They're small, but they should be read-only. This slightly changes public API
and affects downstream WebRTC code.

The old ones inverted their return value. Add SSL_(CTX_)set_srtp_profiles which
return success/failure correctly and deprecate the old functions. Also align
srtp.h with the new style since it's very short.

When this rolls through, we can move WebRTC over to the new ones.

Switch all of SRTP code to the standard return value convention with two
exceptions. Unfortunately, OpenSSL exposed API with the wrong error code. Keep
the public API flipped and document.

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.
