[libvirt] [PATCH] libxl: support soundhw for hvm domains



The xend driver and the parsing/formating code in src/xenconfig
have long supported soundhw.  Add support in the libxl driver too.

Signed-off-by: Jim Fehlig <jfehlig suse com>

This patch continues the tradition of silently ignoring unsupported
config in the libxl driver.  But it is an improvement; post-patch
only sound devices after the first are ignored :-).
