pci.mak includes a lot of devices - and most of them do not make
sense on s390x, like USB controllers or audio cards. These devices
also show up when running "qemu-system-s390x -device help" and thus
could raise the hope for the users that they could use these kind
of devices with qemu-system-s390x. To avoid this confusion, we
should not include pci.mak and rather include the bare minimum
manually instead.

This patch introduces two new machine options for indicating the state of
AES/DEA key wrapping functions.  This controls whether the guest will
have access to the AES/DEA crypto functions.

aes_key_wrap="on | off" is changed to aes-key-wrap="on | off"

Synchronizes the guest TOD clock across a migration by sending the guest TOD
clock value to the destination system. If the guest TOD clock is not preserved
across a migration then the guest's view of time will snap backwards if the
destination host clock is behind the source host clock. This will cause the
guest to hang immediately upon resuming on the destination system.

s390_flic_init() is a helper to create and realize either
"s390-flic-kvm" or "s390-flic-qemu".  When qdev_init() fails, it
complains to stderr and succeeds.

Except it can't actually fail, because the "s390-flic-qemu" is a dummy
without a realize method, and "s390-flic-kvm"'s realize can't fail,
even when the kernel device is really unavailable.  Odd.

Replace qdev_init() by qdev_init_nofail() to make "can't fail" locally
obvious, and get rid of the unreachable error reporting.

This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.

Note that the code generating backends still manipulate labels as int.

With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

There is a not-so-subtle race in QSLIST_INSERT_HEAD_ATOMIC.

Because atomic_cmpxchg returns the old value instead of a success flag,
QSLIST_INSERT_HEAD_ATOMIC was checking for success by comparing against
the second argument to atomic_cmpxchg.  Unfortunately, this only works
if the second argument is a local or thread-local variable.

If it is in memory, it can be subject to common subexpression elimination
(and then everything's fine) or reloaded after the atomic_cmpxchg,
depending on the compiler's whims.  If the latter happens, the race can
happen.  A thread can sneak in, doing something on elm->field.sle_next
after the atomic_cmpxchg and before the comparison.  This causes a wrong
failure, and then two threads are using "elm" at the same time.  In the
case discovered by Christian, the sequence was likely something like this:

    thread 1                   | thread 2
    QSLIST_INSERT_HEAD_ATOMIC  |
      atomic_cmpxchg succeeds  |
      elm added to list        |
                               | steal release_pool
                               | QSLIST_REMOVE_HEAD
                               | elm removed from list
                               | ...
                               | QSLIST_INSERT_HEAD_ATOMIC
                               |   (overwrites sle_next)
      spurious failure         |
      atomic_cmpxchg succeeds  |
      elm added to list again  |
                               |
    steal release_pool         |
    QSLIST_REMOVE_HEAD         |
    elm removed again          |

The last three steps could be done by a third thread as well.
A reproducer that failed in a matter of seconds is as follows:

- the guest has 32 VCPUs on a 28 core host (hyperthreading was enabled),
  memory was 16G just to err on the safe side (the host has 64G, but hey
  at least you need no s390)

- the guest has 24 null-aio virtio-blk devices using dataplane
  (-object iothread,id=ioN -drive if=none,id=blkN,driver=null-aio,size=500G
  -device virtio-blk-pci,iothread=ioN,drive=blkN)

- the guest also has a single network interface.  It's only doing loopback
  tests so slirp vs. tap and the model doesn't matter.

- the guest is running fio with the following script:
