Added logic to track OSD updates separately from internal view updates in the

Browse Source 
debugger. In order to get the OSD to update, a new function 
debug_view_flush_updates() must be called. Currently this is automatically
called before osd_wait_for_debugger(), and during the periodic updates while
executing. The OSD code may occasionally need to call it under other
circumstances (for example, the Windows code calls it explicitly while
tracking scrollbar thumbs to get live scrolling).
