+/**
+ * Static wrapper for JNI functions that are needed for using a Java private key in the C++ OpenSSL

[bulach, 2014/02/14 10:45:29]

see above, I think we can have the @CalledByNative in the interface, then have
the key exposing its "@CalledByNative getKeyStore()", and then in the following
.cc file we just do something like:
  Java_AndroidKeyStore_getRSAKeyModules(....,
Java_AndroidPrivateKey_getKeyStore());

Done.
