    kernel: Add three new commands to fctnl
    
    This commit adds the following new commands to fcntl():
      F_DUP2FD         - non-portable functional equivalent of dup2(fd, arg)
      F_DUPFD_CLOEXEC  - A version of F_DUPFD that sets the close-on-exec
                         on the new file descriptor
      F_DUP2FD_CLOEXEC - A version of F_DUP2FD that sets the close-on-exec
                         on the new file descriptor.  It is non-portable
    
    It also adds a missing break in a case statement for F_GETOWN in
    sys_fnctl(), spotted by dillon.
