----------------------------------------------------------------
Block layer patches:

- qcow2 cache option default changes (Linux: 32 MB maximum, limited by
  whatever cache size can be made use of with the specific image;
  default cache-clean-interval of 10 minutes)
- reopen: Allow specifying unchanged child node references, and changing
  a few generic options (discard, detect-zeroes)
- Fix werror/rerror defaults for -device drive=<node-name>
- Test case fixes
