media: vivid: Add 'Is Connected To' menu controls
The video loopback functionality in vivid is very crude. What we really want is to be able to emulate connecting an HDMI or S-Video input to an HDMI or S-Video output, and the input and output can be in different vivid instances. Effectively this emulates what happens when you physically connect an HDMI or S-Video cable between two devices. In particular, this makes prototyping with vivid much more realistic. This patch creates a menu control for each HDMI or S-Video input. The menu control starts with "Test Pattern Generator" and "None" (i.e. disconnected). After that up to 62 HDMI or S-Video outputs are listed that you can connect the input to. If there are more than 62 HDMI or S-Video outputs, then those will not be included in the menu (currently menucontrols have max 64 entries). If an input is connected to an output, then all other 'Connected To' controls are updated to exclude that output to avoid having multiple inputs connected to the same output.
