From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>
Update the gendispatch.pl script to get a little closer to
being able to generate code for the LXC monitor, by passing
in the struct prefix separately from the procedure prefix.
Also allow method names using virCapitalLetters instead
of vir_underscore_separator
