monitor: add an implemention of qapi event emit method
The monitor is now hooked on the new event mechanism, so that later
patches can convert event callers one by one. Most code are copied from
old monitor_protocol_* functions with some modification.
Note that two build time warnings will be raised after this patch. One is
caused by no caller of monitor_qapi_event_throttle(), the other one is
caused by QAPI_EVENT_MAX = 0. They will be fixed automatically after
full event conversion later.

qapi script: add event support
qapi-event.py will parse the schema and generate qapi-event.c, then
the API in qapi-event.c can be used to handle events in qemu code.
All API have prefix "qapi_event".
The script mainly includes two parts: generate API for each event
define, generate an enum type for all defined events.
Since in some cases the real emit behavior may change, for example,
qemu-img would not send a event, a callback layer is used to
control the behavior. As a result, the stubs at compile time
can be saved, the binding of block layer code and monitor code
will become looser.

block: asynchronously stop the VM on I/O errors
With virtio-blk dataplane, I/O errors might occur while QEMU is
not in the main I/O thread. However, it's invalid to call vm_stop
when we're neither in a VCPU thread nor in the main I/O thread,
even if we were to take the iothread mutex around it.
To avoid this problem, we can raise a request to the main I/O thread,
similar to what QEMU does when vm_stop is called from a CPU thread.
We know that bdrv_error_action is called from an AIO callback, and
the moment at which the callback will fire is not well-defined; it
depends on the moment at which the disk or OS finishes the operation,
which can happen at any time. Note that QEMU is certainly not in a CPU
thread and we do not need to call cpu_stop_current() like vm_stop() does.
However, we need to ensure that any action taken by management will
result in correct detection of the error _and_ a running VM. In particular:
- the event must be raised after the iostatus has been set, so that
"info block" will return an iostatus that matches the event.
- the VM must be stopped after the iostatus has been set, so that
"info block" will return an iostatus that matches the runstate.
The ordering between the STOP and BLOCK_IO_ERROR events is preserved;
BLOCK_IO_ERROR is documented to come first.
This makes bdrv_error_action() thread safe (assuming QMP events are,
which is attacked by a separate series).

There patch protects vmstop_requested with a lock and introduces

Together with the new call to qemu_vmstop_requested in vm_start,
qemu_system_vmstop_request_prepare avoids a race where the VM could remain
stopped even though the iostatus of a block device has already been set
(for example).
qemu_system_vmstop_request_prepare however also lets the caller thread
delay observation of the state change until it has itself communicated
that change to the user. This delay avoids any possibility of a wrong
reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

two calls to format_string.
Also, this is a worsening of quality; previously we would produce

Fix these issues.

qdev: recursively unrealize devices when unrealizing bus
When the patch was posted that became 5c21ce7 (qdev: Realize buses
on device realization, 2014-03-12), it included recursive realization
and unrealization of devices when the bus's "realized" property
was toggled.
However, due to the same old worries about recursive realization
and prerequisites not being realized yet, those hunks were dropped when
committing the patch. Unfortunately, this causes a use-after-free bug
(easily reproduced by a PCI hot-unplug action).
Before the patch, device_unparent behaved as follows:
for each child bus
unparent bus ----------------------------.
| for each child device |
| unparent device ---------------. |
| | unrealize device | |
| | call dc->unparent | |
| '------------------------------- |
'----------------------------------------'
unrealize device
After the patch, it behaves as follows instead:
unrealize device --------------------.
| for each child bus |
| unrealize bus (A) |
'------------------------------------'
for each child bus
unparent bus ----------------------.
| for each child device |
| unrealize device (B) |
| call dc->unparent |
'----------------------------------'
At the step marked (B) the device might use data from the bus that is
not available anymore due to step (A).
To fix this, we need to unrealize devices before step (A). To sidestep
concerns about recursive realization, only do recursive unrealization
and leave the "value && !bus->realized" case as it is.
The resulting flow is:
for each child bus
unrealize bus ---------------------.
| for each child device |
| unrealize device (B) |
| call bc->unrealize (A) |
'----------------------------------'
unrealize device
for each child bus
unparent bus ----------------------.
| for each child device |
| unparent device |
'----------------------------------'
where everything is "powered down" before it is unassembled.
