  Modified files:
    sys/kern             kern_descrip.c uipc_syscalls.c 
  Log:
  Do some minor Giant pushdown made possible by copyin, fget, fdrop,
  malloc and mbuf allocation all not requiring Giant.
  
  1) ostat, fstat and nfstat don't need Giant until they call fo_stat.
  2) accept can copyin the address length without grabbing Giant.
  3) sendit doesn't need Giant, so don't bother grabbing it until kern_sendit.
  4) move Giant grabbing from each indivitual recv* syscall to recvit.
