- The clock_wait now returns the difference between requested time and unlock time.

Browse source 
Original commit message from CVS:
- The clock_wait now returns the difference between requested time and
unlock time.
- Misc defines like GST_SECOND in gstclock.h
- remove pre/post in gstelement.c until fixed.
- added release_locks to gstelement so that the element can unlock itself
- added some more predefined events.
- added folowing functions to gstpad:
- convert function: get the relation between formats on this pad
- query function: get stats about the pad (position/total/latency)
- internal connect function: find out how this pad connects to other
pad internally to the element.
- generic pad_dispatcher.
- removed the last bits of pullregion
- use release_locks on the queue.
- added some events to queue
- make gstthread use the new release_locks function
- make the scheduler use the new clock_wait functions
- added events to fakesink
- added query functions to filesrc
- swap type and offset in the bytestream seek API to match fseek
- added some event handling in bytestream.
