Windows: Runtime RDR Trace Toggle
Modify the IOCTL_AFS_CONFIG_LIBRARY_TRACE DeviceIoControl message
to pass an AFSDebugTraceConfigCB which is used to toggle the value
of the Library's AFSDebugTraceFnc pointer. When the trace log is
enabled, the AFSDbgLogMsg parameter is non-NULL and when the log is
disabled, the parameter is NULL.
