This commit introduces dozens of changes to make the 3B2-700 simulator fully functional and ready for wider use. In addition to 3B2-700 availability, this commit includes a tremendous amount of refactoring of the 3B2-400 and common code to make the project structure easier to maintain and reason about. One final important change: ROM files are no longer included in the source code. 3B2 ROM images must be obtained separately and loaded into the simulator before boot. Changes: - The 3b2 target has been aliased to 3b2-400 - The formerly named 3b2-600 project has become 3b2-700 - SCSI QIC tape support has been added to sim_scsi.c - Header files have been reworked to reduce complexity of includes - Common code has been consolidated - Timer code has been unified
