We're seeing various issues with the SDL audio backend and want to
switch to the pulseaudio backend. See e.g.

  https://bugzilla.redhat.com/495964
  https://bugzilla.redhat.com/519540
  https://bugzilla.redhat.com/496627

The pulseaudio backend seems to work well, so we should allow it to be
selected as the default.

The patch above is in qemu in Fedora 11.  Pulseaudio seems to be the
only way to get decent sound quality on default installation in that
distro, and there does not seem to be a reason not to allow pulseaudio
be the default, if the user chooses to make it so at configure time.

Please comment or commit.
