The ongoing QEMU multi-queue block layer effort makes it possible for multiple
threads to process I/O in parallel. The nbd block driver is not compatible with
the multi-queue block layer yet because QIOChannel cannot be used easily from
coroutines running in multiple threads

This error happens if we are not able to close the pipe to the
parent (to trace errors in the child process) and assign stderr to
/dev/null as required by the daemonizing convention.

v2 --> v3:
* Make "compressed" field mandatory, not optional;
* Adjust field description in qapi/block-core.json;
* Squash patch 3 into patch 2 so that failing tests don't break bisect;
* Update even more tests' outputs now that the field is mandatory.

Functions qcow2_get_host_offset(), get_cluster_offset(),
vmdk_co_block_status() explicitly report compressed cluster types when data
is compressed. However, this information is never passed further. Let's
