    libxl: Implement domainGetMessages API
    
    Since commit 46783e6307a, the 'virsh dominfo' command calls
    virDomainGetMessages to report any messages from the domain.
    Hypervisors not implementing the API now get the following
    libvirtd log message when clients invoke 'virsh dominfo'
    
    this function is not supported by the connection driver: virDomainGetMessages
    
    Although libxl currently does not support any tainting or
    deprecation messages, provide an implementation to squelch
    the previously unseen error message when collecting dominfo.
