92b4c8967b pad: don't use buffer caps for negotiation 
Don't use the buffer caps for negotiation anymore but use the CAPS events.
Make the _set_caps method produce the CAPS event, add some backward
compatibility code to trigger the setcaps functions on src and sinkpads.
Remove all negotiation code from the chain functions.
Don't use the GST_PAD_CAPS variable anymore to store the caps but retrieve the
caps from the sticky event array.

4372869e80 pad: implement more sticky events 
Remove the context again, adding an extra layer of refcounting and object
creation to manage an array is too complicated and inefficient. Use a simple
array again.
Also implement event updates when calling gst_pad_chain() and
gst_event_send_event() directly.

218bc52c7f info: avoid redefinition of symbols when debugging is off 
The refactoring of gst_debug_add_log_function() now causes build failure when
debug-logging is turned off. Just move it to the conditional part of the header.

f663c9770b pad: simplify some more

the context on the peer pad.

d3e0a37900 pad: improve context passing some more 
Pass the context downstream when it got updated.
Have two ways of informing downstream of events, do a full context update when
the CONTEXT_PENDING flag is set and simply forward the event otherwise.
Set the CONTENT_PENDING flag when linking pads.
We don't need to old context anymore when updating the context of a pad.

dc63e38219 caps: Merge structures when intersecting instead of appending them 
This prevents adding duplicates over and over again to the resulting
caps if they already describe the new intersection result.

While this changes intersection from O(n*m) to O(n^2*m), it results in
smaller caps, which in the end will decrease further processing times.

For example in an audioconvert ! audioconvert ! audioconvert pipeline,
when forwarding the downstream caps preference in basetransform
(see e26da72de25a91c3eaad9f7c8b2f53ba888a0394) this results in
16 instead of 191 caps structures.

581533cd00 pad: Drop renegotiate event if there is no getcaps function on a sink pad 
If there is no custom getcaps function on a sink pad, then changes in
downstream caps will never be propagated, so there is no point in trying to
renegotiate the capabilities.
