  iotests: New test 223 for exporting dirty bitmap over NBD (2018-07-02 
19:50:37 -0500)

Discussed but not included here: we need to ensure that during a
backup sync:none job, writes must NOT be permitted to the fleecing
node's backing file as long as reads are being served from the same
area. Hopefully we can fix this via the existing job, instead of
having to add a new filter node.

nbd patches for 2018-07-02

Bug fixes and iotest exposure of fleecing via NBD (serving a
read-only point-in-time view via blockdev-backup sync:none,
as well as serving dirty bitmaps over NBD), including a new
x-dirty-bitmap parameter when opening NBD clients as the
counterpart to x-nbd-server-add-bitmap. Also a random fix
for iscsi block_status spotted by Coverity that missed other
miscellaneous trees.

- Eric Blake: nbd/server: Fix dirty bitmap logic regression
- Eric Blake: iscsi: Avoid potential for get_status overflow
- John Snow/Vladimir Sementsov-Ogievskiy: 0/2 block: formalize and test fleecing
- Eric Blake: 0/2 test NBD bitmap export
