    bhyve: Replace many fprintf(stderr, ...) calls with EPRINTLN
    
    EPRINTLN handles newlines appropriately when stdout/stderr have been
    reused as the backend for a serial port.
    
    For bhyverun.c itself, the rule this attempts to follow is to use
    regular fprintf/perror/warn/err prior to init_pci() (which is when
    serial ports are configured) and to switch to EPRINTLN afterwards.
