Add a multifd test for mapped-ram with passing of fds into QEMU. This is how libvirt will consume the feature. There are a couple of details to the fdset mechanism: - multifd needs two distinct file descriptors (not duplicated with dup()) so it can enable O_DIRECT only on the channels that do aligned IO. The dup() system call creates file descriptors that share status flags, of which O_DIRECT is one. - the open() access mode flags used for the fds passed into QEMU need to match the flags QEMU uses to open the file. Currently O_WRONLY for src and O_RDONLY for dst. Note that fdset code goes under _WIN32 because fd passing is not supported on Windows.
