c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.

9ef1346b1f context: use context on buffers instead of caps
Put the srcpad context on buffers instead of caps. This allows us to associate
all the relevant info contained in events with a buffer.

9136abf623 pad: use the context to store sticky events

bc9cffda90 pad: more sticky events work
Copy the sticky events from the srcpad to the sinkpad when linking pads. Set the
STICKY_PENDING flag to make sure that the sticky events are dispatched before
pushing the next buffer to the element.

2243adffa1 event: add sticky flags to events
Add the sticky flag to events and a sticky index.
Keep sticky events in an array on each pad.
Remove GST_EVENT_SRC(), it is causing refcycles with sticky events, was not used
and is not very interesting anyway.

6ab7e6c15d Remove pad_alloc, this can now be done better
Remove pad_alloc and all references. This can now be done more efficiently and
more flexible with the ALLOCATION query and the bufferpool objects. There is no
reverse negotiation yet but that will be done with an event later.

b2ab72b916 pad: remove get_caps_reffed variants
Make the _get_caps functions behave like the _get_caps_reffed variants and
remove the _reffed variants. This means that _get_caps doesn't return a writable
caps anymore and an explicit _make_writable() is needed before modifying the
caps.

d7f59ca0c4 pad: Deprecate GST_FLOW_IS_FATAL() and GST_FLOW_IS_SUCCESS()
The problem with both macros is, that they suggest something that isn't true.
If GST_FLOW_IS_FATAL is true, there could still be a problem for many elements
and they should stop what they're currently doing and return that value
upstream (e.g. not-linked in a parser). If GST_FLOW_IS_SUCCESS is false, it
could still be that this is "ok" for the element (e.g. not-linked for a demuxer
on a few of its pads but not all).

It's better to not have these "convenience" macros but instead let people
*think* about the handling of different flow returns, that makes sense for
their element. And we should document the expected handling of flow returns for
different classes of elements in the plugin writer's guide.

Fixes bug #628014.

fcc5d783df pad: add variants of gst_pad_get_caps() that don't copy caps. Fixes #590941
