[vdr] SVDRP commands that should exist

[Paavo Hartikainen <pahartik@sci.fi>]

These are commands that are missing from SVDRP.  AFAIK, implementing
these is possible with existing features of VDR.

PLAY <number> [ position ]

    Play recording <number> as returned by LSTR from position it was
    left at, unless position is defined as number of seconds from the
    beginning.  Returns name, total length and position of recording.

STOP

    If recording is being played, stop it.  Returns name, total length
    and position of recording.

JUMP [ position ]

    If recording was being played, jump to position.  If recording was
    not being played, change the stored position of last played
    recording.  Returns name, total length and position of recording.


Then another command that would be useful.  This would require some
additional features and might be nice for user outside SVDRP as well.
This is what I would like to see in VDR but might be quite difficult
to implement well.

SUSP [ audio | video | all | none ]

    Stop receiving and displaying video.  Somewhat like mute, but not
    only for audio.  Optionally it would turn off audio and video and
    release devices.  One could for example use gxine to play audio
    and video without stopping VDR.

    Outside SVDRP, pressing <Power> key would cause menu to appear
    where one can choose between:

        - poweroff
        - quit VDR
        - SUSP all
        - SUSP audio
        - SUSP video

    Pressing <Power> key while anything is suspended would cause VDR
    to return to normal operation (SUSP none) again.
