    Don't register a thread-ID callback on Windows.

    pthread_t on MinGW32 is a struct, and long is not large enough to hold the void*
    within.

    OpenSSL documentation states: If the application does not register such a callback
    using CRYPTO_THREADID_set_callback(), then a default implementation is used - on
    Windows and BeOS this uses the system's default thread identifying APIs

    So not setting this callback at all will be safe.

    With OpenSSL initialized to be made thread-safe, we don't have to serialize
    access to the OpenSSL functions anymore.

    Some other things were protected here by the cft_system locking:

    - the ServerConnectionState *conn

    This structure is initialized in the main thread, and then passed to the
    thread handler, which takes exclusive ownership. No access to this object
    from other threads is possible or allowed.

    - malloc calls

    Those are implicily threadsafe on all supported platforms today

    Initialize OpenSSL with callback functions for threadlocking.

    This makes OpenSSL threadsafe, and allows us to remove locking around the
    calls to the RSA encryption functions in cf-serverd's AuthenticationDialogue.
    Implements #2678

    Note: the functions used - as well as most other functions used from
    OpenSSL - are marked as deprecated on Mac OSX 10.7 and later.
    Compiler warnings explicitly disabled. Functions documented in OpenSSL
    documentation (http://www.openssl.org/docs/crypto/threads.html) to replace
    some of these functions (such as CRYPTO_THREADID_set_callback) are not
    available. This implementation follows the example provided on
    http://www.opensource.apple.com/source/OpenSSL/OpenSSL-10/openssl/crypto/threads/mttest.c

    Silence deprecated warnings when compiling on Mac OSX.

    Majority of functions in /usr/include/openssl/crypto.h are marked as
    deprecated for Mac OSX 10.7 and later. Silence warnings.
