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.
