libxl: Implement domainGetMessages API

Browse Source 
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.
