Use different buffer metrics in the PulseAudio plugin

Hi!

Please commit this patch to alsa-plugins we ship in Fedora:

http://cvs.fedoraproject.org/viewcvs/*checkout*/devel/alsa-plugins/1.0.14-buffer-attr.patch?rev=1.1

It increases the "pre-buffering level" (i.e. start threshold) to the full buffer size minus one period. This makes PA work a little bit more like normal audio devices, and makes a few drop outs go away for software which uses very small period sizes.

It also increases the initial maximum buffer size, which allows a small overcommit. That's not really an issue, but cleaner nonetheless so I smuggled it into this patch.
