[xen] Import selected public headers
Import selected headers from the xen/include/public directory of the Xen repository at git://xenbits.xen.org/xen.git The script ./include/xen/import.pl can be used to automatically import any required headers and their dependencies (in a similar fashion to ./include/ipxe/efi/import.pl). Trailing whitespace is stripped and an appropriate FILE_LICENCE declaration is added to each header file. Signed-off-by: Michael Brown <mcb30@ipxe.org>
