    Rework si:type:value code to remove need for shadowed namelen variable
    
    Fixes gcc warning:
    xhost.c:453:6: warning: declaration of ‘namelen’ shadows a previous local
    xhost.c:339:9: warning: shadowed declaration is here
    
    Also removes unnecessary malloc and memcpy by just using the string
    pointers we already have, since XAddHost & XRemoveHost will copy the
    specified length of text from the strings to the Xlib request buffer
    before returning, not relying on nil termination.
