libs/gst/base/gsttypefindhelper.c: If we are provided with the size, we should implement

Browse source 
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (helper_find_get_length),
(gst_type_find_helper_get_range):
If we are provided with the size, we should implement
GstTypeFind::get_length, so that typefind functions who
want to can actually peek at the middle of a file.
