command: redo ancient TV/DVB/PVR commands

Convert all these commands to properties. (Except tv_last_channel, not
sure what to do with this.) Also, internally, don't access stream
details directly, but dispatch commands with stream ctrls.

Many of the new properties are a bit strange, because they're write-
only. Also remove some OSD output these commands produced, because I
couldn't be bothered to port these.

In general, this makes everything much cleaner, and will also make it
easier to e.g. move the demuxer to its own thread.

Don't bother updating input.conf, but changes.rst documents how old
commands map to the new ones.

Mostly untested, due to lack of hardware.
