AMBA AXI4 bus functional model and agent

Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1

AXI4 master and slave agents with configurable outstanding depth, ID ordering, randomized ready/valid delays, burst types and a backing memory model for the slave.

Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
