10557ca6b9 Fix playback start with sync_ptr mode 
Fix by Istvan Varadi <ivaradi@gmail.com>

- start the playback with snd_pcm_hw_start failed with -EPIPE, because
 some pointers were not updated. I attached a patch for alsa-lib 1.0.8,
 in which sync_ptr is called before SNDRV_PCM_IOCTL_START. It seems to
 solve the problem, though I don't know alsa-lib enough to be sure that
 this is the right solution...

6a6a70ffe7 Do hwsync of slave PCM on dmix 
Call hwsync of slave PCM on snd_pcm_hwsync() over dmix.
This reduces ocasional output noises, typically seen in xmms and bmp with
multi-threading on SMP/HT systems.

Disabled slowptr of default dmix definition again.

5e325ea18b Delayed start for dmix 
Introducing a private state for the delayed start of PCM stream.
This problem occurs when the rate plugin doesn't feed the data
properly before triggering START.  This results in weird problems,
e.g. an inifinte loop of artsd eating 100% CPU time.

To solve this problem, the state is marked as "pending" when no
data appears at the trigger, and the stream is started later at
the mmap commit.
