Add a new event flag for sticky events so that multiple events of that type can
be stored on a pad at the same time. Change the _get_sticky_event() function to
loop over the multiple events of a type.
Change the foreach function to make it possible to removed and modify the sticky
events on a pad.
Use an variable size array now to store the events. This could later be
optimized some more.
When the foreach function told us to remove the buffer from the list, decrease
the length of the array or else we might read past the last item in the array.
In 0.10, this can be done with a one-liner by using GST_BUFFER_DATA/SIZE with
put_data. A 0.11 user has to resort to gst_buffer_map, which is less convenient
and might require a memcpy internally.
API: gst_byte_writer_put_buffer()
Rewrite sticky events, trying to make it a bit more simple.
When sticky events are pushed on a srcpad, store them in the sticky event
array and mark the event with received = FALSE.
When the sticky event is successfully sent to the peer pad, make
received = TRUE.
Keep a PENDING_EVENTS pad flag that is set when one of the events is in
the received = FALSE state for some reason.
when activating a sinkpad, mark all events received = FALSE on the peer
srcpad.
When pushing a buffer, check the PENDING_EVENTS flag and if it is set, push all
events to the peer pad first.
Fixes compiler warnings on OSX:

const gpointer is not the same as gconstpointer or const void *.

Add _full variants of the pad function setters that take a destroy notify.
Make some macros that make the old method name pass NULL to this new
function.
Add the pad mode to the activate function so that we can reuse the same function
for all activation modes. This makes the core logic smaller and allows for some
elements to make their activation code easier. It would allow us to add more
scheduling modes later without having to add more activate functions.
Turns some boolean arguments in the scheduling query to flags, which are easier
to extend and makes the code easier to read.
Make extra methods for configuring and querying the supported scheduling modes.
This should make it easier to add new modes later.
Add a new pad flag NEED_PARENT that ensures that the parent of a pad is
reffed and not NULL when the event, query and internal links functions
are called.
When a pad is added to an element automatically make sure the NEED_PARENT flag
is enabled.
fix the proxy functions for query_accept_caps and query_caps to use the pad
forward helper functions which correctly forwards on the internally linked pads.
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.
Make that implizit with attaching/detaching controlsources. This is a lot easier
and has less invalid state (controlled property without control source).
