Fixed auto configure bugs which didn't allow Fixed CSR Addresses or Fixed Vectors to be set using the auto configure information.
Fixed display of address and vectors to indicate that the assigned address and/or vector is in the floating set.
Added extended definitions to the auto configure table to reflect all known potential static and floating and static addresses as of VMS V5.5-2
Changed the name of the VAX 11/780 console floppy device name to RXC from RX (which collides with a Unibus name for the RX11).
scp.c,scp.h - Gave priority to a command message handler to determine what values result in displayed messages and exported run_cmd_message for use by simulators which add simulator specific BOOT commands which leverage the run_cmd logic and should also leverage the run_cmd_message for message display
VAX/vax610_sysdev.c, vax730_sys.c, vax750_cmi.c, vax780_sbi.c - Added BOOT command message dispatch to run_cmd_message for simulators which perform preprocessing on BOOT activities but otherwise then dispatch to run_cmd.
