    LWP: Avoid casting functions to void pointer
    
    Commit 09aba81c50cb (Cast LWP event functions to void pointer) fixed a
    compiler warning when building binaries with LWP threaded, but did so in
    a way that appeased the compiler but did not address the underlying
    undefined behavior.
    
    The ISO C standard states "a pointer to any object type may be converted
    to a pointer to void and back again; the result shall compare equal to
    the original pointer", but since a function is not defined as an object,
    the conversion of function pointer to a void pointer is undefined.
    
    Fix this by creating dummy integer globals to be used as the event ids
    for the few places function pointers are used for event ids.  The values
    of the dummy variables are set but are never read.
