Wim Taymans 030ff93e82 docs/design/part-seeking.txt: Some small additions. 
Original commit message from CVS:
* docs/design/part-seeking.txt:
Some small additions.

* gst/base/gstbasesink.c: (gst_base_sink_handle_object),
(gst_base_sink_get_times), (gst_base_sink_do_sync),
(gst_base_sink_activate_push), (gst_base_sink_activate_pull):
* gst/base/gstbasesink.h:
discont values are gint64, handle the math correctly.

* gst/base/gstbasesrc.c: (gst_base_src_loop):
Make the basesrc report error if the source pad is not linked.

* gst/gstqueue.c: (gst_queue_link_src), (gst_queue_chain),
(gst_queue_loop), (gst_queue_handle_src_query),
(gst_queue_src_activate_push):
Make queue collect data even if the srcpad is not linked.
Start pushing out data as soon as it is linked.

* gst/gstutils.c: (gst_element_unlink), (gst_flow_get_name):
* gst/gstutils.h:
Added gst_flow_get_name() to ease error reporting.

Base classes
------------

GstBaseSink
 
  Base class for sink elements.

  - one sinkpad
  - handles state changes
  - does flushing
  - preroll with optional preview
  - pull/push mode
  - EOS handling

  FIXME: not much point making it operate in pull mode as a generic
  base class I guess... 

GstBaseTransform

  Base class for simple tranform filters

  - one sinkpad and one srcpad
  - possible formats on sink and source pad implemented
    with custom transform_caps function. By default uses 
    same format on sink and source.
  - handles state changes
  - does flushing
  - push mode
  - pull mode if transform can operate on arbitrary data

GstBaseSrc

  Base class for getrange based source elements

  - one sinkpad
  - handles state changes
  - pull/push mode
  - handles seeking/query

GstPushSrc

  Base class for push based source elements
