ioemu: avoid name clashes due to LIST_* macros

Here is what I wrote in my submission to qemu upstream:

 qemu's audio subdirectory contains a copy of BSD's sys-queue.h, which
 defines a bunch of LIST_ macros.  This makes it difficult to build a
 program made partly out of qemu and partly out of the Linux
 kernel[1], since Linux has a different set of LIST_ macros.  It might
 also cause trouble when mixing with BSD-derived code.

 Under the circumstances it's probably best to rename the versions in
 qemu.  The attached patch does this.

 [1] You might well ask why anyone would want to do this.  In Xen we
 are moving our emulation of IO devices from processes which run on
 the host into a dedicated VM (one per actual VM) which we call a
 `stub domain'.  This dedicated VM runs a very cut-down `operating
 system' which uses some code from Linux.
