Joachim Bauch fec2c6d7eb Prevent potential double-free if srtp_create fails.
If srtp_create fails while adding streams, it deallocates the session
but doesn't clear the passed pointer which then could lead to a
double-free in the SrtpSession dtor.

The CL also adds locking for libsrtp initialization / shutdown.
