Refactored the fpga and testbench so the RVVI can be synthesized cleanly and simulated without any major code changes.
...
Adds three new configuration parameters to control enabling the RVVI packetizer and how much latency should exist between packets and the initial startup delay.

Successfully added RVVIStall for back pressure to slow down the pipeline if the ethernet or host computer running imperasDV can't keep up.

This version passes the regression test and solves issue #200 . wfi's implemenation is changed so that wfi does not take an interrupt in the Memory stage. Instead it advances to the Writeback stage then traps.

MDU and hazard unit now also parameterized. Based on Lim's work. Again I want to clarify this their work. Not mine. I'm just doing this because the merge had an issue.
