[Qemu-devel] [PATCH 3/4] xen: Import Xen public headers used by xen-hvm.c

[Anthony PERARD <anthony.perard@citrix.com>]

Following "xen: Fix build with public headers", import other Xen
public headers that are describing interfaces.

The headers are cleaned up a bit while importing them. The header
guard symbols are changed to match QEMU's coding style, some other
part of the files that QEMU doesn't use are removed.

xen-mapcache.c doesn't needs params.h, so remove the include.
