Hi,

here's a patch that allows pcm_bluetooth.c to support
multiple period sizes (and thus gives application some
control over the wakeup/latency requirements it has to meet).
This patch works around an alsa-lib bug/limitation (triggered
if we allow the buffersize to vary). And a consequency,
buffersize is always fixed to 3*8192 bytes.

Patch available at:
http://sofia-sip.org/~vehmanek/bluez-patches/patch-20071120-kv-multiple-
periods-support.txt

PS Tested with alsa-lib pcm.c, alsa-utils speaker-test, 
   gstreamer (gst-launch + alsasink), and pulseaudio. The A2DP headsets
   used for testing were Nokia BH-501 and Logitech Freepulse Wireless.
