If the event loop takes a very long time todo something, it is
possible for the 'self pipe' buffer to become full at which
point the entire event loop + remote driver deadlock. Use a
boolean flag to ensure we have strict one-in, one-out behaviour
on writes/reads of the 'self pipe'
The events demo program is slightly misleading printing
myDomainEventCallback1 EVENT: Domain f14i686(-1) Added
which is not distinguishing Add vs Update events. It should have
been doing
myDomainEventCallback1 EVENT: Domain f14i686(-1) Defined Updated
* examples/domain-events/events-python/event-test.py: Fully print
event detail info string
The generator was disabled for the new event callbacks, since they
need to be hand written. This patch adds the C and python glue to
expose the new APIs in the python binding. The python example
program is extended to demonstrate of the code
* python/libvirt-override.c: Registration and dispatch of events
at the C layer
* python/libvirt-override-virConnect.py: Python glue for events
* examples/domain-events/events-python/event-test.py: Demo use
of new event callbacks
The conversion from seconds to milliseconds should only be done for
actual delays >= 0, not for the magic -1 value used for infinite
timeouts.

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
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.
python/libvir.py python/libvirt_wrap.h python/types.c:
adds support for events from the python bindings, also
improves the generator allowing to embbed per function
definition files, patch by Ben Guthro
* examples/domain-events/events-python/event-test.py: also
adds a programming example
