[Libguestfs] [RFC nbdkit PATCH 0/3] aligned .extents

Ultimately, both the blocksize and swab filters want to return aligned extents to the client. I'm posting this as a snapshot of my work in progress on how I plan to get there (it's not quite working yet, but I'm done for today and wanted to at least document my ideas). I might also add a convenience function for nbdkit_extents_offset, since we have a number of filters that repeat the same code for translating all extents from the plugin by an offset.
