Original commit message from CVS:
* gst/elements/gstfilesink.c: (gst_file_sink_do_seek),
(gst_file_sink_get_current_offset):
Use fseeko() and ftello() if available. When falling back on
lseek() to get the current offset, fflush() first to make sure
everything is up-to-date and we get the right offset.
