9207804912 Generic architecture support 
Support dmix on generic architectures without atomic operations but
using a semaphore to avoid concurrent accesses.  This is less effective
than atomic operations but should work on every system.

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.
