[mythtv-users] Is mythfrontend's AirPlay support supposed to be audio-only or audio-and-video?

Note that in master I have fixed most issues people would have been
experiencing with AirPlay.
The main one being that the device is seen in iOS/iTunes but nothing
happens when you try to play.

I intend to backport all those changes to fixes/0.25 as it makes
AirPlay almost fully complete when it comes to video and audio
playback.

There is a change of behaviour too, in that the airplay device appears
like an AppleTV does:
in music you see one speaker device
and in video, you see one audio/video device

You won't see two devices anymore one doing nothing in iOS Music, and
in Video app: one doing just audio and one doing audio+video.

I might add the ability to control that behaviour later if people feel
like they want audio only output in video playback (so the video plays
locally on the iPhone/iPad and the audio plays on myth frontend)

AirPlay is made of two services, RAOP (used to be called AirTunes) and AirPlay.
RAOP does audio only, and requires the presence of the RAOP rsa key in ~/mythtv.
AirPlay is a audio/video service, and doesn't require anything else
but the MYTHTV_AIRPLAY environment variable to be set

An Airport Express advertise the RAOP service
An Apple TV advertises both RAOP and AirPlay, but shows them as one device only.
