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.
