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).

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).

automagically rather than the error return.
