[Libguestfs] [nbdkit PATCH 0/7] Implement structured replies in nbd plugin

I'm hoping to implement .extents for the nbd plugin; this is a prerequisite. I'm not sure about patch 3 - if we like it, I'll squash it to 2, if we don't, I think we are okay just dropping it. I'm also wondering if we have to worry about malicious plugins that don't populate the entire .pread buffer in an effort to get nbdkit to expose portions of the heap; my patch 7 loses some time on extra memset()s to avoid that, although it's probably in the noise compared to the time spent talking over sockets to the remote server.
