    Make globals use sharedCAF
    
    The use of globals is quite painful when multiple rts are loaded, e.g.
    when plugins are loaded, which bring in a second rts. The sharedCAF
    appraoch was employed for the FastStringTable; I've taken the libery
    to extend this to the other globals I could find.
