Detailed Description

Implementation of KeymasterContext that proxies to another implementation.

Because AndroidKeymaster wraps a KeymasterContext and puts it into a unique pointer, it doesn't let the implementer manage the lifetime of the KeymasterContext implementation. This proxy breaks that relationship, and allows the lifetimes to be distinct as long as the KeymasterContext instance outlives the AndroidKeymaster instance.
