Documentation for the "guest-set-vcpus" command describes a proper algorithm how to set vcpus. This patch makes the following changes: - state of cpus that has not changed is not updated - if the command was partially successful the command is re-tried with the rest of the arguments to get a proper error message - code is more robust against malicious guest agent - fix testsuite to the new semantics
