This is either a rewrite or a large bugfix to the queue element, whatever you prefer to call it.

Original commit message from CVS:
This is either a rewrite or a large bugfix to the queue element, whatever
you prefer to call it.

* upstream event forwarding now works. This should fix Julien's issues.
* this queue allows setting a min. treshold size and a max. limit size
in bytes, buffers and time before the queue allows the next element
to pull data or the previous element to push data into it. This is
very interesting for network-related buffering. Also includes signals
et all for the end user application.
* Events are no longer part of the queue's "size", they're essentially
seen as "void data". they have no size or time associated with them
anyway, so this shouldn't really sound weird.
