This removes the crossfade-ratio property and replaces it with an
operator property. Currently this implements the following operators:
- SOURCE: Copy over the source and don't look at the destination
- OVER: Default blending of the source over the destination
- ADD: Like OVER but simply adding the alpha instead
See the example for how to implement crossfading with this.

The previous failure was a timeout which was due to the sending pipeline
pushing test buffer *before* the remote client was accepted. We would
therefore never get the buffer on the other side.
While the client socket would indeed appear as "connected", this doesn't
mean that the remote server side did "accept" it (which is where we then
add it to the list of remote parties to which data will be sent).
The problem isn't with the element implementation, but to the nature of
TCP 3-way handshake.
In order to make the test reliable, wait for the sink to have accepted
the remote client (by checking the number of handles) before sending out
test buffers.
rtsp_connection_send takes care of adding those already,
and some reverse proxies such as nginx will reject the request
altogether if the Authorization header is present twice,
even with the same value.

Add a source-info property that will read/write meta to the buffers
about RTP source information. The GstRTPSourceMeta can be used to
transport information about the origin of a buffer, e.g. the sources
that is included in a mixed audio buffer.
A new function gst_rtp_base_payload_allocate_output_buffer() is added
for payloaders to use to allocate the output RTP buffer with the correct
number of CSRCs according to the meta and fill it.
RTPSourceMeta does not make sense on RTP buffers since the information
is in the RTP header. So the payloader will strip the meta from the
output buffer.

Fixes the internal viewconvert to not scale buffers for output with the
following pipeline:
gltestsrc ! glimagesink
It also fixes overlay composition with a resized output with an OpenGL
upstream:
gltestsrc ! timeoverlay ! glimagesink
Using the correct blend modes for each case or converting to
premultipled in the very unlikely case that separate blend modes are
unavailable on ancient opengl hardware.
Attempting to use the MAX(1, display_rect) would result in the overlay
composition attempting to draw into 1x1 buffer and calculate some
grossly incorrect sizes.
previously failing case:
gltestsrc ! textoverlay text=GStreamer ! glimagesinkelement
It was checking for GST_IS_CAPS only and that would fail if the new
restriction caps was NULL and its documentation says it accepts NULL as
valid input.
If we have an upstream GST_EVENT_STREAM_START, use that one instead
of creating a new one which could be completely different from the
upstream one and drop information (like the stream flags and stream
object).
Only create a new event if we don't already have one from upstream
