$Id$
Currently its only save to link/unlink elements/pad when pipeline is in READY.
Belowe some thoughts. See http://bugzilla.gnome.org/show_bug.cgi?id=435487
for patches.

= thoughts =
* I don't think we need api for pads
* Should current api check for the state?
* do we want to swapp multiple elements at once
== events ==
* tee and adder need special treatment
* both would need to cache an accumulated segment
* tee
* would also cache tags
* when linkfunc is called, it can send out the segment and the tags
* when all pads got unlinked it could clear the segment
* adder
* when linkfunc gets called it sends a seek-event
= ideas =
== dynlinkpoint ==
* use cases
* its ment to be used with one side disconnected to allow to connect elements
at runtime
* it can be used in a pipeline to remove/insert elements at runtime
* element with 1 source- and 1 sinkpad
* when both connected it passes data thru
* if src is not connected it drops received buffers
* if sink is not conected
* it does not push
* it creates silence on pull
* events
* it caches events
* down: newsegment, tags, buffersize
* up: seek (needs to be modified)
* when other-pad get connected it pushes events depending on direction
