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

[Eric Blake]

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.

Eric Blake (3):
  vector: Add VECT_remove
  extents: Add nbdkit_extents_aligned()
  RFC swab: Re-enable .extents
