32e6ac9c26 Add support for an explicit RTC change event
This introduces a new event type

   VIR_DOMAIN_EVENT_ID_RTC_CHANGE

This event includes the new UTC offset measured in seconds.
Thus there is a new callback definition for this event type

 typedef void (*virConnectDomainEventRTCChangeCallback)(virConnectPtr conn,
                                                        virDomainPtr dom,
                                                        long long utcoffset,
                                                        void *opaque);

If the guest XML configuration for the <clock> is set to
offset='variable', then the XML will automatically be
updated with the new UTC offset value. This ensures that
during migration/save/restore the new offset is preserved.

8613273458 Add support for an explicit guest reboot event
The reboot event is not a normal lifecycle event, since the
virtual machine on the host does not change state. Rather the
guest OS is resetting the virtual CPUs. ie, the QEMU process
does not restart. Thus, this does not belong in the current
lifecycle events callback.

This introduces a new event type

    VIR_DOMAIN_EVENT_ID_REBOOT

It takes no parameters, besides the virDomainPtr, so it can
use the generic callback signature.

6bae6677c8 Convert domain events example to new API
Convert the domain events example program to use the new
events APIs for one of its callback registrations to demo the
new API and interoperability with the old API.

1cfbfaa697 python example: poll(-0.001) does not sleep forever
The conversion from seconds to milliseconds should only be done for
actual delays >= 0, not for the magic -1 value used for infinite
timeouts.

7f7676e77b Don't call disabled timer callbacks in event-test.c
This fixes a segfault in the remote driver that occurs for example when
the event-test is run inside a domain-0 and libvirtd is also running.

93f77250b3 Rewrite example domain events programm for python
The existing python demo for domain events does not fully
implement the event loop contract. This makes the code useless
for real world applications. This change re-writes the demo so
that it has a full event loop implementation which is suitable
for application usage & better demonstrates integration

* examples/domain-events/events-python/event-test.py: Rewrite
  to include a real world usable event loop implementation

07613d2020 remove all trailing blank lines
by running this command:
git ls-files -z | xargs -0 perl -pi -0777 -e 's/\n\n+$/\n/'
This is in preparation for a more strict make syntax-check
rule that will detect trailing blank lines.
