6432	Asio needs to respect OPENSSL_NO_ENGINE preprocessor	calebmei@…	chris_kohlhoff	"OpenSSL on some platform might have open SSL with preprocessor OPENSSL_NO_ENGINE. Specifically this is for Android.

In such event, in
    boost/asio/ssl/detail/openssl_types.hpp
should not include,
    #include <openssl/engine.h>
And have to provide a default implementation for,
    static void ENGINE_cleanup(void) {};
So that boost asio can call this function later on.

Here's  the fix I did, please let me know if I should commit it back to the latest boost community."	Bugs	closed	To Be Determined	asio	Boost 1.48.0	Problem	fixed
