[Qemu-block] [PATCH v3 0/4] more blkdebug tweaks

[Eric Blake]

I found a crasher and some odd behavior while rebasing my
bdrv_get_block_status series, so I figured I'd get these things
fixed first.  This is based on top of Max's block branch.

Available as a tag at:
git fetch git://repo.or.cz/qemu/ericb.git nbd-blkdebug-status-v3

Since v2:
- defer the original patch 3 to a later series
- rebase to make sure test 177 passes at all times (I didn't
pinpoint which recent merge caused it, but the test now produces
json:{...} instead of blkdebug:... during patch 2)
- add more documentation of BDRV_BLOCK_RAW
- add R-b where appropriate
