Based-on: Kevin Wolf's block-next branch: http://repo.or.cz/qemu/kevin.git/shortlog/refs/heads/block-next
v2 of the series was here: https://lists.gnu.org/archive/html/qemu-devel/2016-11/msg03495.html since then, the first half was applied to 2.8; leaving just this second half to enhance blkdebug for 2.9. Rebase the patch on top of Kevin's work to make blkdebug byte-based, and address lots of good findings from Max.
