libs/gst/base/gstbasetransform.c: Implement a checkgetrange function instead of relying on the default core behaviour...

Browse source 
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c: (gst_base_transform_init),
(gst_base_transform_check_get_range):
Implement a checkgetrange function instead of relying on the default
core behaviour that assumes we can operate in pull mode if we have a
getrange function. First step at fixing #385084.
