QEMU will likely report the details of it shutting down, particularly
whether the shutdown was initiated by the guest or host.  We should
forward that information along, at least for shutdown events.  Reset
has that as well, however that is not a lifecycle event and would add
extra constants that might not be used.  It can be added later on.

When using thin provisioning, management tools need to resize the disk
in certain cases. To avoid having them to poll disk usage introduce an
event which will be fired when a given offset of the storage is written
by the hypervisor. Together with the API which will be added later, it
will allow registering thresholds for given storage backing volumes and
this event will then notify management if the threshold is exceeded.

This is where e.g. Debian puts it.

When changing the metadata via virDomainSetMetadata, we now
emit an event to notify the app of changes. This is useful
when co-ordinating different applications read/write of
custom metadata.

qemu-bridge-helper is only called from libvirtd, it has to be moved
from the qemu domain abstraction to the usr.sbin.libvirtd profile.

This event is emitted when a nodedev XML definition is updated,
like when cdrom media is changed in a cdrom block device.

Also includes node device update event implementation for udev
backend, virsh nodedev-event support, and event-test support

On error, asprintf returns -1 and the contents of the string
pointer is undefined. In the rest of the libvirt code,
the virAsprintf wrapper takes care of that.

Check the return value and report a generic error, since we
purposefully avoid linking to virutil.

Some of the examples make use of asprintf and strtol functions (to keep
things simple) which are prohibited to use within our code (enforced by
syntax-check). Therefore besides adding some examples, this patch also updates
cfg.mk to exclude examples directory from asprintf and strtol rules, as well as
updates .gitignore to exclude all the new admin binaries created in the
'examples' dir.

The VIR_STORAGE_POOL_EVENT_REFRESHED constant does not
reflect any change in the lifecycle of the storage pool.

It should thus not be part of the storage pool lifecycle
event set, but rather be a top level event in its own
right. Thus we introduce VIR_STORAGE_POOL_EVENT_ID_REFRESH
to replace it.

We have this code in our Makefile that tries to remove
/etc/libvirt/nwfilter if directory is left empty after all our
example nwfilters were uninstalled. However, the check for that
is missing quotation marks thus rendering the test useless:

  rmdir "/some/path/libvirt.git/_install/etc/libvirt/nwfilter"
/bin/sh: line 0: test: too many arguments

Use verify to force adding new events by means of static assertions.

When adding the static check I've noticed that one other event is
missing.

Rather than copying loads of ugly code, let's help out by a few C
tricks.

Avoid forgetting to add the correct fields to the switches in
event-test.

Make them return "uknown" for invalid values without breaking compiler
checks to add new values.

Arrays would induce crash if a new value was introduced without adding
it here. This could happen for
VIR_DOMAIN_EVENT_DISK_DROP_MISSING_ON_START

Break long lines and format headers correctly.
