console code cleanup

Browse source 
console/console.c:
    the go parameter to unixBoot is never used, so get rid of it.
    just panic if we return from unixBoot since it's never supposed
    to happen.
    remove the MAX_CPUS parameter and the bootStrapImpure variable
    and just allocate memory as needed.  (Can in theory support many
    more CPUs.)
