The internal buffer handling is now better (cleaner) integrated with
snd_pcm_generic_*().

f1acd7726c PCM direct plugins - handle EINTR in the resource server 
The poll() call in the resource server for PCM direct plugins might be
interrupted with an signal. Handle the case gracefuly and don't exit
the server (which brings another problems - cannot connect to socket -
later).

4d7c53d280 Add snd_pcm_hw_params_get/set_export_buffer() 
Add snd_pcm_hw_params_get/set_export_buffer() API functions.
They control to ensure the buffer export to other processes.
If this flag is set, the local buffer of a plugin is exported over IPC shm.
Otherwise the buffer can be handled only locally (no shm).

Also fixed Version file for 1.0.9.

5227c7e170 Fix possible noises and optimization with dmix 
dmix transfers data in asynchronously so that it doesn't write on the
last active period.  This will allow the arbitrary buffer size in
future, too.

The hwsync call to slave is removed from commit and hwsync callbacks.
This hack was added to fix the noisy output (typically on xmms/bmp)
but it doesn't happen any more.  Now the hwsync behavior is as same as
on 1.0.8 (i.e. hwsync is called only when slowptr option is set).

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...
