    Address more scanbuild/gcc/clang warnings
    
    gdevkrnlsclass.c Change a while...do into a do...while to see if it
    pacifies a 'dereference of NULL pointer' in scanbuild
    
    gsparamx.c Incorrect return code could lead to an earlier error not
    being preserved. Fortunately this is currently only called by claptrap.
    
    gsptype1.c  remove unnecessary assignments
    gssprintf.c    "       "          "
    gstype2.c      "       "          "
    gstype42.c     "       "          "
    gxfill.c       "       "          "
    
    gsptype2.c rejig the code to avoid setting a return code that isn't used.
    Add a check on a return code that was missing.
    
    gxchar.c add return code checking
    gxcmap.c  "    "     "     "
