        * include/jvm.h: (_Jv_GetNbArgs) added
        (_Jv_GetSafeArg) added
        (_Jv_SetArgs) added
        * prims.cc: (_Jv_GetNbArgs) implemented
        (_Jv_GetSafeArg) implemented
        (_Jv_SetArgs) implemented
        (_Jv_RunMain) use _Jv_SetArgs() instead of explicitly
        setting _Jv_argc and _Jv_argv
        * posix.cc: (_Jv_ThisExecutable) use _Jv_GetSafeArg()
        instead of _Jv_argv
        * java/lang/natRuntime.cc: (insertSystemProperties) use
        _Jv_GetSafeArg() instead of _Jv_argv
