the attached patch is based on unified-patch 18-9.
i've done this via xkb's XkbGetIndicatorState function
if the states indicate that numlock is on then do a
rdp_send_input witch the numlock scancode ...

i call the new sync_lockkeys function from within 
the ui_process_events function - not the perfect place.
(sync_lockkeys must be called only once and ui_process_events
is called frequently - anyone knows a better place?)


best regards,
Norbert
