We enable multiple engines by: * getting rid of the globals that point to the one available HW and one available SW engine * adding a submit_tasks() entry point for the SW engine so that it is treated like any other engine allowing us to just call submit_tasks() to the assigned engine for the opcode instead of checking what is supported * changing the definition of engine capabilities from "HW accelerated" to simply "supported" * during init, use a global (g_engines_opc) that contains engines and is indexed by opcode so we know what the best engine is for each op code * future patches will add RPC's to override engine priorities or specifically assign an opcode(s) to an engine.
