  Modified files:
    sys/compat/linux     linux_ipc.c 
    sys/sys              syscallsubr.h 
    sys/kern             sysv_shm.c 
  Log:
  Change the semantics of sysv shm emulation to take a additional
  argument to the functions shm{at,ctl}1 and shm_find_segment_by_shmid{x}.
  The BSD semantics didn't allow the usage of shared segment after
  being marked for removal through IPC_RMID.
  
  The patch involves the following functions:
    - shmat
    - shmctl
    - shm_find_segment_by_shmid
    - shm_find_segment_by_shmidx
    - linux_shmat
    - linux_shmctl
