    crash detect: use StopDisplay().
    
    This patch solves a benign bug: on server crash the display is removed
    but the server exit code is ignored.  Proposed solution: substitute
    RemoveDisplay() by StopDisplay() thus enabling the wait for child exit
    synchronism.

    Fix missing linking dependency on -ldl.
    
    Recent versions of GCC ship with a linker that doesn't add the deps
    of the DSOs to the linking process. This behavior is also found in
    GNU gold. This change fixes building with those linkers.
