inter: Add channel property

The channel property allows multiple intersrc/sink pairs to find
each other.  It's a free-form text string that must match among
various inter elements.  Also fixed up documentation and latency
handling.

* The intervideosrc element does FIXME stuff.
* The intervideosrc element is a video source element. It is used
* in connection with a intervideosink element in a different pipeline,
* similar to interaudiosink and interaudiosrc.
*
* <refsect2>
* <title>Example launch line</title>
* |[
* gst-launch -v fakesrc ! intervideosrc ! FIXME ! fakesink
* gst-launch -v intervideosrc ! queue ! xvimagesink
* ]|
* FIXME Describe what the pipeline does.
*
* The intersubsrc element cannot be used effectively with gst-launch,
* as it requires a second pipeline in the application to send subtitles.
