    Fix for incorrect voicemail duration in external notifications
    
    This patch fixes an issue where the voicemail duration was being reported
    with a duration significantly less than the actual sound file duration.
    Voicemails that contained mostly silence were reporting the duration of
    only the sound in the file, as opposed to the duration of the file with
    the silence.  This patch fixes this by having two durations reported in
    the __ast_play_and_record family of functions - the sound_duration and the
    actual duration of the file.  The sound_duration, which is optional, now
    reports the duration of the sound in the file, while the actual full duration
    of the file is reported in the duration parameter.  This allows the voicemail
    applications to use the sound_duration for minimum duration checking, while
    reporting the full duration to external parties if the voicemail is kept.
