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.

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.

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

* 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.

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.

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.

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.
