io: fix check for handshake completion in TLS test
The TLS I/O channel test had mistakenly used && instead
of || when checking for handshake completion. As a
result it could terminate the handshake process before
it had actually completed. This was harmless before but
changes in GNUTLS 3.6.0 exposed this bug and caused the
test suite to fail.

util: remove the obsolete non-blocking connect
The non-blocking connect mechanism is obsolete, and it doesn't
work well in inet connection, because it will call getaddrinfo
first and getaddrinfo will blocks on DNS lookups. Since commit
e65c67e4 &
d984464e, the non-blocking connect of migration goes
through QIOChannel in a different manner(using a thread), and
nobody use this old non-blocking connect anymore.
Any newly written code which needs a non-blocking connect should
use the QIOChannel code, so we can drop NonBlockingConnectHandler
as a concept entirely.

So to on safe side, instead of having custom wrapper to do numbering
replace it with cpu_generic_init() and use S390CPUClass::next_cpu_id
which could serve the same purpose as static variable and move cpu->id
initialization to s390_cpu_initfn for CONFIG_USER_ONLY use-case.

qemu-iotests: test NBD over UNIX domain sockets in 083
083 only tests TCP. Some failures might be specific to UNIX domain
sockets.
A few adjustments are necessary:
1. Generating a port number and waiting for server startup is
TCP-specific. Use the new nbd-fault-injector.py startup protocol to
fetch the address. This is a little more elegant because we don't
need netstat anymore.
2. The NBD filter does not work for the UNIX domain sockets URIs we
generate and must be extended.
3. Run all tests twice: once for TCP and once for UNIX domain sockets.

qemu-iotests: improve nbd-fault-injector.py startup protocol
Currently 083 waits for the nbd-fault-injector.py server to start up by
looping until netstat shows the TCP listen socket.
The startup protocol can be simplified by passing a 0 port number to
nbd-fault-injector.py. The kernel will allocate a port in bind(2) and
the final port number can be printed by nbd-fault-injector.py.
This should make it slightly nicer and less TCP-specific to wait for
server startup. This patch changes nbd-fault-injector.py, the next one
will rewrite server startup in 083.

The problem is that nbd_client_init() uses
nbd_client_attach_aio_context() -> aio_co_schedule(new_context,
client->read_reply_co). Execution of read_reply_co is deferred to a BH
which doesn't run until later.
In the mean time blk_co_preadv() can be called and nbd_coroutine_end()
calls aio_wake() on read_reply_co. At this point in time
read_reply_co's ctx isn't set because it has never been entered yet.
This patch simplifies the nbd_co_send_request() ->
nbd_co_receive_reply() -> nbd_coroutine_end() lifecycle to just
nbd_co_send_request() -> nbd_co_receive_reply(). The request is "ended"
if an error occurs at any point. Callers no longer have to invoke
nbd_coroutine_end().
This cleanup also eliminates the segfault because we don't call
aio_co_schedule() to wake up s->read_reply_co if sending the request
failed. It is only necessary to wake up s->read_reply_co if a reply was
received.
Note this only happens with UNIX domain sockets on Linux. It doesn't
seem possible to reproduce this with TCP sockets.

qemu-iotests: Extend non-shared storage migration test (194)
This is the follow-up patch that was discussed[*] as part of feedback to
qemu-iotest 194.
Changes in this patch:
- Supply 'job-id' parameter to `drive-mirror` invocation.
- Once migration completes, issue QMP `block-job-cancel` command on
the source QEMU to gracefully complete `drive-mirror` operation.
- Once the BLOCK_JOB_COMPLETED event is emitted, stop the NBD server
on the destination QEMU.
- Check for both the events: MIGRATION and BLOCK_JOB_COMPLETED.
With the above, the test will also be (almost) in sync with the
procedure outlined in the document 'live-block-operations.rst'[+]
(section: "QMP invocation for live storage migration with
``drive-mirror`` + NBD").
