032baddea3 docs: document missing VSERPORT_CHANGE event
The VSERPORT_CHANGE event was added in e2ae6159.  The patch for
this event was prepared at a time when this file was gone, even
though it got applied immediately after dfab4892 restored this
file.  Duplicate the documentation into this file, so that
anyone using this file instead of qapi will not miss out on this
new event.

* docs/qmp/qmp-events.txt (VSERPORT_CHANGE): Add.

db52658b38 docs: document missing POWERDOWN event
The POWERDOWN event was first documented in 0aab9ec3.  But since
dfab4892 later restored this file to the state prior to qmp events,
and we never documented it in the past, anyone using this file
instead of qapi will miss out on this event.  Tweak the existing
wording of SHUTDOWN to match 84321831, and make the difference
between the two events apparent.

dfab489214 qmp: add qmp-events.txt back
The conversion of events to the QAPI, resulted in the removal of the
docs/qmp/qmp-events.txt file. This was done to avoid having duplicated
information between qmp-events.txt and qapi-event.json.

However, qmp-events.txt contains examples and we're still not sure
how to proper install QAPI docs in the host. To avoid harming users,
it's better to re-add qmp-events.txt for now and deal with the
duplication later.

2bd3bce8ef 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).

95c6bff356 quorum: Add quorum mechanism.
This patchset enables the core of the quorum mechanism.
The num_children reads are compared to get the majority version and if this
version exists more than threshold times the guest won't see the error at all.

If a block is corrupted or if an error occurs during an IO or if the quorum
cannot be established QMP events are used to report to the management.

Use gnutls's SHA-256 to compare versions.

--enable-quorum must be used to enable the feature.
