  Modified files:
    sys/dev/sound/pcm    buffer.c buffer.h 
  Log:
  Fix huge memory leak within sound buffer (during channel destruction,
  buffer resizing, etc.) that was here since eon. Free all (unmanaged)
  allocated buffer through sndbuf_destroy() in case we forgot to call
  sndbuf_free(). For a managed buffer (mostly hw specific managed buffer),
  either provide CHANNEL_FREE() method with appropriate return value to
  invoke semi-automatic sndbuf_free() or simply do it on their own. If
  everything is failed, sndbuf_destroy() will come to the rescue as a
  final measure.
