[Qemu-block] [PATCH for-2.7? 0/5] block: Use QemuOpts for runtime options

[Max Reitz]

The SSH and NBD block drivers currently directly extract their runtime
options from the options QDict they receive. This is bad practice and
can lead to segmentation faults (which, however, will always be a NULL
pointer dereference, so it should not be exploitable beyond a DoS).

This series fixes that by using QemuOpts instead (like all the other
block drivers do).

With this series applied, there are only two instances of "qdict_get"
left in block/, both of which appear to be safe.

  block/nbd: Use QemuOpts for runtime options
  block/blkdebug: Store config filename
  block/nbd: Store runtime option values
  iotests: Test case for wrong runtime option types
