[vdr] Patch: Add 'MUTEON' and 'MUTEOFF' options to the SVDRP VOLU command

Hi all,

I made a tiny patch to extend the SVDRP VOLU command.
Up until now VDR only had an option to _toggle_ the current audio muted status,
but no options to force the audio muted status on or off. I want to mute the
audio via SVDRP and unmute it again later.

My usecase: I'm running mpd on the same host as VDR, if I start playing music
with mpd from my tablet I can mute VDR automatically with a shell script and
unmute it again after stopping the music.
Using the (already implemented) VOLU 0 command also mutes the audio, but the
previous audio volume gets lost, so you cannot unmute audio again and return to
the previous volume.

Best regards
