Mainline kernel support for eventfd(2) in linux aio was added between 2.6.21 and 2.6.22. Libaio after 0.3.107 has the header file, but presently few systems support it. Neither do we rely on an up-to-date libc6. Instead, this patch adds a header which defines custom iocb_common struct, and works around a potentially missing sys/eventfd.h.
