e6febb5bc1 basesink: Document the interaction between unlock() and wait_preroll()
This was totally non-obvious, the kind of big problem is that subclasses must
be able to unblock their streaming thread and continue exactly where they left off
on unpause!

812d4976f0 fakesink: Add property to not drop out-of-segment buffers
Implement handling in basesink to not unconditionally discard
out-of-segment buffers and expose it as a new property on fakesink
(not unconditionally in all basesink based sinks).

The property defaults to FALSE.

66b6d355e4 basesink: rename argument of PREROLL_{COND,LOCK} macros
They take a GstBaseSink instance as argument at not a GstPad. Rename the
argument to 'obj' which is not miss leading and in line with
GST_BASE_SINK_PAD(obj).

d8413cd0a2 basesink: add simple rate control
Add a max-bitrate property that will slightly delay rendering of buffers if it
would exceed the maximum defined bitrate. This can be used to do
rate control on network sinks, for example.

API: GstBaseSink::max-bitrate
API: gst_base_sink_set_max_bitrate()

927f261b1c basesink: wait_eos() -> wait()
Rename gst_base_sink_wait_eos() to gst_base_sink_wait() to avoid confusion and
introspection problems with the ::wait_eos vmethod. Also this method can be used
to wait for other things than EOS. Update the docs a little.

602bd29960 basesink: add prepare method
Add a prepare method that is called before sync happens. The purpose of this
method is to prepare the rendering of the giving buffer so that the following
render() call after sync is a quick as possible.

43abf99a8a caps: avoid using in-place oprations
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.

0e38f0dad0 basesink: clean up event handling
Add new wait_eos vmethod to wait for the eos timeout before posting the EOS
message on the bus.
Add default event handler. Move the default event actions in there. Call the
event vmethod from the pad event handler. Subclasses are now supposed to chain
up to the parent event handler or unref the event and do their own thing.
Avoid passing unused parameters to functions.
