Anastasia Klimchuk c845e64b4f opaque_master: Add shutdown function in opaque_master struct
With this, register_opaque_master can take care of register_shutdown
as well, and every opaque master only needs to call
register_opaque_master instead of calling both register_opaque_master
and register_shutdown.

Next patches in the chain convert opaque masters to use new API.
