Benjamin Otte 3a897e2f30 rewritten pipeline parsing lands. Have fun breaking it.
Original commit message from CVS:
rewritten pipeline parsing lands. Have fun breaking it.
regressions:
- No support for filtered links. If anybody needs this, please contact me and I'll add it as fast as possible.

improvements:
- The pipeline building actually works as expected.
- syntax compatible nearly everywhere but more flexible
- better property parsing (you can now set enums by name or nick)
- uses locked_state to allow for delayed pads
- can connect video pipelines without the need for queues
- allows properties on bins
- does not return a bin, but an element.

You may want to read docs/random/company/gstparse to learn how it works.
