXPORT in the first place
because I was hoping that they wouldn't be needed. However, WebRTC and
libjingle are using them.

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.

4c921e1bbc Move public headers to include/openssl/
Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.

This doesn't work on Windows.

This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
