identify if the data loss happened either at Kernel or userspace side.

Update documentation accordingly.

The demux documentation is pretty poor nowadays: most of the
structs and enums aren't documented at all.

Add proper kernel-doc markups for them and use it.

Now, the demux API data structures are fully documented :-)

So, get rid of it.

The name of the subsystem is "media", and not "linux_tv". Also,
as we plan to add other stuff there in the future, let's

clearer.

No functional changes.
