Original commit message from CVS:
- added playondemand plugin by Leif Morgan Johnson <lmjohns3@eos.ncsu.edu>
- some fixes to int2float
- aplied a patch from wrobell <wrobell@ite.pl> that is a first attempt at
making automake 1.5 happy (gst now requires automake1.5). It's still not
perfect but it builds.
- Made the schedulers plugable. The default scheduler now lives inside a
plugin.
- Added a new mpeg1/2 parser/demuxer.
- Fixed some compiler warnings in the core libs.
- substantial work to GstThread (hopefully less race conditions). simplified
the code in GstThread a bit. A state change can now also happen in the
thread context.
- reworked the state semantics of a bin. it'll now automatically get the
highest state of its children.
- the autoplugger now nests the threads so that a state change failure of
one thread doesn't make its upstream thread lock.
- GstQueue refuses to go to PLAYING if the sinkpad is not connected. This
way the queue will not wedge in the _get lock.
- GstQueue unlocks its mutexes when going to PAUSED.
- make sure that when all elements in a bin/thread go to PAUSED, the bin
is set to PAUSED too.
- make a parent bin wait for its children to PAUSE before ending the
iteration with FALSE (EOS)
- Some changes to GstPlay to deal with EOS.
- aplied the latest patch from Zeenix to gstrtp.

end result: GstPlay doesn't crash on EOS and the pipeline is now shut down
properly.
