  Modified files:
    sys/kern             init_main.c kern_resource.c kern_synch.c 
                         subr_trap.c 
    sys/sys              proc.h resourcevar.h 
  Log:
  - Move p_cpulimit to struct proc from struct plimit and protect it with
    sched_lock.  This means that we no longer access p_limit in mi_switch()
    and the p_limit pointer can be protected by the proc lock.
  - Remove PRS_ZOMBIE check from CPU limit test in mi_switch().  PRS_ZOMBIE
    processes don't call mi_switch(), and even if they did there is no longer
    the danger of p_limit being NULL (which is what the original zombie check
    was added for).
  - When we bump the current processes soft CPU limit in ast(), just bump the
    private p_cpulimit instead of the shared rlimit.  This fixes an XXX for
    some value of fix.  There is still a (probably benign) bug in that this
    code doesn't check that the new soft limit exceeds the hard limit.
