Similarly to 790f912b4 which rejects snapshots names containing, this commit changes virDomainSaveXML to reject domains with a '/' in their name.

Seems this should be in a more "general" location. Would the same rules apply to other objects (networks, storage, etc.)? What other characters should be avoided? Having a comma, semi-colon, colon, etc. could have interesting results. Perhaps somewhat different rules for each, but using some sort of type of object enum to weed out object specific rules (eg, VIR_IS_ type macros). Perhaps someone who's been on the project a bit longer has a suggestion or two... John
