Move FreeBSD from interface version 0x00030204 to 0x00030208. Updates are required to our grant table implementation before we can bump this further. sys/xen/hvm.h: Replace the implementation of hvm_get_parameter(), formerly located in sys/xen/interface/hvm/params.h. Linux has a similar file which primarily stores this function. sys/xen/xenstore/xenstore.c: Include new xen/hvm.h header file to get hvm_get_parameter(). sys/amd64/include/xen/xen-os.h: sys/i386/include/xen/xen-os.h: Correctly protect function definition and variables from being included into assembly files in xen-os.h Xen memory barriers are now prefixed with "xen_" to avoid conflicts with OS native primatives. Define Xen memory barriers in terms of the native FreeBSD primatives.
