Add support for Linux eventfd(7) in the UNIX event loop
eventfd(7) uses less resources than a pipe, as it only needs to store a single 64-bit integer, as opposed to a full buffer. It was introduced first on Linux version 2.6.22 and glibc 2.7. However, both the configure-time test and the runtime usage require the use of EFD_CLOEXEC for thread-safety, so this code will be enabled only for Linux 2.6.27 and up as well as glibc 2.9 and up.
