Add the libGenCEC library. It was designed to act as an interface between
the generic CEC kernel API and userspace applications. It provides a
simple interface for applications and an example application that can
be used to test the CEC functionality.

I agree that the best solution is to have a generic dmabuf allocator
but no only for secure use cases.
If we create a memory allocator dedicated to security it means that
userland will be responsible to use it or not depending of the context
which may change while the pipeline/graph is already run
