Ayush Ranjan cf9d55bb6e Add device gofer connection.
Adds a gofer connection for /dev directory on the gofer when GPU functionality
is requested. This gofer connection is currently unused. The gofer client is
owned by the kernel, which injects the connection into the context. The gofer
connection is closed on container exit. S/R should be supported with this.
