[Libguestfs] [nbdkit PATCH 0/8] fd leak safety

There's enough here to need a review; some of it probably needs backporting to stable-1.12. This probably breaks tests on Haiku or other platforms that have not been as on-the-ball about atomic CLOEXEC; feel free to report issues that arise, and I'll help come up with workarounds (even if we end up leaving a rare fd leak on less-capable systems). Meanwhile, I'm still working on my promise to add an nbdkit_nanosleep for use in the delay and stat filters, and which makes nbdkit more responsive to ^C where it currently waits for a full delay to expire before exiting. (Nothing like finding several other pre-requisite bugs to fix first before getting to my real goal...)
