    linux emu - peripheral changes
    
    * These are peripheral changes to prepare for the import of the updated
      linuxulator:
    
    * hooks (eventhandler) for process creation and process exit.
    
    * splitting up of sys_kevent into sys_kevent + kern_kevent, including
      generic copyiin and copyout functions.
      Obtained-from: FreeBSD
    
    * adding a p_textnch to store the namecache handle for the .text file.
    
    * minor changes to sysv_sem and sysv_shm to support linux-specific
      magic.
    
    * bring in casuword (compare and set userland word)
      Obtained-from: FreeBSD
    
    * add a hook for userret from syscall2
      Inspired-by: NetBSD
