Andy Wingo e040bb2dbe gst/gstelement.h (GstState): Renamed from GstElementState, changed to be a normal enum instead of flags.
Original commit message from CVS:
2005-09-02  Andy Wingo  <wingo@pobox.com>

* gst/gstelement.h (GstState): Renamed from GstElementState,
changed to be a normal enum instead of flags.
(GstStateChangeReturn): Renamed from GstElementStateReturn, names
munged to be GST_STATE_CHANGE_*.
(GST_STATE_CHANGE): Renamed from GST_STATE_TRANSITION, updated to
work with the new state representation.
(GstStateChange): New enumeration of possible state transitions.
Replaces GST_STATE_FOO_TO_BAR with GST_STATE_CHANGE_FOO_TO_BAR.
(GstElementClass::change_state): Pass the GstStateChange along as
an argument. Helps language bindings, so they don't have to use
tricky lock-needing macros like GST_STATE_CHANGE ().

* scripts/update-states (file): New script. Run it on a file to
update it for state naming and API changes. Updates files in
place.

* All files updated for the new API.
