MediaCas: combine openSession methods

2017-04-11T19:22:23+00:00

Combine the two openSession methods into one that doesn't take any
arguments. This gives the client more flexibility on creating
sessions efficiently. They can better decide whether to share one
session for multiple streams, or create one session per stream.

keys in the clear in ECMs. It initializes from a test asset string
with a valid id. It outputs to clear buffers.
