[Libguestfs] [nbdkit PATCH v2 0/3] Saner --filter=blocksize defaults

[Eric Blake]

In v2:
- add debug statements at end of .config_complete, .prepare, .block_size
- formatting cleanups
- split old patch 1 into two patches: first, a mechanical rename into
  per-handle state with globals changed to config_*, second the
  deferral of setting defaults until .prepare
- in patch 2, rename test-blocksize-wrap.sh to
  test-blocksize-default.sh, and actually test two different exports
  from one server

Eric Blake (3):
  blocksize: Refactor to per-handle constraints
  blocksize: Defer per-handle initialization to .prepare
  blocksize: Default internal block size based on plugin
