Libvirt-java 0.4.9 works just fine with JNA 3.2.4 which is in
all distributions.
Future libvirt version require at least JNA 3.5.1 due to new methods
and memory management, but that is not our concern now.
By depending on the JNA in the distribution and adding it to the classpath
we can work just fine.
Some concepts included:
* the replace.properties location used by maven is parameterized to allow
for a build that does not modify the currently git tracked files
* package naming is updated along the lines of what was discussed on the
-dev mailing list and between committers at the Build a Cloud Day in Belgi
* package version pattern is updated (since we redo all package names,
we might as well drop the epoch)
Modify the spec file to package the agent files and the scripts
Some changes to the poms to put the java dependencies in the right place.
Move the agent script to the dedicated os dir in packaging.
