Checks synchronously the file on disk, to know whether the file is externally
modified, or has been deleted, and whether the file is read-only.
#GtkSourceFile doesn't create a #GFileMonitor to track those properties, so
this function needs to be called instead. Creating lots of #GFileMonitor's
would take lots of resources.
Since this function is synchronous, it is advised to call it only on local
files. See gtk_source_file_is_local().
