All meterpreter Clients are created equal, and as such they all
include the PacketDispatcher mixin and call its init methods when
a passive dispatcher is needed. However, since tunneling protocols
have different requirements for implementation, the methods which
provide protocol-specific functionality need to be mixed into the
Client before it attempts to initialize the dispatcher.
Provide a dispatch_ext option in the has passed to the client on
init from the session handler which is an Array containing mixin
references which are sent to :extend calls in the :init_meterpreter
method just prior to calling :initialize_passive_dispatcher.
Each handler implementation can thus push chains of mixins to the
client in order to provide middleware specific to the tunnel. Down
the road, this should permit stacking C2 encapsulations or tunnel
protocols/permutators to create unique session transports on the
fly.
