This builds on the previous standalone patch I sent and audits
the permissions we check for other QMP operations on bitmaps.

This should make it more consistent overall, but it's not
complete and I'm heading out for a long weekend, but I wanted
them on the list.

I think I should reorder the patches at least, and I need to
write some tests that I can submit upstream in a polished form.

John Snow (6):
  dirty-bitmaps: allow merging to disabled bitmaps
  bitmaps: allow clear on disabled bitmaps
  bitmaps: prohibit merge on locked bitmaps
  bitmaps: add user_modifiable status checker
  bitmaps: prohibit enable/disable on locked/frozen bitmaps
  block/backup: prohibit backup from using in-use bitmaps
