Wim Taymans 347505bcb9 - major API breakage (one of the last, I promise...) 
Original commit message from CVS:
- major API breakage (one of the last, I promise...)
- GST_PAD_QUERY -> GST_QUERY
- GstPadQuery -> GstQuery
- Move query definitions to gstquery.h to allow for future dynamic
query types.
- remove _pad_handles_* in favour of extra format/event functions to
make the same checks.
- fix elements
- Implemented missing query/event/formats functions in gstelement
