From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>
The naming used in the RPC protocols for the LXC monitor and
lock daemon confused the script used to generate systemtap
helper functions. Rename the LXC monitor protocol symbols to
reduce confusion. Adapt the gensystemtap.pl script to cope
with the LXC monitor / lock daemon naming conversions.
This has no functional impact on RPC wire protocol, since
names are only used in the C layer
