  hw/armv7m_nvic: Fix incorrect default for num-irqs property

Fix an incorrect default value for the num-irqs property (we were
attempting to override it from the default set by the parent class
but not succeeding, which meant that the lm3s6965evb model would
assert on startup attempting to wire up nonexistent irq lines).
Instead of trying to override the parent's Property array, we
define an instance_init function which runs after default setup
but before user property setting and can just fix up the default
value in the gic_state struct.

In the old QMP days, this code was used to find out QMP commands that
might be calling monitor_printf() down its call chain.

This is almost impossible to happen today, because the qapi converted
commands don't even have a monitor object. Besides, it's been more than
a year since I used this last time.

Let's just drop it.

qerror_abort() depends on the 'file', 'func' and 'linenr' members of
QError. However, these members are going to be dropped by the next
commit, so let's drop qerror_abort() in favor of printing an error
message to stderr plus a call to abort().

  migration: don't rely on any QERR_SOCKET_*

Use the in_progress argument for QERR_SOCKET_CONNECT_IN_PROGRESS. The
other errors are handled the same by checking if the error is set and
then calling migrate_fd_error() if it's.

It's also necessary to change inet_connect_opts() not to set
QERR_SOCKET_CONNECT_IN_PROGRESS. This error is only used by
tcp_start_outgoing_migration() and not changing it along with the
usage of in_progress would break migration.

Furthermore this commit fixes a bug. Today, there's a spurious error
report when migration succeeds:

(qemu) migrate tcp:0:4444
migrate: Connection can not be completed immediately
(qemu)

After this commit no spurious error is reported anymore.

The QERR_ macros are changed to contain a place holder value for the

Next commit will update the QERR_ macros with a proper ErrorClass

  qmp: switch to the new error format on the wire

IMPORTANT: this BREAKS QMP's compatibility for the error response.

This commit changes QMP's wire protocol to make use of the simpler
error format introduced by previous commits.

There are two important (and mostly incompatible) changes:

 1. Almost all error classes have been replaced by GenericError. The
    only classes that are still supported for compatibility with
    libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap,
    DeviceNotFound and MigrationExpected

 2. The 'data' field of the error dictionary is gone

As an example, an error response like:

  { "error": { "class": "DeviceNotRemovable",
         "data": { "device": "virtio0" },
         "desc": "Device 'virtio0' is not removable" } }

Will now be emitted as:

  { "error": { "class": "GenericError",
         "desc": "Device 'virtio0' is not removable" } }

  qmp: don't emit the RESET event on wakeup from S3

QEMU is basically using reset logic when waking up from S3. This
causes the QMP RESET event to be emitted, which is wrong. Also,
the runstate checks done in reset are not necessary for S3 wakeup.

Fix this by untangling wakeup from reset logic and passing
VMRESET_SILENT to qemu_system_reset() to avoid emitting the RESET
event.

  qmp: emit the WAKEUP event when the guest is put to run

Today, the WAKEUP event is emitted when a wakeup _request_ is made.
This could be the system_wakeup command, for example.

A better semantic would be to emit the event when the guest is
already running, as that's what matters in the end. This commit does
that change.

In theory, this could break compatibility. In practice, it shouldn't
happen though, as clients shouldn't rely on timing characteristics of
the events. That is, a client relying that the guest is not running
when the event arrives may break if the event arrives after the guest
is already running.

This commit also adds the missing documentation for the WAKEUP event.

  qmp: add SUSPEND_DISK event

Emitted when the guest makes a request to enter S4 state.

There are three possible ways of having this event, as described here:

 http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html

I've decided to add a new event and make it indepedent of SHUTDOWN.
This means that the SHUTDOWN event will eventually follow the
SUSPEND_DISK event.

I've choosen this way because of two reasons:

 1. Having an indepedent event makes it possible to query for its
    existence by using query-events

 2. In the future, we may allow the user to change what QEMU should
    do as a result of the guest entering S4. So it's a good idea to
    keep both events separated

  qapi: add query-cpu-definitions command (v2)

This command attempts to map to the behavior of -cpu ?.  Unfortunately, the
output of this command differs wildly across targets.

To accommodate this, we use a weak symbol to implement a default version of the
command that fails with a QERR_NOT_SUPPORTED error code.  Targets can then
override and implement this command if it makes sense for them.
