My preference is for declarations immediately after the start of a 
block. eg, at start of a function, or immediately at start of a
nested if / while. I don't like have declarations scattered elsewhere 
in the functions because it means you end up having to scan the entire
function body to find where variables are declared, instead of just
looking at the start of the code block you are in. The vast majority
of libvirt code works this way, so I'd rather stick with the traditional
style and cleanup the few places not in compliance.
